note 46580 added to function.preg-replace

this example was incorrectly provided by a user: $string="My name is [0]"; $names=array("Bill","Bob","Joe"); $string = preg_replace("/\[(\d+)\]/",$names[(int) ${1}],$string); echo $string; output should be "My name is Bill" output works with the above case only. $string = '[1]' does NOT output Bob. these also do NOT work: $names[${1}] $names[\${1}] $names[$1] $names[\$1] $names[\\$1] only these seems to work: $names[\1] $names[\\1] ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46580 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+46580&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+46580&report=yes Search -- http://master.php.net/manage/user-notes.php
