Arrays

Numerically Index Arrays

Each array element should be separated by a comma and a space character. If wrapping an array across multiple lines, subsequent lines should be indented.

$shapes = array("circle", "square", "triangle", "hexagon");
$colors = array(
    "red", "pink",
    "green", "purple"
);

Associative Arrays

Associative arrays should have a space before and after the => assignment. Array indexes should be quoted using single quotes ('). Short arrays can contain all elements on a single line, but it's recommend to set each index on its own line.

$blocks = array(
    'circle' => "red",
    'square' => "pink",
    'triangle' => "green",
    'hexagon' => "purple"
);

Multidimensional Arrays

Each array depth should be indented one level. The ending parenthesis of the array should be indented such that it aligns with the indent level of its defining index.

$polygons = array(
    'triangles' => array(
        "obtuse",
        "acute",
        "right"
    ),
    'quadrilaterals' => array(
        "square",
        "rhombus",
        "rectangle"
    )
);

Constants

Constants should always be capitalized.
