我在里面放了一些变量，现在试着回显它们。
echo $from;
echo $message;
echo $sent_timestamp;
PHP页面一直加载，然后大约10秒后变成空白。
我只是在尝试我的手在PHP，所以我不是那么先进。欢迎提出任何意见或建议。
$error = NULL;
if (isset($_POST['from'])) {
$from = $_POST['from'];
} else {
$error = 'The from variable was not set';
}
/** * Get the SMS aka the message sent. */
if (isset($_POST['message'])) {
$message = $_POST['message'];
} else {
$error = 'The message variable was not set';
}
/** * Get the timestamp of the SMS */
if (isset($_POST['sent_timestamp'])) {
$sent_timestamp = $_POST['sent_timestamp'];
}
在条件中定义变量。只有在满足正确的条件时才会定义变量。
$from = (isset($_POST['from'])) ? $_POST['from'] : "From var not set";
$message = (isset($_POST['message'])) ? $_POST['message'] : 'The message variable was not set';
$sent_timestamp = (isset($_POST['sent_timestamp'])) ? $_POST['sent_timestamp'] : "The time var was not set";
使用此方法可确保无论如何都可以设置变量
