Does PSR-2 require vertical alignment?

What is allowed between these two:

$value = 'value';
$user = 'John';
$timestamp = 1480927909;
$day = date('Y-m-d', $timestamp);

or

$value     = 'value';
$user      = 'John';
$timestamp = 1480927909;
$day       = date('Y-m-d', $timestamp);
Solution

  • PSR-2 does not have specific rules for this kind of inter-line alignment:

    From the PSR-2 Conclusion:

    There are many elements of style and practice intentionally omitted by this guide. These include but are not limited to:

    • Declaration of global variables and global constants
    • Declaration of functions
    • Operators and assignment
    • Inter-line alignment
    • Comments and documentation blocks
    • Class name prefixes and suffixes
    • Best practices

    Future recommendations MAY revise and extend this guide to address those or other elements of style and practice.

    For what it's worth, inter-line alignment was discussed for PSR-1 by the PHP-FIG Group, but was removed from the final version:

    The way-back original long-form PSR-1 covered inter-line alignment, globals, ternaries, assignment, and lots of other things. Those ended up getting removed for various reasons; their epitaph is at the conclusion of PSR-2.
