Question

For example i have an array like this:

  $test= array("0" => "412", "1" => "2"); 

I would like to delete the element if its = 2

 $delete=2;
 for($j=0;$j<$dbj;$j++) {
     if (in_array($delete, $test)) {    
         unset($test[$j]);
     }
 }
 print_r($test);

But with this, unfortunatelly the array will empty…
How can i delete an exact element from the array?
Thank you

In the loop you’re running the test condition is true because $delete exists in the array. So in each iteration its deleting the current element until $delete no longer exists in $test. Try this instead. It runs through the elements of the array (assuming $dbj is the number of elements in $delete) and if that element equals $delete it removes it.

$delete=2;
for($j=0;$j<$dbj;$j++) {
    if ($test[$j]==$delete)) {  
        unset($test[$j]);
    }
}
print_r($test);
