custom array_flip function . it will flip array in one dimensional as array_flip do


function ArrayFlip($array){
	$tempd=array();
	foreach($array as $key=>$value){
		$tempd[$value]=$key;
	}
	return $tempd;
}
$array=array("A"=>"a");
$d=ArrayFlip($a);

its good alternative of array_flip PHP function .
ArrayFlip replace the common entry with last one . if you want to preserve the unique entry than following function will help


 function ArrayFlip($a){
	$tempd=array();
	foreach($a as $key=>$value){
		if(isset($tempd[$value]))
		$tempd[$value]=$key;
		else 
		$tempd[$value.rand(1,100)]=$key;
	
	}
	return $tempd;
}

for the unique value i changed it to by adding random number . you can do you way to make it visible


		$tempd[$value.rand(1,100)]=$key;

change this code in function ArrayFlip
