Get value from string php

Edited my que.. Value also contains some letters

I have search through so many questions but I couldn't find it.
I have string like this:

Ab2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134

What I want to do is get all values only in output like:

284t810 39h2047 3700p134

I used substr and strpos combine to get value but it only removes portion of data ahead of first "value=" so output is like:

284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134

I just want to delete everything else and keep only numbered value which is after "value="

Sorry if there is any confusion. Using stackoverflow for first time.

use this code: with this code you get any strings that they are after value=. I think this is the easiest solution.

$str = 'b2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134';
preg_match_all['#value=[[^\s]+]#', $str, $matches];

echo implode[' ', $matches[1]];

@Kesh : \s means space. [^\s] means everything except space. and + means at least one char. and the [] around it is for selecting the string so we can use it after the operation. [[^\s]+] means select everything except space and put them to the $matches

Do it via regular expression

$str = 'b2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134';

preg_match_all["/value=[[^\s]+]/", $str, $matches];

echo implode[" ", $matches[1]];

Here you can see demo

You could use a lookahead to find all value= and take all characters after that until a space character is encountered then implode the results using a space.

$string = 'Ab2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134';

preg_match_all["/[?=value\=[[^\s]+]]/", $string, $matches];

$result = implode[" ", $matches[1]];

The output is

284t810 39h2047 3700p134

Sticking to substr[] and strpos[] you can do the following as long as you can trust the format of the data.

$s = 'Ab2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134';
echo "Input string: $s
\n";

$out = '';
$offset = 0;
while [ $offset = strpos[$s,'=',$offset] ]
{
  $end = strpos[$s,' ',$offset];
  if [ $end ]
    $out .= substr[$s,$offset+1,$end-$offset];
  else
    $out .= substr[$s,$offset+1];

  $offset++;
}

echo "Output string: $out
\n";

This will yield the following:

Input string: Ab2cds value=284t810 shfn4wksn value=39h2047 hs2krj8dne value=3700p134
Output string: 284t810 39h2047 3700p134

I'm guessing that perhaps you wanted to use a strpos[] based solution for efficiency purposes.

Try this

$data = 'Ab2cds value=284810 shfn4wksn value=391047 hs2krj8dne value=3700134';
$array_data = explode[' ', $data];
foreach [$array_data as $array_dat] {
    $data_list[] = strstr[$array_dat, '='];
}
foreach [$data_list as $key => $value] {
    $array[$key] = str_replace['=', '', $value];
}
var_dump[array_filter[$array]];

OUTPUT

array[3] { [1]=> string[6] "284810" [3]=> string[6] "391047" [5]=> string[7] "3700134" }
