php - Regex - replace all the 11 digit numbers with link -


i trying replace 11 digit numbers links.

right preg_match_all not returning matches strings, returning last matched one. preg_replace returning single 11 digit number link. 

   //string numbers replaced links.          $test ="test these numbers 20150423011 20150423012 sdf sdfsdf sdfs fsdf sdfs dfsdfsd 20150423014 fsdf";      $s = preg_match_all("/^((?:.*?)(20\d{9})(?:.*?))+$/",$test,$matches);      foreach($matches[2] $m){     $replacements[] = "<a href=''>".$m."</a>";     $patterns[] = "/^((?:.*?)(20\d{9})(?:.*?))+$/";      }     $final = preg_replace($patterns, $replacements,$test);     echo $final; //right gives out last matched number link

i'm not sure if understood question, assume want wrap numbers starting 20 using <a href....

for case, can use regex:

(20\d{9})

working demo

you can use code:

$re = "/(20\\d{9})/";  $str = "test these numbers 20150423011 20150423012 sdf sdfsdf sdfs fsdf sdfs dfsdfsd 20150423014 fsdf";  $subst = "<a href=''>$1</a>";   $result = preg_replace($re, $subst, $str);

your resulting string be:

test these numbers <a href=''>20150423011</a> <a href=''>20150423012</a> sdf sdfsdf sdfs fsdf sdfs dfsdfsd <a href=''>20150423014</a> fsdf
