Delete some data from Array in php

Question

I want to delete some data from an array in PHP. Here is the array:

array(4) {
    [0]=> array(1) { ["image"]=> string(20) "w85YrKChBGTZ9fQS.jpg" }
    [1]=> array(1) { ["image"]=> string(20) "3buahEs6rRWFdYez.jpg" }
    [2]=> array(1) { ["image"]=> string(20) "gYPtDrx3sFzkVENB.jpg" }
    [3]=> array(1) { ["image"]=> string(20) "JE3rodDvs6521cFm.jpg" }
} 

Here is my method and where I am deleting:

public function deleteImage(){
    foreach (getCarImages() as $array){
        //var_dump($array).'<br>';
        $index = array_search('w85YrKChBGTZ9fQS.jpg',$array);
        if($index !== FALSE){
            var_dump($index).'<br>';
            unset($array[$index]);
        }else{
            echo '<br>else here';
        }
    }
}

And here is the result of deleteImage()

string(5) "image"

else

here

here

I am confused. How can I delete a nested array from the main array.

Answer 1

If you need to delete a whole subarray from array, then use array_flter function:

public function deleteImage(){
    return array_filter(getCarImages(), function ($v) {
        return $v['image'] != 'w85YrKChBGTZ9fQS.jpg';
    });
}

Update: Anonymous function doesn't know about $imageName variable. You have to use it:

public function deleteImage($imageName = null) 
{ 
    $myarray = array_filter(
        getCarImages(), 
        function ($v) use ($imageName) { return $v['image'] != $imageName; }
    );
}

Answer 2

You can trans the images as a reference to the function.

public function deleteImage(&$images){
    foreach ($images as $k => $array){
        //var_dump($array).'<br>';
        $index = array_search('w85YrKChBGTZ9fQS.jpg',$array);
        if($index !== FALSE){
            var_dump($index).'<br>';
            unset($images[$k]);
        }else{
            echo '<br>else here';
        }
    }
}
