PHP to get enum/set values from mysql field

This function returns an array with the elements allowed in a ENUM or SET mysql field. This can be usefull if you’re making some automation and need to retrieve those values without writing them in your code:

function set_and_enum_values( $table , $field ){
	$query = "SHOW COLUMNS FROM `$table` LIKE '$field'";
	$result = mysql_query( $query ) or die( 'Error getting Enum/Set field ' . mysql_error() );
	$row = mysql_fetch_array($result);
	if(stripos(".".$row[1],"enum(") > 0) $row[1]=str_replace("enum('","",$row[1]);
		else $row[1]=str_replace("set('","",$row[1]);
	$ar = split("\n",$row[1]);
	for ($i=0;$i<count($ar);$i++) $arOut[str_replace("''","'",$ar[$i])]=str_replace("''","'",$ar[$i]);
	return $arOut ;

    You might be wanting to escape those variables… you know, so someone doesn’t try to get the enum of bobby'; DROP TABLE users;

    Line 9 uses the now deprecated split function. Recommend replacing it with explode.

    I’m wondering if we can get the updated version using the explode syntax. Also, as I’m just starting server side I’d like to know if the function is placed in the get/post statement or can it be added to something like phpMyAdmin as a standard function which actually filters the get/post queries? Best regards, Heinz Stapff

    Just read similar function for ENUM fields on that uses a regexpression and the split syntax but I’m in the dark as to wheather the $field has to be specified or the function loops through the whole row of fields and outputs the split info for each enum or set field? Also a complete index of rows as the $row = mysql_fetch_array($result); implies? The topic on phpfreaks is They also showed the echo statement for producing the results on select options but I’m still not sure where to put the function, in the .php? file?
