note 64455 added to function.eregi-replace

Here's a nice case-insensitive highlight function that ignores any regular expression characters and highlights a word and leaves it in whatever case it was before: <? function highlight($word, $subject) { $regex_chars = '\.+?(){}[]^$'; for ($i=0; $i<strlen($regex_chars); $i++) { $char = substr($regex_chars, $i, 1); $word = str_replace($char, '\\'.$char, $word); } $word = '(.*)('.$word.')(.*)'; return eregi_replace($word, '\1<span class="highlight">\2</span>\3', $subject); } ?> ---- Server IP: 216.194.113.175 Probable Submitter: 71.39.3.166 ---- X-Spam-Status: No, hits=3.3 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, HTML_MESSAGE autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.eregi-replace.php Edit -- http://master.php.net/note/edit/64455 Del: integrated -- http://master.php.net/note/delete/64455/integrated Del: useless -- http://master.php.net/note/delete/64455/useless Del: bad code -- http://master.php.net/note/delete/64455/bad+code Del: spam -- http://master.php.net/note/delete/64455/spam Del: non-english -- http://master.php.net/note/delete/64455/non-english Del: in docs -- http://master.php.net/note/delete/64455/in+docs Del: other reasons-- http://master.php.net/note/delete/64455 Reject -- http://master.php.net/note/reject/64455 Search -- http://master.php.net/manage/user-notes.php
