How to push array with key?

Question

I want do like this:

$m_array = array();

foreach ($values as $key) { <- $key is just string
    array_push ( $m_array, $key => array() );
}

/////result
$m_array = array(
    "key1" => array(),
    "key2" => array(),
    ....
);

How to do this?

You don't need to use array_push to append to arrays. array_push is the same as $array[] = $val.

In your case you want to specify keys:

$m_array = array();

foreach ($values as $key) { <- $key is just string
    $m_array[$key] = array();
}

Note that array_push does have a use if you want to push more than one value at once because you can do something like this:

array_push($array, $value1, $value2, $value3)

$key here is not the array key; which may or may not be an issue

Yes, $key here refers to a value of $values which will be a key in the new array - Not confusing at all! /s
