php REGEX help replace text inside of specific symbols -


i have string 1 being 

[my_name] , being <my_name>

i need use regex search text within [ ] , < > brackets , replace bob

i provide sample code don't know begin. appreciated

so far iv tried this

  $regex = [\^[*\]]

thinking inside [] tags

i imagine following should work:

preg_replace('/([\[<])[^\]>]+([\]>])/', "$1bob$2", $str);

explanation of regex:

([\[<]) -> first capturing group. here describe starting characters using            character class contains [ , < (the [ escaped \[) [^\]>]+ -> stuff comes between [ , ] or < , >.            character class says want character other ] or >.            ] escaped \]. ([\]>]) -> second capturing group. we describe ending characters using            character class. similar first capturing group.

the replacement pattern uses backreferences refer capturing groups. $1 stands first capturing-group can contain either [ or <. second capturing-group represented $2, can contain either ] or >.
