ShortListSyntaxCanBeUsed

info on by default quick-fix PHP ≥ 7.1

Group: Language level migration · PhpStorm name: ShortListSyntaxCanBeUsedInspection

From PHP 7.1 destructuring can use the short [...] form instead of list(...), consistent with short array syntax.

Example

Before

<?php
list($host, $port) = explode(':', $addr);
list ('w' => $w, 'h' => $h) = $size;

foreach ($pairs as list($left, $right)) {
    swap($left, $right);
}
foreach ($grid as $row => list (, $cell)) {
    show($row, $cell);
}

while (list($key, $item) = each($legacy)) {
    use_it($key, $item);
}
[$p, $q] = $coords;

After fix

<?php
[$host, $port] = explode(':', $addr);
['w' => $w, 'h' => $h] = $size;

foreach ($pairs as [$left, $right]) {
    swap($left, $right);
}
foreach ($grid as $row => [, $cell]) {
    show($row, $cell);
}

while ([$key, $item] = each($legacy)) {
    use_it($key, $item);
}
[$p, $q] = $coords;
