Req #10429 [Opn]: Add options for start/end strings for substr()

Edit report at https://bugs.php.net/bug.php?id=10429&edit=1 ID: 10429 Updated by: requinix@php.net Reported by: sbergmann@php.net Summary: Add options for start/end strings for substr() Status: Open Type: Feature/Change Request Package: Strings related Operating System: * PHP Version: * Block user comment: N Private report: N New Comment: Changing a function as important as substr could very well need an RFC. There is a problem to confront first: substr("string", "0", "5") is ambiguous. On the other hand a brand new function, maybe named according to the substr_* pattern already in place, wouldn't be that difficult and shouldn't require an RFC... Compare with MySQL's SUBSTRING_INDEX function. http://dev.mysql.com/doc/refman/5.6/en/string-functions.html#function_substring-index Previous Comments: ------------------------------------------------------------------------ [2015-01-15 13:47:19] ppasindud at gmail dot com Wouldn't this be a Feature/Change Request and require RFC ------------------------------------------------------------------------ [2001-04-21 05:09:31] sbergmann@php.net I am currently using the following PHP Code to get a substring from a string, that is delimited by two given strings, $start and $end: function my_substr($start, $end, &$string) { $start = preg_quote($start); $end = preg_quote($end); preg_match("#$start(.*?)$end#", $string, $result); return $result[1]; } It would be great if PHP's substr() function could handle operations like this, by changing its signature accordingly, maybe to string substr (string string, mixed start [, mixed end]) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=10429&edit=1
