Indenting and spacing

• 2 spaces. No tabs!

Blocks

• { and } are on separate lines, unless the content is only one statement.
• For/while/if/foreach are always surrounded by {}, even if they are only executing one statement.

Formatting

• One space between for/if/foreach/while and the following opening bracket.
• Empty line between the "global" line and the rest of the code in a function.
• Empty line between the final "return" statement and the rest of the code in a function.
• Parameters to "echo" always between brackets, even if PHP does not require it.
• No trailing spaces on any line!

Optimization

• Use internal caching functions as much as possible.

PHP tags

• No short tags, always use the full <?php instead of <? and <?php echo($foo); ?> instead of <?= $foo ?>.

Shebang

• For command-line executable scripts, use /usr/bin/env instead of a direct path to the php interpreter binary.
