<?php
if(isset($_POST['submit']))

function do_post_request($url, $data, $optional_headers = null)
{
$params = array('http' => array(
'method' => 'POST',
'content' => $data
));
if($optional_headers != null)
{
$params['http']['header'] = $optional_headers;
}
$ctx = stream_context_create($params);
$fp = @fopen($url, 'rb', false, $ctx);
if (!$fp)
{
throw new Exception("Problem with $url, $php_errormsg");
}
$response='';
while (!feof($fp))
{
$response = $response.fgets($fp);
}
if ($response === false)
{
throw new Exception("Problem reading data from $url, $php_errormsg");
}
fclose($fp);
return $response;
}
$host = 'http://mydomain.com';
$url = 'http://mydomain.com/formHandler.php';
$username = 'admin';
$password = '123456';
$data = array ('action' => 'login','lgname' => $username, 'lgpassword' => $password, 'format' => 'txt');

echo var_dump($reply);
#header('location:'.$host);
#exit;
} else {

If you're wanting this form to submit as soon as the page is loaded, you can add this to the bottom of the page if you're determined in using PHP to submit the form:
如果您希望在页面加载后立即提交此表单，并且您决定使用 PHP 提交表单，则可以将其添加到页面底部：
<?
echo "<script type=\"text/javascript\">
window.onload=function(){
document.forms['paypalform'].submit();
}
</script>";
?>
But that seems like a long way around it. You could just write the javascript into the page... maybe I'm not sure what you're wanting to do, but I thought I'd throw this out.
但这似乎还有很长的路要走。您可以将 javascript 写入页面...也许我不确定您想要做什么，但我想我会把它扔掉。

Using javascript you can submit the form inside PHP code like this: (trick is in last line )
使用 javascript，您可以像这样在 PHP 代码中提交表单：（技巧在最后一行）
$paypalURL = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
$paypalID = '[email protected]';
$form = "<form id='paypal' action='". $paypalURL."' method='post'>";
$form .='<input type="hidden" name="business" value="'. $paypalID.'">';
$form .='<input type="hidden" name="cmd" value="_xclick">';
$itemDetail = "Detail goes here";
$orderId = 4444;
$totalAmountWithFee = 55;
$form .='<input type="hidden" name="item_name" value=" '.$itemDetail.'">
<input type="hidden" name="item_number" value="'.$orderId.'">
<input type="hidden" name="amount" value="'.$totalAmountWithFee.'">
<input type="hidden" name="currency_code" value="USD">';
$form .="<input type='hidden' name='cancel_return' value='http://localhost/public/cancel.php'> <input type='hidden' name='return' value='http://localhost/success.php'>";
$form.="<script type=\"text/javascript\"> document.forms['paypal'].submit();</script>";
echo $form;

You can submit an HTML form from a PHP script with cURL or this library (that is based on cURL and simple html dom).

require_once 'fsubmit.php';
$html = '<form action="backend.aspx" method="post"><input type="text" name="question"></form>';
$form = new Fsubmit();
$form->url = 'http://the_url_must_contain_action_url_base'; // If form action is a relative link, then url is a required parameter, if form action is an absolute link, then this parameter can be omitted
