Here's the situations: I have 2 arrays, eg:
$a=array('a','b','c','d');
$b=array('1','b','c','e');
I want to produce 2 arrays with result:
$c=array('a','d');//only element appeared on $a
$d=array('1','e');//only element appeared on $b
Do you have a clever solution?
$c = array_diff($a, $b);
$d = array_diff($b, $a);
Sorry, my bad. It turn out a was giving the wrong array in my test.
simple array_diff solved the problem:
$c = array_diff($a, $b);
$d = array_diff($b, $a);
Try using the array_diff() function:
array_diff(array1,array2,array3...)
eg:
<?php
$a1=array(0=>"Cat",1=>"Dog",2=>"Horse");
$a2=array(3=>"Horse",4=>"Dog",5=>"Fish");
print_r(array_diff($a1,$a2));
?>
Output:
Array ( [0] => Cat )
