note 58639 added to ref.var

On rare occasions, you may need to retrieve a variable name as a string. This handy little function retreives the variable name: var_name($my_var) will give 'my_var'. <?php function var_name (&$iVar) { foreach($GLOBALS as $k=>$v) $GLOBALS_0[$k] = $v; $iVar_Save = $iVar; $iVar = ($iVar===1)?0:1; $aDiff_Keys = array_keys (array_diff_assoc ($GLOBALS_0, $GLOBALS)); $iVar = $iVar_Save; return ($aDiff_Keys[0]); } $abcde = 1; echo 'var $<b>',var_name ($abcde),'</b> = ',var_dump($abcde),'<br><hr>'; $fghij = 4; echo 'var $<b>',var_name ($fghij),'</b> = ',var_dump($fghij),'<br><hr>'; $klmno = 'qwerty'; echo 'var $<b>',var_name ($klmno),'</b> = ',var_dump($klmno),'<br><hr>'; $pqrst = array('aa'=>'11','bb'=>'22',3); echo 'var $<b>',var_name ($pqrst),'</b> = ',var_dump($pqrst),'<br><hr>'; $uvwxy = &$fghij; echo 'var $<b>',var_name ($uvwxy),'</b> = ',var_dump($uvwxy),'<br><hr>'; ?> ---- Manual Page -- http://www.php.net/manual/en/ref.var.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58639 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58639&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58639&report=yes Search -- http://master.php.net/manage/user-notes.php
