PHP: curl_setopt - Manualrmckay at webaware dot com dot au ¶4 years ago. Please everyone, stop setting CURLOPT_SSL_VERIFYPEER to false or 0. If your PHP installation doesn't have an up- to- date CA root certificate bundle, download the one at the curl website and save it on your server: http: //curl.
Database administration expert Baya Dewald explores the possibilities of using the SQL Profiler framework to find common performance problems in your SQL Server.
Then set a path to it in your php. Windows: curl. cainfo=c: \php\cacert. Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want! Ed Cradock ¶7 years ago.
Option Set value to Notes; CURLOPT_BUFFERSIZE: The size of the buffer to use for each read. There is no guarantee this request will be fulfilled, however. Earlier this week I passed the Microsoft "Programming in C#" exam. I've been studying for it over the last few months, and have been compiling the blog post. PHP 5 ChangeLog Version 5.6.31. Core: Fixed bug #73807 (Performance problem with processing post request over 2000000 chars). Fixed bug #74111 (Heap.
PUT requests are very simple, just make sure to specify a content- length header and set post fields as a string. Put($url, $fields). CURLOPT_CUSTOMREQUEST, 'PUT'). CURLOPT_RETURNTRANSFER, true). CURLOPT_HTTPHEADER, array('Content- Length: ' . CURLOPT_POSTFIELDS, $fields).
CURLINFO_HTTP_CODE). Put('http: //example. You can grab the request data on the other side with. SERVER['REQUEST_METHOD'] == 'PUT').
Data). print_r($request. Data). DELETE can be done in exactly the same way. Philippe dot Jausions at 1. Clarification on the callback methods: - CURLOPT_HEADERFUNCTION is for handling header lines received *in the response*,- CURLOPT_WRITEFUNCTION is for handling data received *from the response*,- CURLOPT_READFUNCTION is for handling data passed along *in the request*. The callback "string" can be any callable function, that includes the array(& $obj, 'some. Method. Name') format.- Philippejoey ¶1 year ago.
It is important that anyone working with c. URL and PHP keep in mind that not all of the CURLOPT and CURLINFO constants are documented. I always recommend reading the c. URL documentation directly as it sometimes contains better information. The c. URL API in tends to be fubar as well so do not expect things to be where you would normally logically look for them.
So I will talk about what I found with PHP 5. If you want to manage cookies in memory without using files including reading, writing and clearing custom cookies then continue reading. To start with, the way to enable in memory only cookies associated with a c. URL handle you should use: curl_setopt($curl, CURLOPT_COOKIEFILE, ""); c. URL likes to use magic strings in options as special commands. Rather than having an option to enable the cookie engine in memory it uses a magic string to do that.
Although vaguely the documentation here mentions this however most people like me wouldn't even read that because a COOKIEFILE is the complete opposite of what we want. To get the cookies for a curl handle you can use: curl_getinfo($curl, CURLINFO_COOKIELIST); This will give an array containing a string for each cookie. It is tab delimited and unfortunately you will have to parse it yourself if you want to do anything beyond copying the cookies. To clear the in memory cookies for a c.
URL handle you can use: curl_setopt($curl, CURLOPT_COOKIELIST, "ALL"); This is a magic string. There are others in the c. URL documentation. If a magic string isn't used, this field should take a cookie in the same string format as in getinfo for the cookielist constant. This can be used to delete individual cookies although it's not the most elegant API for doing so. For copying cookies I recommend using curl_share_init.
You can also copy cookies from one handle to another like so: foreach(curl_getinfo($curl_a, CURLINFO_COOKIELIST) as $cookie_line)curl_setopt($curl, CURLOPT_COOKIELIST, $cookie_line); An inelegant way to delete a cookie would be to skip the one you don't want. I only recommend using COOKIELIST with magic strings because the cookie format is not secure or stable. You can inject tabs into at least path and name so it becomes impossible to parse reliably. If you must parse this then to keep it secure I recommend prohibiting more than 6 tabs in the content which probably isn't a big loss to most people.
A the absolute minimum for validation I would suggest: /^([^\t]+\t){5}[^\t]+$/DHere is the format: #define SEP "\t" /* Tab separates the fields */ char *my_cookie ="example. Hostname */SEP "FALSE" /* Include subdomains */SEP "/" /* Path */SEP "FALSE" /* Secure */SEP "0" /* Expiry in epoch time format.
Session */SEP "foo" /* Name */SEP "bar"; /* Value */badman ¶3 years ago. Many hosters use PHP safe_mode or/and open_basedir, so you can't use CURLOPT_FOLLOWLOCATION. If you try, you see message like this: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in [you script name & path] on line XXXFirst, I try to use zsalab function (http: //us.
So, I wrote my own. It can be use instead of curl_exec. If server HTTP response codes is 3.
Ok). Also you can use POST. Exec(/* Array */$curl.

Fields)){curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post. Fields); }if (! empty($new. Url)) curl_setopt($ch, CURLOPT_URL, $new. Url); // redirect needed$curl. Result = curl_exec($ch); $code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($code == 3. Location: (.*?)\n/', $curl.

I hope this can help someone. Lucaanderseta at gmail dot com ¶7 years ago. If you wish to find the size of the file you are streaming and use it as your header this is how.

CURLINFO_CONTENT_LENGTH_DOWNLOAD).""). BUFFERSIZE does not affect this, i actually think you can not change this value), so it means the headers are going to be set only one time. If you want to Curl to follow redirects and you would also like Curl to echo back any cookies that are set in the process, use this. CURLOPT_COOKIEJAR, '- '); ?>. Note that CURLOPT_RETURNTRANSFER when used with CURLOPT_WRITEFUNCTION has effectively three settings: default, true, and false.
Note that CURLOPT_HEADERFUNCTION callbacks are always called. If you are doing a POST, and the content length is 1,0. Continue) Status. See http: //www. w. Protocols/rfc. 26. Expect: 1. 00- continue". * it then sends the request head, waits for a 1.
Not all web servers support this though. Various errors are returned depending on the server. If this happens to you, suppress the "Expect" header with this command: < ? CURLOPT_HTTPHEADER, array('Expect: ')); ?> See http: //www. After much struggling, I managed to get a SOAP request requiring HTTP authentication to work. Here's some source that will hopefully be useful to others. Sample. Request. xml".

CURLOPT_POST, 1). CURLOPT_POSTFIELDS, $xml_data). Error: " . curl_error($ch). Using c. URL, I needed to call a third- party script which was returning binary data as attachment to pass on retrieved data again as attachment. Problem was that the third- party script occassionally returned HTTP errors and I wanted to avoid passing on zero- length attachment in such case.
Combination of using CURLOPT_FAILONERROR and CURLOPT_HEADERFUNCTION callback helped to process the third- party script HTTP errors neatly. Header. Callback($res.
