How to remove element of array in php?

Question

I have array:

Arrays:

Array
(
[0] => Array
    (
        [name] => point
        [visibility] => 
    )

[1] => Array
    (
        [name] => php_first_table
        [visibility] => 1
    )

[2] => Array
    (
        [name] => ohz
        [visibility] => 1
    )

)

Now i want to find and remove element with name=ohz:

    for($i=0;$i<count($arrays);$i++){
        if(array_search("ohz",$arrays[$i])){
            unset($arrays[$i]);
        }
    }
    print_r($arrays);

output:

Array
(
[0] => Array
    (
        [name] => point
        [visibility] => 
    )

[2] => Array
    (
        [name] => ohz
        [visibility] => 1
    )

)

Why php_first_table not ohz was deleted?

The code should work fine. Can you provide a complete program that has this behavior? — Jon

In PHP there is array_filter() for this:

$arrays = array_filter($arrays, function($item)
{
   return !(array_key_exists('name', $item) && $item['name']=='ohz');
});

@Jon I'll check now, thank you (I'm messing this with something else?)

To be fair, changing the internal array pointer yourself (e.g. by calling reset inside the loop) is problematic. But deleting items is OK.

@Jon You're correct, I missed array pointer (which has nothing to do with this case, obviously). Sorry, better to take rest.. Thanks again!

Try like

for($i=0;$i<count($arrays);$i++){
    if($arrays[$i]['name'] == 'ohz')){
        unset($arrays[$i]);
    }
}
print_r($arrays);

Try this:

<?php
        $arr_var  = Array
        (
            Array('name' => 'point','visibility' => ''),
            Array('name' => 'php_first_table', 'visibility' => 1),
            Array('name' => 'ohz', 'visibility' => 1)
        );

        foreach($arr_var as $key => $value)
        {
            if($value['name'] == 'ohz'){
                unset($arr_var[$key]);
            }
        }

        echo '<pre>';
        print_r($arr_var);
        ?>

working fine.

Thanks
