Can we include one php file multiple times?

"; echo " "; //echo ""; echo "
" ; include ('pictures.php'); echo ""; } echo "

I have a php-file called kal_test.php which gives a value to the variable $vbl. This variable is needed in the file called kal_generator.php which produces a table from that variable (I'll spare you the details). It goes like this:


[kal_test.php]


[kal_test.php]





";
    foreach ($v1 as $v2) {
        echo "";
    }
    echo "\n";
}
?>
blablabla
$v2

This set-up works fine but I can't make two of those appear on the same page, like this:

[kal_test.php]


This will give the following result:

//here comes the header

 // table created with $vbl = "14/09/2011"
  
blablabla
thisworks
thisworks
//here should the second table be and also the rest of the page (footer), this is completely missing

What am I doing wrong? Thanks!

The include function will allow you to include the same file multiple times so you can use it within a loop.,This will include the product.php file as many times as it loops through the $products array, but if this was using a include_once function it will only display the product.php file once.,The include_once function is exactly the same as the include function except it will limit the file to be used once.,The include function is used in PHP when you want to include a file within the current process. It takes one argument which will be a string to the file path you want to include.

include 'header.php';

<div id="content">

div>

include 'footer.php';

include_once 'main_page.php';

foreach($products as $product) {
   
   include 'product.php';
}

foreach($products as $product) {
   
   include_once 'product.php';
}

The function can only be defined once, and so you want to include this outside of the loop.,Is it possible to have an include function several times on the same page pointing to the same php file?,It is perfectly feasible to use the include function more than once. Any inline code in the included file will be run as though the included file were run. This can sometimes cause unpredictable results and requires certain amount of care, particularly with variables., Maybe post some of the code in the images.php file so we can see what is being included? We may be able to give you some pointers...

sure its basically just an image swapper with some javascript:

;

;

;

;


<script type="text/javascript">
   

   function changeImage(ref) {

      var img = (document.all) ? document.all.imageSample : document.getElementById('imageSample');

      var myImage = [];

      var imagea = "";
      var imageb = "";
      var imagec = "";
      var imaged = "";

      

      myImage['red'] = new Image();

      myImage['red'].src = imagea;

      

      myImage['green'] = new Image();

      
      myImage['green'].src = imageb;

      myImage['blue'] = new Image();
      
      
      myImage['blue'].src = imagec;

      myImage['black'] = new Image();

      myImage['black'].src = imaged;

If the code in the pictures.php file IS in a class, then yes, you will need to create a new object, but it depends on the name of the class (as opposed to the file). For example, if the pictures.php file contains the following line:

then results.php would need to create a new PictureManager object like so:

$pictures = new PictureManager();

Here is the code for results.php

 '".$stressa."' ORDER BY RAND() LIMIT ".$timea." ";
//"' and pass = '".$password."'";
	$result = @mysql_query($query, $connection) 

	

	
	
or die ("Unable to perform query
$query".mysql_error()); while ($row=mysql_fetch_array($result)) { { echo "

" . $row[1] . "

" . $row[1] . "
"; } ?>

So your loop code is equivalently:

echo "<tr>";
   echo "<td>
      <h2>" . $row[1] . "
   td>
   h2> ";
   echo "<td>" . $row[1] . "td> <br> " ;
   $imagea= $row[3];
   $imageb= $row[4];
   $imagec= $row[5];
   $imaged= $row[6];
   echo "tr>";

Sorry I have omitted the end of the code. The function is called when the different links are clicked on pictures.php:

<tr>
   <td title="Red"><a href="javascript:void(0);" onClick="changeImage('red');">Imagea>td>

tr>
<tr>
   <td title="Green"><a href="javascript:void(0);" onClick="changeImage('green');">Video Demoa>td>
<tr>
<tr>
   <td title="Blue"><a href="javascript:void(0);" onClick="changeImage('blue');">3D Demoa>td>
tr>
<tr>
   <td title="Black"><a href="javascript:void(0);" onClick="changeImage('black');">3D Extendeda>td>

tr>
table>

In this tutorial you will learn how to include and evaluate the files in PHP.,The basic syntax of the include() and require() statement can be given with:,You might be thinking if we can include files using the include() statement then why we need require(). Typically the require() statement operates like include().,The only difference is — the include() statement will only generate a PHP warning but allow script execution to continue if the file to be included can't be found, whereas the require() statement will generate a fatal error and stops the script execution.

