I want to extract parts of string that have a dollar sign followed by digits, and
- either have a space or = in front of $ and
- space or end of string after digits
expression in the code below works fine except it doesn’t extract $7. What do I need to change to get
" $1 "
“=$6 "
" $7”
$var = “sometext $1 sometext $2and sometext$4 and sometext($3) sometext=$6 sometext= $7”;
preg_match_all(‘/[=\s]{1}\$\d+[\s$\z]{1}/’,$var,$matches);
var_dump($matches);
Thanks for your help.
