   Re: exit a php function in middle and continue other lines of code

   I'm guessing what you're looking for is 'return' and not 'exit'.

   'return' is a language construct that allows you to exit a function [with possible return value].
   'exit' is a function that stops execution for the entire script.

   Delete it. They just clutter threads anyway.

   i also tried return, But php keep doing something after return, it executes the whole code and then return. and that cause script to failure Maximum Execution Time 30 Seconds [ Error Comes ]

   This has no meaning.

   PHP Code:

   function abc[]
{
  return;
} 


   This also has no meaning. It is the same as:
   

   PHP Code:

   function abc[] {} 


   This:
   

   PHP Code:

   function abc[] {}

   echo

   'HELLO';
abc[];
echo 'WORLD'; 


   will output:
   
   

   But php keep doing something after return, it executes the whole code and then return. and that cause script to failure Maximum Execution Time 30 Seconds [ Error Comes ]

   This means you have created an infinite loop.

   Post the code that you tried.

   Re: exit a php function in middle and continue other lines of code

   i have noticed, that return still continues to the end of the loop, i just want to come out of the function and then continue rest script

   here is the code

   Code:

   i have just found a temp solution for now, to redirect to another page instead of exit;

   Ah... you didn't mention recursion.

   Returning does exit the function. The problem is that you're expecting it to exit the whole recursion loop, but instead what it actually does is exit the current stack frame only.

   One technique you could use is to return a value [true or false] to indicate whether or not to continue recursing:

   PHP Code:

   Traversing a tree can be done without recursion, but it is not as intuitive.

   Also, you avoid using echo to emit HTML.

   Also also, it strikes me that you might be able to avoid recursion altogether [and many queries] if you restructured your database.

    Hi,
    i don't know why i can't get out of the loop from the specific place only.

    is it possible to exit from the recursive function below and process other task in the script ? without using of exit[0] function?

    Please make it out after printing the red line in the code.

    Code:

    You need to check the return value like I did in post 7.
