[請益] php 迴圈宣告變數
各位前輩好 由於之前剛學php 亂寫了宣告以下 程式 - -
$cam1 = $_POST['cam1'];
$cam2 = $_POST['cam2'];
$cam3 = $_POST['cam3'];
$cam4 = $_POST['cam4'];
$cam5 = $_POST['cam5'];
$cam6 = $_POST['cam6'];
$cam7 = $_POST['cam7'];
$cam8 = $_POST['cam8'];
$cam9 = $_POST['cam9'];
$cam10 = $_POST['cam10'];
$cam11 = $_POST['cam11'];
$cam12 = $_POST['cam12'];
後來覺得應該可以用迴圈下去跑，看起來比較少行 - -
改成這樣
for ($i = 1; $i < 13; $i++) {
$cam$i = $_POST['cam'.$i];
}
但是這樣就沒辦法跑了 我想請問一下 是我哪邊寫錯了 困擾了好久~~
