php str replace anything but <value here>

[jman11]

hey i have a str replace function that looks for key and replaces with value. im looking for how to do:

$arr = array("\b{anything but 0 here, so it could be a-z,A-Z,1-9 but i dont remember how}" => "<b>");

basically i want to have the array key be \b+anything but 0

Use the perl compatible regular expression [php.net] engine. Put the zero in a character class and negate it.

\b[^0]+
