delete entire row from array php

I am trying to delete a row from a php 2d array. Here is my following code. It currently does not work because it leaves a blank space in the array instead of completely removing the row and restructuring the array to not include the row at all.

Let's say I have an array like this:

$array[0] = "ball";
$array[1] = "bat";
$array[2] = "glove";
$array[3] = "referee";
$array[4] = "strike";
$array[5] = "home run";

Now, let's say I want to get rid of [3] but move the next values up, automatically, into 3,4.

For example,

$array[0] = "ball";
$array[1] = "bat";
$array[2] = "glove";
$array[3] = "strike";
$array[4] = "home run";

How do I do this in php with my attached code
if ($cart) {
	$tempcart = array();
		foreach ($cart as $line) {
			if ($line['id'] == $id && $line['style'] == $style && $line['color'] == $color && $line['size'] == $size) {
				unset($line);
			}
		$tempcart[] = $line;
		}
	}
	$cart = $tempcart;

Try this.

unset ($array[3]);
array_unshift ($array, array_shift ($array));

You almost did it.
if ($cart) {
	$tempcart = array();
	foreach ($cart as $line) {
		if (!($line['id'] == $id && $line['style'] == $style && $line['color'] == $color && $line['size'] == $size)) {
			$tempcart[] = $line;
		}
	}
}
$cart = $tempcart;

Or this works too.
foreach ($cart as $key=>$line) {
	if ($line['id'] == $id && $line['style'] == $style && $line['color'] == $color && $line['size'] == $size) {
		unset($cart[$key]);
	}
}
$cart = array_merge($cart);

Ok I dont think I described my array properly, here is the structure and what result I want

Here is the original array

Array (
    [0] => Array (
        [id] => 1
        [style] => T-Shirt
        [color] => Black
        [size] => XL
        [qty] => 1
    )
    [1] => Array (
        [id] => 91
        [style] => T-Shirt
        [color] => Black
        [size] => XL
        [qty] => 1
    )
)

Then I want it to be

Array (
    [0] => Array (
        [id] => 1
        [style] => T-Shirt
        [color] => Black
        [size] => XL
        [qty] => 1
    )
)
