[PHP-NOTES] note 130572 added to control-structures.foreach

As well as numerically-indexed arrays, nested associative arrays can also be unnested in the foreach()

<?php
$records = [
    ['name' => 'Alice', 'address' => '...'],
    ['name' => 'Bob', 'address' => '...'],
    ['name' => 'Chris', 'address' => '...'],
    ...];

foreach($records as ['name' => $name]) {
    echo "$name\n";
}

foreach($records as ['address' => $address, 'name' => $name]) {
    echo "$name @ $address\n";
}
?>

The usual warnings about undefined array keys will occur if any of the element arrays lack the requested key.

One additional detail, the key is still just an ordinary string-valued expression, so...
<?php

$field = 'address';
foreach($records as [$field => $value]) {
    echo "$value\n";
}
?>
If the value of $field changed within the loop, the new field would be accessed in subsequent iterations.
