Question

any idea how if the following is possible in PHP as a single line ?:

<?php $firstElement = functionThatReturnsAnArray()[0]; 

… It doesn’t seem to ‘take’. I need to do this as a 2-stepper:

<?php $allElements = functionThatReturnsAnArray(); $firstElement = $allElements[0]; 

… just curious – other languages I play with allow things like this, and I’m lazy enoug to miss this in PHP … any insight appreciated …

Answer 1

Try:

<?php $firstElement = reset(functionThatReturnsAnArray()); 

If you’re just looking for the first element of the array.
