我有這個表格：<form method='post'> <input name='i' type='hidden' value='' > <input name='email' type='text' > <input name='pass' type='password' > <input type="submit" ></form>以及打印 .txt 文件中的數據的 PHP 代碼：<?php $handle = fopen("data.txt", "a"); foreach($_POST as $variable => $value) { fwrite($handle, $variable); fwrite($handle, "="); fwrite($handle, $value); fwrite($handle, "\r\n"); } fwrite($handle, "\r\n"); fclose($handle); exit;?>結果是：i = 價值電子郵件 = 價值通行證 = 價值我不需要打印$_POST['i']值。任何想法？

添加一個 IF 來測試$variable循環i迭代，然后使用continue;
您還可以使用一個寫入每一行的所有數據fwrite
<?php
$handle = fopen("data.txt", "a");
foreach($_POST as $variable => $value) {
if ( $variable == 'i' ){
continue; // will stop this itereation and continue with the next
}
// make one write for all 4 bits of data.
fwrite($handle, "$variable = $value \r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
