preg_replace

[Thomas Schandl]

Hi!

When replacing with preg_replace e. g.:

$Month_Strings = array('/Jan/','/Feb/','/Mar/','/Apr/','/May/','/Jun/',
'/Jul/','/Aug/','/Sep/','/Oct/','/Nov/','/Dec/');
$Month_Numbers = array('1','2',' 3','4','5','6',
'7','8','9','10 ','11','12');

$month_number = preg_replace($M onth_Strings, $Month_Numbers, $month, 1);


How can I get an error message if nothing was replaced?

Bye,
Thomas

Take a look into the preg_replace_ca llback function... of possibly use
preg_match_all first.

do a strlen on the result, and if less than 3 chars, it is an error
(caution: NOT a general solution, but works in your case).
