Array check if object key has same value-CodePudding

I want to push values from old array to a new array. when pushing I am checking the object value is already exist or not. the value should be pushed only when the same object value is not exist in new array. here is my code.

$sorted_array = array();

foreach ($data as $nkey => $value) {
        if (count($sorted_array) > 0) {
            dd($sorted_array[$nkey]);
            if ($sorted_array[$nkey]['store'] != $value['store']) {
                array_push($sorted_array, $value);
            }
        }
        else{
            array_push($sorted_array, $value);
        }
    }

CodePudding user response：

If I understood correctly, you can easily handle it using the in_array function:

$sorted_array = array();

foreach ($data as $nkey => $value) {
        if ( !in_array($value, $sorted_array) ) {
            array_push($sorted_array, $value);
        }
}

in_array function return boolean value. In my code, if the $value parameter is not in the $sorted_array, then it will pushed. Otherwise operation is not performed.

array_push in this case is wrong. Try this code:

foreach ($data as $nkey => $value) {
    if (count($sorted_array) > 0) {
        if ($sorted_array[$nkey]['store'] != $value['store']) {
            $sorted_array[$nkey] = $value;
        }
    }
}

Hope can help you
