Re: regex question

Murry's solution here is ideal since it only captures the single occurrence. Since I want to use it for a preg_replace(), it is perfect. A couple of folks sent this pattern [^@]@[^@]; but, it doesn't work because I then have to remove the unwanted caracters on either side. All it says is [not @]@[not@] but, it captures the 2 characters on each side. Murry's solution (?<!@)@(?!@) is good since it only captures the "@" Thanks everyone....

What pattern can I use to match ONLY single occurrences of a character in a string. e.g., "Some text @ and some mo@@re and mor@e, etc @@@. I only want the two occurrences with a single occurrence of "@". @{1} doesn't work; there are 4 matches. Thanks....

Please ignore my last email re: your question. I realized that the negation of the range containing the "@" would end up capturing unwanted characters. As an alternative, try the following: preg_match_all('/(?<!@)@(?!@)/','Some @ text with the @t sym@@bol @@@@ ', $thing, PREG_OFFSET_CAPTURE); print_r($thing); Hope that's a little more relevant to your question.