"PHP allows you to include file so that a page content can be reused many times. It is very helpful to include files when you want to apply the same HTML or PHP code to multiple pages of a website." There are two ways to include file in PHP.,PHP include is used to include a file on the basis of given path. You may use a relative or absolute path of the file. ,Easy editable: If we want to change anything in webpages, edit the source file included in all webpage rather than editing in all the files separately. ,In case of require() if the file (welcome.php) is not found in the same directory. The require() will generate a fatal error and stop the execution of the script, as you can see in the below output.

   PHP |

For more information on how PHP handles including files and the include path, see the documentation for include_path. , include , The include expression includes and evaluates the specified file. , Another way to "include" a PHP file into a variable is to capture the output by using the Output Control Functions with include. For example:

(PHP 4, PHP 5, PHP 7, PHP 8)

The include expression includes and evaluates the specified file.

The documentation below also applies to require.

Files are included based on the file path given or, if none is given, the include_path specified. If the file isn't found in the include_path, include will finally check in the calling script's own directory and the current working directory before failing. The include construct will emit an E_WARNING if it cannot find a file; this is different behavior from require, which will emit an E_ERROR.

Note that both include and require raise additional E_WARNINGs, if the file cannot be accessed, before raising the final E_WARNING or E_ERROR, respectively.

To demonstrate how you can include the same file multiple times using include we create a PHP file named index.php. ,We call the simplelist.php file twice using include_once to demonstrate how the statement works in PHP.,Inside the PHP script we have the code below. We call a PHP file named simplelist.php twice using the include statement. ,If you do not want the file included multiple times, you will need to use include_once instead. I also recommend using include_once if you are including code that might cause code duplication problems.

Inside the PHP script we have the code below. We call a PHP file named simplelist.php twice using the include statement.

<html>

<body>
   <p>My first include.p>
   
   <p>My Second include.p>
   
body>

html>

The simplelist.php file is in the same directory as the index.php file.

<ul>
   <li>1li>
   <li>2li>
   <li>3li>
ul>

The output below is the HTML output of the PHP files above. You can see our PHP file containing the HTML list was included twice.

<html>

<body>
   <p>My first include.p>
   <ul>
      <li>1li>
      <li>2li>
      <li>3li>
   ul>
   <p>My Second include.p>
   <ul>
      <li>1li>
      <li>2li>
      <li>3li>
   ul>
body>

You are receiving this error because the file testmodify.php contains the definition for "show". A second inclusion of the file caused by your loop attempts to define the object show again, which cannot be done.,Here is another SO question about someone trying to redefine a function. Php and redifining,Fatal error: Cannot redeclare show() (previously declared in testmodify.php:14) in testmodify.php on line 39,You can do something like (in your testmodify.php script):

Yeah I know this is probably not the best way to perform this. However I have a script which I would like to call multiple times with parameters and hand over two variables. The code I have so far looks like this:

$testfeld = array('User1' => '400028',
   'User2' => '400027'
);

foreach($testfeld as $key => $value) {
   $_GET['cmd'] = 'modify';
   include("testmodify.php");
}
Copy code

You can do something like (in your testmodify.php script):

if (!function_exists("show")) {
   function show($parameters) {
      
   }
}
Copy code


How many times can you include a PHP file in another PHP file?

It is possible to insert the content of one PHP file into another PHP file (before the server executes it), with the include or require statement. The include and require statements are identical, except upon failure: require will produce a fatal error (E_COMPILE_ERROR) and stop the script.

How do I include two PHP files?

The include() statement is used to include a php file in another file. This way you can write a piece of code in a php file and can use it to multiple files through include() statement.

What happens if a script defines the same function more than once?

If you accidentally include the same file (typically functions or classes files) more than one time within your code using the include or require statements, it may cause conflicts. To prevent this situation, PHP provides include_once and require_once statements.

What is the difference between include and include_once in PHP?

The include() function is used to include a PHP file into another irrespective of whether the file is included before or not. The include_once() will first check whether a file is already included or not and if it is already included then it will not include it again.
