Preg_match explained - Regex Help |
[eluser]richzilla[/eluser]
Hi all, Im having a bit of trouble getting my head around preg_match as im trying to write some customised validation functions.Basically im trying to validate a price, and what ive come up with so far is this: Code: [0-9]+(\.|\,)[0-9][0-9] However, although that works, as far as i can see, the preg match function returns true if that is matched anywhere in a string, so you could enter complete rubbish: Code: aasosdoiasoi10.00idfgisdfgisudfgisdf would still technically be correct. Is there any php function i can use to make sure my string exactly matches my regular expression? any help would be appreciated. Thanks

use ^ for the start of a line, and $ for the end of a line
