Access array element from function call in php

instead of doing this:

$s=explode('.','hello.world.!');
echo $s[0]; //hello

I want to do something like this:

echo explode('.','hello.world.!')[0];

But doesn't work in PHP, how to do it? Is it possible? Thank you.

Answer 1

As the oneliners say, you'll have to wait for array dereferencing to be supported. A common workaround nowadays is to define a helper function for that d($array,0).

In your case you probably shouldn't be using the stupid explode in the first place. There are more appropriate string functions in PHP. If you just want the first part:

echo strtok("hello.world.!", ".");

Answer 2

Currently not but you could write a function for this purpose:

function arrayGetValue($array, $key = 0) {
    return $array[$key];
}

echo arrayGetValue(explode('.','hello.world.!'), 0);
