preg replace - PHP hiding multiple phone numbers -

i trying replace phone numbers [hidden] , show them on click. works great when there 1 number. when there more, hides it, problem returns same number both hidden fields.

$check ='111 111 1111 / 222 222 2222';       preg_match('/[(]*\d{3}[)]*\s*[.\- ]*\d{3}[.\- ]*\d{4}/', $check, $phone_matches);  echo sizeof($phone_matches); //returns 1, why not 2?? 

pretty much, if can me sizeof($phone_matches) show correct amount, should there!

edit:

for($i=0; $i<sizeof($phone_matches[0]); $i++){     $check = preg_replace('/[(]*\d{3}[)]*\s*[.\- ]*\d{3}[.\- ]*\d{4}/', '<span class="hide">'.$phone_matches[0][$i].'</span><span class="show">show phone</span>', $check); }   echo $check; 

you want use preg_match_all, not preg_match

preg_match_all('/[(]*\d{3}[)]*\s*[.\- ]*\d{3}[.\- ]*\d{4}/', $check, $phone_matches); print_r($phone_matches); 

but note sizeof($phone_matches) still 1, since array of matches $phone_matches[0].

to iterate through matches do:

foreach ($phone_matches[0] $match) {     //do $match } 

but you're actually trying accomplish, there's no need preg_match_all @ all. simple one-line preg_replace trick:

$check = preg_replace('/[(]*\d{3}[)]*\s*[.\- ]*\d{3}[.\- ]*\d{4}/', '<span class="hide">$0</span><span class="show">show phone</span>', $check);
