Hello PHP-FIG members,
I would like to start a discussion regarding a potential refinement or an
allowed alternative in the PER Coding Style (successor to PSR-12),
specifically concerning section *5.1 (if, elseif, else)*.
Currently, the standard strictly requires else and elseif to be on the same
line as the closing brace of the previous block:
PHP
if ($expr1) {
// body
} else {
// body
}
*The Problem: Code Folding & Scannability* In modern development
environments (JetBrains PhpStorm, VS Code, Sublime Text), the "Code
Folding" feature is essential for navigating large files. When a developer
collapses an if block following the PSR-12 standard, the else keyword often
gets hidden or visually merged into a single line like: if ($expr1) { ... }
else {
This makes it difficult to quickly scan the code to see if an alternative
logic branch exists without unfolding every block.
*The Proposal:* I propose to allow (or recommend as an alternative) placing
else and elseif on a new line, similar to the Allman style but keeping the
opening brace on the same line as the keyword:
PHP
if ($expr1) {
// if body
}
elseif ($expr2) {
// elseif body
}
else {
// else body
}
*Benefits:*
1.
*Improved Visual Hierarchy:* Each logical branch starts on its own line,
making the structure clear at a glance.
2.
*Better IDE Integration:* When the if block is folded, the else or
elseif remains clearly visible on the next line, preserving the "map" of
the logic.
3.
*Consistency:* It aligns with how many developers naturally separate
distinct logical steps.
I understand that PSR-12 aimed for vertical compactness, but with
high-resolution monitors and the heavy use of IDE folding features, the
"saved line" often comes at the cost of readability.
I would love to hear the community's thoughts on whether the PER Coding
Style could be updated to allow this formatting as a valid alternative.
Best regards, Amanzhol Zhaparov
