syntax question

  • I’ve been delving into WordPress theming and I keep coming across an expression or two that I don’t understand, it’s this => It sort of seems to act like what it looks like, an arrow. I’m familiar with the standard less than/equal to <=, the greater than/equal to >=, but I have no idea what this expression means, or what function it performs. I’ve also seen a version with the minus sign ->.

    I know some basic php scripting, but I only ever see this thing in WordPress themes. What is it?

    Is this a PHP question?

    Not a PHP guru, but I googled your question and found this:

    Masi => is the separator for associative arrays. In the context of that foreach loop, it assigns the key of the array to $user and the value to $pass.

Example:

$user_list = array(
    'dave' => 'apassword',
    'steve' => 'secr3t'
);

foreach ($user_list as $user => $pass) {
    echo "{$user}'s pass is: {$pass}\n";
}
// Prints:
// "dave's pass is: apassword"
// "steve's pass is: secr3t"

Note that this can be used for numerically indexed arrays too.

Example:

$foo = array('car', 'truck', 'van', 'bike', 'rickshaw');
foreach ($foo as $i => $type) {
    echo "{$i}: {$type}\n";
}
// prints:
// 0: car
// 1: truck
// 2: van
// 3: bike
// 4: rickshaw

    It’s used to associate properties and values in an array; https://www.w3schools.com/php/func_array.asp

    I’ve also seen a version with the minus sign ->.

    That’s used to get properties of an object.
