You can use unset($arr[3]);. It will delete that array index. Whenever you want to delete an array value, you can use PHP unset() method.

As you were asked into your comment: basically i just want to remove all index that have "X**X" this pattern digit 'x' digit

Here is the code that you can use:

    $arr = array("LR-153-TKW", "Klaten", "Rectangular", "12x135x97", "xxxx");
    $pattern_matched_array = preg_grep("/^[0-9]+x[0-9]+x[0-9]*/", $arr);
    if(count($pattern_matched_array) > 0)
    {
        foreach($pattern_matched_array as $key => $value)
        {
            unset($arr[$key]);
        }
    }
    print_r($arr);

Use unset, to find it you can do this:

for($i = 0; $i < count($array); $i++){
    if($i == "12x135x97"){
        unset($array[i]);
        break;
    }
}

Unless you know the key, in which case you can do: 

unset($array[3]);

its not the most time efficient if you array is thousands of items long, but for this job it will suffice.

To turn it into a method, would make for better coding.

function removeItem($item){
    for($i = 0; $i < count($array); $i++){
        if($i == $item){
            unset($array[i]);
            break;
        }
    }
    return $array;
}

and call it like:

removeItem("12x135x97");

You have many options: if you know the array key then you can do this

unset($arrayName[3]);

or if it's always at the end of your array

array_pop($arrayName);

this will remove the last value out of your array

PHP has unset() function. You can use it for deleting a variable or index of array.

unset($your_var[3]);

See http://php.net/manual/en/function.unset.php
