Php search for specific links and append the url after them -

i have string following patterns

$mystring="bla <a href="website.com"></a>"; 

with few more links , other html tags.

i want use php function to:

• search href tags contain specific word. in case, word website.com.

• append text link same url every occurrence.

example:

<a href="website.com?bla"></a> 

should become to:

<a href="website.com?bla"></a><br><a href="website.com?bla">new link here</a> 

and same goes rest links.

how go doing this?

first of all, should iterate around occurrences, using strpos method, using lastpos offset. insert string/new link, after finding closing

$needle = "website.com?"; // word find $endlink = "</a>" $lastpos = 0; $str_to_insert = "<br><a href=\"website.com?bla\">new link here</a>" // text append  while (($lastpos = strpos($mystring, $needle, $lastpos))!== false) {     //position after finding string is: occurrence + string length     $lastpos = $lastpos + strlen($needle);     //finding end of link (to append there)     $writepos = strpos($mystring, $endlink, $lastpos);     //appending string , updating $mystring     $mystring = substr_replace($mystring, $str_to_insert, $writepos, strlen($endlink);     //add appended string lastpos, avoid searching     $lastpos = $writepos + strlen($str_to_insert)  } 

edit

making $str_to_insert dynamic:

while (($lastpos = strpos($mystring, $needle, $lastpos))!== false) {         $str_to_insert = substr($mystring, $lastpos, len($needle)         //position after finding string is: occurrence + string length         $lastpos = $lastpos + strlen($needle);         // ... rest keeps same }
