Define array index after function call

问题:

In other languages such as C# and JavaScript, I am able to access the index of an array with a function call such as

getMyArray()[0] 

This would allow me to access the first index of the result instead of passing back the entire array and then setting the result.

However this shortcut does not work with PHP. Is there a way to get this shortcut?

回答1:

You need to be running PHP 5.4 in order to use array de-referencing.

回答2:

// PHP 5.4
$item = getMyArray()[0];

// Older than 5.4: (not recommended)
list($a)   = getMyArray();  // getMyArray()[0]
list(, $b) = getMyArray();  // getMyArray()[1]
