我制作了一个 PHP 脚本，它遍历来自 ajax 请求的 POST 数据并将电子邮件发送给适当的收件人。在大多数情况下，脚本可以工作，但是我有两个函数可以验证和清理 POST 数据。
问题是这两个函数没有被调用，实际上在电子邮件实际发送时被评估为字符串。我已经尝试了几种不同的方法来使其相应地发挥作用，包括通过引用传递变量，但无济于事。这里有人能发现问题吗？
<?php
error_reporting(E_ALL);
function validate($value){
$value = strip_tags($value);
$value = htmlspecialchars($value);
$value = stripcslashes($value);
return $value;
}
function detectUrl($string){
$pattern = "/https?\:\/\/[^\" ]+/i";
$val = preg_match_all($pattern, $string);
if($val > 0){
$replace = preg_replace($pattern, '', $string);
return $replace;
} else {
return $string;
}
}
if(isset($_POST) === true){
# Include our DB connection
if (!empty($include_func)) {
require_once $_module_dir . XC_DS . 'func.php';
}

$date = date("d/m/y");
// Get Form content
$content = $_POST;
// Begin message body
