php使用curl实现模拟提交表单功能的方法

//初始化curl
$ch = curl_init();
$url = 'xxx';
$option = [
 CURLOPT_URL => $url,
 CURLOPT_HEADER => 1,
 CURLOPT_RETURNTRANSFER => 1,
];
curl_setopt_array($ch, $option);
$output = curl_exec($ch);
preg_match_all('/Set-Cookie: (.*);/i', $output, $str); //正则匹配
//如果有token的话就获取token
preg_match('/token = \"(.*)\"/i', $output, $token);
if (empty($str)) {
 return false;
}
$cook = $str[1];
$cookie = implode(';', $cook);

$up_url = 'xxx';
$post_data = [
 'name' => 'test_',
 'tel' => '18819271234',
 'email' => 'qqhahadfdfads@163.com',
 'message' => 'this is my message;',
 '_token' => $token[1],
];
$options = [
 CURLOPT_URL => $up_url,
 CURLOPT_RETURNTRANSFER => 1,
 CURLOPT_HEADER => 1,
 CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36",
 CURLOPT_COOKIESESSION => 1,
 CURLOPT_POST => 1,
 CURLOPT_POSTFIELDS => $post_data,
 CURLOPT_COOKIE => $cookie
];
curl_setopt_array($ch, $options);
$res = curl_exec($ch);
// $info = curl_getinfo($ch);
if ($res === FALSE) {
 p('curl Error: ' . curl_error($ch));
}
curl_close($ch);
p($res);
