In PHP string I want extract ID and replace with name player -

i extract #id1234 , use function replace name in link form.

the id number dynamic.

so from

$string = 'hello #id1234 , rest of text'; 

to

$string = 'hello , <a href="#">john</a> , rest of text'; 

i need function name , sort link. okay code not sure how extact #id1234 convert player number 1234.

the player number can put anyway easy , fast extract ideas welcome ie {1234}

assuming function get_name($id) returns name of user, try:

preg_match_all('/\d+/', $string, $id); $name = get_name($id) preg_replace("/#id[0-9]*/", "<a href='/whatever_url?id=".$id."'>".$name."</a>", $string);
