I have two arrays:
$array = new Array('id'=>1, 'name'=>'Peter', 'sex'=>'male', 'age'=>25);
$excludes = new Array('sex', 'age');
I want to get the following result:
$array = new Array('id'=>1, 'name'=>'Peter');
The items whose keys are found in the array $excludes are removed.
How can I achieve this conveniently?
Simply with array_diff_key and array_flip functions:
// $arr is your initial array (besides, don't give `$array` name to arrays)
$result = array_diff_key($arr, array_flip($excludes));
print_r($result);
The output:
Array
(
[id] => 1
[name] => Peter
)
function removeExcludesFromArray($input,$expludes) {
$newArray = array(); // Create a new empty array
foreach($array as $inputKey => $inputElement) { // loop your original array
if(!array_key_exists($inputKey,$excludes)) { // check if key exists
$newArray[$inputKey] = $inputElement; // add on demand
}
}
return $newArray; // return the result
}
// Call the function
$array = removeExcludesFromArray($array,$excludes);
