note 74037 added to function.preg-replace

Be aware that when using the "/u" modifier, if your input text contains any bad UTF-8 code sequences, then preg_replace will return an empty string, regardless of whether there were any matches. This is due to the PCRE library returning an error code if the string contains bad UTF-8. ---- Server IP: 64.71.164.2 Probable Submitter: 192.216.254.5 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/74037 Del: integrated -- https://master.php.net/note/delete/74037/integrated Del: useless -- https://master.php.net/note/delete/74037/useless Del: bad code -- https://master.php.net/note/delete/74037/bad+code Del: spam -- https://master.php.net/note/delete/74037/spam Del: non-english -- https://master.php.net/note/delete/74037/non-english Del: in docs -- https://master.php.net/note/delete/74037/in+docs Del: other reasons-- https://master.php.net/note/delete/74037 Reject -- https://master.php.net/note/reject/74037 Search -- https://master.php.net/manage/user-notes.php
