如何使用PHP将数组分解为另一个数组而不是子数组？

Question

Is there any possibility to explode values of an array to create direct a new array with these values. I'm able to do this only with a intemidiate step.

I have following array:

Array (
[0] => OtherMachines, Polymers
[1] => Engines/Pumps/Turbines, Measurement
[2] => Materials/Metallurgy
[3] => Materials/Metallurgy, ThermProcesses
)

Then I explode its values:

foreach ($array00 as $v) {
    $array01 = explode(", ", $v);
}

and receive following array:

Array
(
[0] => Array
    (
        [0] => OtherMachines
        [1] => Polymers
    )

[1] => Array
    (
        [0] => Engines/Pumps/Turbines
        [1] => Measurement
    )

[2] => Array
    (
        [0] => Materials/Metallurgy
    )

[3] => Array
    (
        [0] => Materials/Metallurgy
        [1] => ThermProcesses
    )
)

Than I have to flatten the array to get the one I wish:

// Flatten the array.
$array02 = call_user_func_array('array_merge', $array01);

Final result:

Array (
[0] => OtherMachines
[1] => Polymers
[2] => Engines/Pumps/Turbines
[3] => Measurement
[4] => Materials/Metallurgy
[5] => Materials/Metallurgy
[6] => ThermProcesses
)

Is there any way to do this direct?

Many thanks in advance.

Yes, just implode it and then explode.

$result = explode(', ', implode(', ', $array));
