HomeBackend DevelopmentPHP TutorialWarning: curl_setopt() [function.curl-setopt]: CURLO...how to solve the error when using php curl function

If you run CURLOPT_FOLLOWLOCATION in PHP and then get the php prompt error message:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…

Error Mentioning the two key words safe_mode and open_basedir, if you are a virtual host and do not have permission to set APPCHE, you cannot solve the problem by modifying the server configuration. Generally speaking, the server configuration safe_mode is off, and then there are some security requirements for users. Restriction, by setting open_basedir to limit the PHP execution folder of the virtual host user, so when you use CURLOPT_FOLLOWLOCATION (php curl function, deep capture data), the error message mentioned in the article will appear once there is a 301 redirect, etc.

After checking the relevant information, I quickly found the solution, http://www.php.cn/php-weizijiaocheng-362563.html. These methods are all available in the official php help.

The specific method is in curl Whether to use curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) in the statement, customize a function in the php function,

The code is as follows:

function curl_redir_exec($ch,$debug="")
{
static $curl_loops = 0;
static $curl_max_loops = 20;
if ($curl_loops++ >= $curl_max_loops)
{
$curl_loops = 0;
return FALSE;
}
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$debbbb = $data;
list($header, $data) = explode("\n\n", $data, 2);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 301 || $http_code == 302) {
$matches = array();
preg_match('/Location:(.*?)\n/', $header, $matches);
$url = @parse_url(trim(array_pop($matches)));
//print_r($url);
if (!$url)
{
//couldn't process the url to redirect to
$curl_loops = 0;
return $data;
}
$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
/*    if (!$url['scheme'])
$url['scheme'] = $last_url['scheme'];
if (!$url['host'])
$url['host'] = $last_url['host'];
if (!$url['path'])
$url['path'] = $last_url['path'];*/
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
curl_setopt($ch, CURLOPT_URL, $new_url);
//    debug('Redirecting to', $new_url);
return curl_redir_exec($ch);
} else {
$curl_loops=0;
return $debbbb;
}
}

After the function is defined, replace the statement curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) with curl_redir_exec($ch)

After this, I think your PHP file should not prompt an error. Regarding this code, you can find it in the official PHP connection.

The official code of PHP is as follows

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
