【サルが書く】phpでのforをforeachで代用してみよう!

More than 1 year has passed since last update.
for ($i = 0; $i <= 5; $i++) {
    echo $i;
}

いつもの書き方でやるならこうしていた。

単純に何回ループを回すって指定したい!

foreachでもrangeを使うことで実装できるようでやってみました。

foreach (range(0,5) as $i) {
    echo $i;
}

でも、foreachを使うことで処理速度が遅くなることがあるらしい、また、rangeを変数に入れてやると処理が早くなるらしい。

$range = range(0,5);
foreach ($range as $i) {
    echo $i;
}
