Remove ?>

You can save 2 bytes by removing the syntax that ends the PHP script when you don't need it. The program will still work.

<?php echo"Hello!";

Anything that's outside the script is echoed

This probably has to deal with the fact that PHP is a script commonly used on HTML, and anything that is written on the HTML document--not inside the script--is outputted.

^{Used on "Hello, World!".}

Whitespace can be removed in between keywords and variables

You can easily remove the whitespace that's in-between a keyword (return or a function that doesn't need parentheses) and a variable (either starting with $ for the variable's name or " if the variable to deal with is a string):

<?php $x=9+10;echo"Hello!\n";echo$x;

Use <?=

It's basically the same as <?php echo.

Set arrays without array()

In a few occasions, setting an array using array() can be a bit costly. Thankfully, you can assign an array like how to assign a Python list.

<?php $a=["Hello","MarkFuncs","Golfing"];print_r($a);
