note 93193 added to function.preg-match-all

the example given is skipping an array entry. Should be: <?php // The \\2 is an example of backreferencing. This tells pcre that // it must match the second set of parentheses in the regular expression // itself, which would be the ([\w]+) in this case. The extra backslash is // required because the string is in double quotes. $html = "<b>bold text</b><a href=howdy.html>click me</a>"; preg_match_all("/(<([\w]+)[^>]*>)(.*?)(<\/\\2>)/", $html, $matches, PREG_SET_ORDER); foreach ($matches as $val) { echo "matched: " . $val[0] . "\n"; echo "part 1: " . $val[1] . "\n"; echo "part 2: " . $val[2] . "\n"; echo "part 3: " . $val[3] . "\n\n"; } ?> instead of: <?php // The \\2 is an example of backreferencing. This tells pcre that // it must match the second set of parentheses in the regular expression // itself, which would be the ([\w]+) in this case. The extra backslash is // required because the string is in double quotes. $html = "<b>bold text</b><a href=howdy.html>click me</a>"; preg_match_all("/(<([\w]+)[^>]*>)(.*?)(<\/\\2>)/", $html, $matches, PREG_SET_ORDER); foreach ($matches as $val) { echo "matched: " . $val[0] . "\n"; echo "part 1: " . $val[1] . "\n"; echo "part 2: " . $val[3] . "\n"; echo "part 3: " . $val[4] . "\n\n"; } ?> ---- Server IP: 216.235.13.26 Probable Submitter: 64.228.81.81 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match-all.php Edit -- https://master.php.net/note/edit/93193 Del: integrated -- https://master.php.net/note/delete/93193/integrated Del: useless -- https://master.php.net/note/delete/93193/useless Del: bad code -- https://master.php.net/note/delete/93193/bad+code Del: spam -- https://master.php.net/note/delete/93193/spam Del: non-english -- https://master.php.net/note/delete/93193/non-english Del: in docs -- https://master.php.net/note/delete/93193/in+docs Del: other reasons-- https://master.php.net/note/delete/93193 Reject -- https://master.php.net/note/reject/93193 Search -- https://master.php.net/manage/user-notes.php
