Remove Specific key value pair from PHP array

Question

I have two key value pair arrays, one is the original, the other an array of key value pairs that need to be removed. I need to remove a specific combination, ie $removeArray would contain:

Array([Word] => 78)

I've tried:

foreach($removeArray as $key => $value){unset($originalArray[$key][$value]);}

This doesn't work at all. I need to remove based off an exact key value pair match.

EDIT:

Original

Array ( [distribution] => 25 [watch] => 25 [electricity] => 25 [timepiece] => 8 [wristwatch] => 25 [energy] => 8 [transmission] => 8 [clock] => 16 )

Remove

Array ( [timepiece] => 8 [energy] => 8 [watch] => 17 )

Result

Array ( [distribution] => 25 [watch] => 25 [electricity] => 25 [wristwatch] => 25  [transmission] => 8 [clock] => 16 )

NOTE:

[watch] => 25 is not affected, because it is not equal to [watch] => 17

Can you post two array and expected result ?

You can use array_diff_assoc() for that, that compares both the values and the keys:

$result = array_diff_assoc($original, $to_remove);

Example code:

$removeArray = array(
    'word'=>45,
    'number'=>112,
    'sign'=>2167
);

$originalArray = array(
    'lorem'=>2343,
    'ipsum'=>433,
    'word'=>78,
    'number'=>112,
    'sign'=>2167
);

$result = array_diff_assoc($originalArray, $removeArray);

Result:

Array
(
    [lorem] => 2343
    [ipsum] => 433
    [word] => 78
)

try this

foreach($removeArray as $key => $value){
    if($value==$originalArray[$key])
        unset($originalArray[$key]);
}

You can check like:

if($originalArray[$key] == "78" && $key = "Word") {
unset($originalArray[$key]);
}
