Remove item from php array by passing value

I have a php array like this

Array
(
    [0] => WVSE1P
    [1] => WVSE1MA
    [2] =开发者_Python百科> WVSEU1Y
    [3] => WVSEUP
)

how do i remove a particular entry in it by passing the value?

below is the code i tried:

$array = $items; //array is items

foreach($array as $key => $value) 
{

$val= 'WVSE1P'; //item to remove
if ($value == $val) unset($array[$key]);

}

but it doesn't seem to work.

You should probably use array_splice instead of unset so that your array indexes match up correctly after unsetting.

How about this?:

$val = 'WVSE1P';
$items = array_splice($items, array_search($val), 1);

This method removes any values in the specified array without any looping: Example:

$array = Array("blue", "orange", "red");

$array = array_diff($array, array("blue")); // blue will be removed

//optionally you can realign the elements:

$array = array_values($array);

The reason yours may not work is because you are containing it inside a loop which does not control the array object.

Unsetting array items while iterating over that array may cause some unexpected behaviour some times. Here's another solution:

$flipped = array_flip($array);
unset($flipped['WVSE1P']);
$array = array_flip($flipped);

This should work in this case. Just make sure, that all values are unique within the array.
