I've got this bit of code which finds occurrences of a string in a larger string. The following example works fine, it's looking for "Project Management"
preg_match_all("/\bProject Management\b/i", $content, $match_array);
However, if I want to search for say "c++" the following doesn't work:
preg_match_all("/\bc++\b/i", $content, $match_array);
I understand you have to escape the plus sign, so I have tried the following which also does not work:
preg_match_all("/\bc\+\+\b/i", $content, $match_array);
How can I search for "c++" using this bit of regex?
