Filter values from array in PHP

Question

I would like to filter the values of [name] from the array below.

Array
(
    [0] => Array
        (
            [name] => tags1
        )

    [1] => Array
        (
            [name] => tag2
        )

    [2] => Array
        (
            [name] => tag3
        )
)

How to do that?

PHP version +5.5 ? -> array_column() OR look in the profile of @AbraCadaver for a workaround implementation for php versions under 5.5 :D — Rizier123

If you just want to get all of the name values in an array:

PHP >= 5.5.0 needed for array_column() or use the PHP Implementation of array_column()

$names = array_column($array, 'name');

Thanks, I keep that in mind. Unfortunately, my server runs only 5.3 at the moment.

If you are looking for simple solution you can use foreach loop:

foreach($array as $row){
    echo $row['name'];
}

That's awesome, thanks. How can I turn the result from the loop into a new array? (all found ['name'] values in one array)

instead of echo write $result[] = $row['name']. It will append new value to the $result array. Of course before foreach put $result = array();

I think you want to be able to filter your output array by a particular name? This function will return an array that only has the subarray that has the matching 'name'

function getspecificname($thisarray,$thisname){
    $arraytoreturn=array();
    foreach($thisarray as $onearray){
        if($onearray['name']==$thisname){
            $arraytoreturn[]=$onearray;
        }
    }
    return $arraytoreturn;
}

$myfilteredarray=getspecificname($yourarray,'tag2');
