Hi There have a nice day is there anybody knows how to kill,exit or break if the array is empty;

i try this

$arr = array();

if(!array_key_exists($arr)) {
break; // or Exit or Die 🙂
}

All these should work:

$arr = array(); 

if(!array_key_exists($arr)) { 
exit;  

}

$arr = array(); 

if(!array_key_exists($arr)) { 
die();  

}

$arr = array(); 

if(!array_key_exists($arr)) { 
die("Message Here");  

}

if(count($arr)==0) break;


if(count($arr)==0) exit;


if(count($arr)==0) die;


if(empty($arr)) break; // Look! A function that tests if a variable is empty!


if(empty($arr)) exit;


if(empty($arr)) die;

These is my codes and i want to kill my script if the array is Null or not exist;

if ($POST['CheckAll']) {
$arr = $POST['list'];
// echo "array : ".$arr."<br>";

	if(!array_key_exists($arr)) {  
		die();   
		 if(array($arr)) {
			$_SESSION['list'] = $_POST['list'];
			$cityNum = $_SESSION['list'];

			if (empty($cityNum)) {
				break;
			}

			$array = array($cityNum); 
			$string = serialize($array); 
			$_SESSION[strSession] = $string	

		   ?>
		   <SCRIPT LANGUAGE="JavaScript">
				   onLoad=window.open('craigMain_2a.php?arr=<? echo $_SESSION[strSession];?>','mywindow5','width=600,height=400,toolbar=no, location=no,directories=no,status=yes,menubar=no,scrollbars=yes,copyhistory=yes, resizable=no');
		   </script>
		   <? 	   
	   }
   }

}

if(!array_key_exists($arr)) {

die();

Weedpacket gave the answer. "empty($array)" will return true if the array has not been defined, or if it has been defined but has no elements.

Don't forget your closing curly brace. Seems like you have a never ending if(empty($arr)){ argument. You have:

if(!array_key_exists($arr)){
die();

perhaps, you should change it to:

if(empty($arr)){
die("Message");
}
