$arr = array();
$arr["name"] = "marjel101";
$arr["course"] = "PHP";
$arr["platform"] = "SoloLearn";

Use this function to sort arrays:

print_r($arr);
sort($arr);
print_r($arr);

"; sort($arr); print_r($arr) . "\n"; ?>

As you see the downside is that you loose the keys of the key-value pairs in the array. So use "sort" only for linear arrays.

Instead, if you have an array with key-value pairs, use "ksort" to sort on keys:

ksort($arr);

And use "asort" when you want to sort on values:

asort($arr);

This one is fun: it makes an array out of a string:

$string = "I want to learn PHP";
$temp = explode(" ", $string);
print_r($temp);

Please leave a comment if you see an error or if you like to add something I can learn from.
