php - How to return matches array and also result string using preg_replace? -

i need accomplish 2 things, , wondering if both can accomplished preg_replace.

i need alter string. right using preg_replace:

preg_replace($terms,$replace_with,$string,1); 

where $terms array of terms, , $replace_with array.

but need return matches in separate array (to update other values later), because there several terms, don't know 1 has matched.

the way know how accomplish this, run preg_match first, default returns matches array, , preg_replace replace string new values.

is there way return string, , matches preg_replace only?

my end goal, have altered $string (which accomplished preg_replace), array $terms matched.

no, if $terms , $replace_with have numeric keys (without gaps) can use preg_replace_callback:

$matches = []; foreach($terms $k=>$term) {     $rep = $replace_with[$k];     $string = preg_replace_callback($term, function ($m) use ($rep, &$matches) {         $matches[] = $m[0];         return $rep;     }, $string, 1); } 

note using foreach + preg_replace[_callback] same thing using preg_replace array first parameter or using preg_replace_callback_array. (ie: string parsed once item.)
