note 42787 added to pcre.pattern.syntax

In addition to the meta-characters mentioned above, there can be another special character in a regular expression: the delimiter you use to start and end your expression. Often people use the / character for this. For example, if you wanted to search for text surrounded by opening and closing tags like'<TD>SELL</TD>' and replace it with nothing (erase it), you might be tempted to use a regex like this: <?php $myNewText = preg_replace('/<TD>SELL</TD>/', "", $myText); ?> This does not work properly. As mentioned in the Introduction at the top of http://www.php.net/manual/en/ref.pcre.php, if the delimiter appears in the middle of your regular expression, then you must put a \ character before it. So this DOES work: <?php $myNewText = preg_replace('/<TD>SELL<\/TD>/', "", $myText); ?> That same Introduction also mentions that you can start and end your expression with characters other than the usual /. Because there are no % characters in the middle of my expression above, I might prefer to use the following: <?php $myNewText = preg_replace('%<TD>SELL</TD>%', "", $myText); ?> That also works correctly, and I did not need a \ before the /. ---- Manual Page -- http://www.php.net/manual/en/pcre.pattern.syntax.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42787 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42787&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42787&report=yes Search -- http://master.php.net/manage/user-notes.php
