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=39h1047 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 & put them khổng lồ the $matches

Do it via regular expression

$str = "b2cds value=284t810 shfn4wksn value=39h1047 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= & take all characters after that until a space character is encountered then implode the results using a space.

$string = "Ab2cds value=284t810 shfn4wksn value=39h1047 hs2krj8dne value=3700p134";preg_match_all("/(?=value=(<^s>+))/", $string, $matches);$result = implode(" ", $matches<1>);The output đầu ra is

284t810 39h1047 3700p134

Sticking khổng lồ substr() & strpos() you can vị the following as long as you can trust the format of the data.

$s = "Ab2cds value=284t810 shfn4wksn value=39h1047 hs2krj8dne value=3700p134";echo "Input string: $s ";$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 ";This will yield the following:

Input string: Ab2cds value=284t810 shfn4wksn value=39h1047 hs2krj8dne value=3700p134Output string: 284t810 39h1047 3700p134I"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"
