note 76180 added to function.str-replace

In case anyone doesn't know, Erik's code will not work. Besides the major syntax flaws, the count parameter returns how many replacements were made, it DOES NOT limit how many are made. If you really need to replace every other occurrence, this DOES work: <?php function str_replace_every_other($needle, $replace, $haystack, &$count=null, $replace_first=true) { $count = 0; $offset = strpos($haystack, $needle); //If we don't replace the first, go ahead and skip it if (!$replace_first) { $offset += strlen($needle); $offset = strpos($haystack, $needle, $offset); } while ($offset !== false) { $haystack = substr_replace($haystack, $replace, $offset, strlen($needle)); $count++; $offset += strlen($replace); $offset = strpos($haystack, $needle, $offset); if ($offset !== false) { $offset += strlen($needle); $offset = strpos($haystack, $needle, $offset); } } return $haystack; } //Use it like this: $str = "one two one two one two"; echo str_replace_every_other('one', 'two', $str, $count).'<br />'; //two two one two two two echo str_replace_every_other('one', 'two', $str, $count, false).'<br />'; //one two two two one two ?> I added the last option ($replace_first) to let you replace the odd occurrences (true, default) or the evens (false). ---- Server IP: 69.147.83.197 Probable Submitter: 63.225.219.62 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/76180 Del: integrated -- https://master.php.net/note/delete/76180/integrated Del: useless -- https://master.php.net/note/delete/76180/useless Del: bad code -- https://master.php.net/note/delete/76180/bad+code Del: spam -- https://master.php.net/note/delete/76180/spam Del: non-english -- https://master.php.net/note/delete/76180/non-english Del: in docs -- https://master.php.net/note/delete/76180/in+docs Del: other reasons-- https://master.php.net/note/delete/76180 Reject -- https://master.php.net/note/reject/76180 Search -- https://master.php.net/manage/user-notes.php
