Functions should be called with no spaces between the function name, the opening parenthesis, and the first parameter; spaces between commas and each parameter, and no space between the last parameter, the closing parenthesis, and the semicolon.

Here's an example:

<?php
$var = foo( $bar, $baz, $quux );
?>

As displayed above, there should be one space on either side of an equals sign used to assign the return value of a function to a variable. In the case of a block of related assignments, more space may be inserted to promote readability:

<?php
$short         = foo( $bar );
$long_variable = foo( $baz );
?>
