note 49205 added to function.addcslashes

If you are using addcslashes() to encode text which is to later be decoded back to it's original form, you MUST specify the backslash (\) character in charlist! Example: <?php $originaltext = 'This text does NOT contain \\n a new-line!'; $encoded = addcslashes($originaltext, '\\'); $decoded = stripcslashes($encoded); //$decoded now contains a copy of $originaltext with perfect integrity echo $decoded; //Display the sentence with it's literal \n intact ?> If the '\\' was not specified in addcslashes(), any literal \n (or other C-style special character) sequences in $originaltext would pass through un-encoded, but then be decoded into control characters by stripcslashes() and the data would lose it's integrity through the encode-decode transaction. ---- Manual Page -- http://www.php.net/manual/en/function.addcslashes.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49205 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49205&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49205&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49205&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49205&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49205&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49205&report=yes Search -- http://master.php.net/manage/user-notes.php
