I have a github repo for phpcrawl that I'm using successfully in PHP8. It's installable by composer, or you can just download and install the package where you want. https://github.com/JamesShaver/phpcrawl
Maybe, but that's only your first error. Be prepared for other php8 differences that won't work.
So is it as simple as finding each() and changing each to another function? if so what would the new function be?
There's your problem.

Hi, due to your hint I was able to get this command working: $crawler->addURLFilterRule("/\/Category\/.+\/Search/"); Thanks for your help!
Thanks for your reply! I'll give it a try and let you know!
By the way, I didn't actually try it because I don't have those set up, but this is my example: https://www.regexpal.com/?fam=107703
You're close. The dot matches any (single) character except line breaks, but you need to match ALL of the characters. Try this: (\/Category\/.+\/Search)
I'm having an issue in creating the correct regex for this situation: The Crawler should ignore url's like: http://mysite.com/Category/ProductA/Search http://mysite.com/Category/ProductB/Search http://mysite.com/Category/ProductB/Search But it should crawl this url: http://mysite.com/Search I tried this: $crawler->addURLFilterRule("/Category\/.\/Search/"); and $crawler->addURLFilterRule("#/Category\/.\/Search/#"); But still the first 2 url's are also crawled. What would be the correct regex to prevent...
PHPCrawl doesn't natively use a MySQL database. It's up to you to define the schema and implement for your needs.
I'm a new user. I want to try PHPCrawl. I need to create the database and the tables needed for the program's function. I searched for all directories and files and nowhere I found the necessary function or at least the mysql query to create blank tables (search apod.) Can you please advise me where I could find the necessary information? Thank you.
Okey thanks. Lets work with the given data, but Google has crawler that can handle that! Otherwise thate would be cloaking and not allowed by Google.
If the page is loaded via javascript, you will NOT be able to do anything with it in PHP, other than fetch the url it's loaded from. Curl is not a browser and only fetches/pushes things for you. it's up to YOU to interpret the data that comes back, and that includes anything dynamic like JS.
Some pages do load content dynamicly via ajax for performance reasons. So when i open a Page like this https://www.zalando.at/damenbekleidung-hosen-shorts/ it shows a huge amount of products. But the crawler sees only 6 products! When you show the source code there are also only 6 products, the other one are loaded dynamic via js.
You ever find a solution ?
Go to pakagist, upload it there and install via composer
Thanks. It works.
IN PHPCrawlerHTTPRequest.class.php after if ($this->proxy != null) { I changed: $context_proxy = stream_context_create(array('ssl' => array( 'verify_peer_name'=>false, 'SNI_enabled' => false))); $this->socket = stream_socket_client('tcp://'.$this->proxy["proxy_host"].":".$this->proxy["proxy_port"], $error_code, $error_str, $this->socketConnectTimeout, STREAM_CLIENT_CONNECT, $context_proxy); Worked for me
thanks!
SSL requests return 'HTTP/1.1 400 Bad request' in PHP 7
The 301 redirect is server side, so then there won't be any content to receive.
yes , actually requested page is having status of 301, and returning to subdomain url with https url. and i want to get the html of page
What have you tried? Getting the html from the 301 page would be nearly identical of a 200 page.
Hi, I need the html of page , where the http status has return 301 , for example http://www.test.com 301 https://www.test.com (i want html of this page) how to achive that , please need help regarding the same

Yes cut use cli if you can
Is PHPCrawl run in unix-based(Linax) shared hosting ?
Do the multiprocess docs apply to you? Some PHP-extensions are required to successfully run phpcrawl in multi-process mode (PCNTL-extension, SEMAPHORE-extension, PDO-extension). For more details see the requirements page. The multi-process mode only works on unix/linux-based systems Scripts using phpcrawl with mutliple processes have to be run from the commandline (php CLI) Increasing the number of processes to very high values does't automatically mean that the crawling-process will go off faster!...
Yes. but it takes a long time.
Have you tried it without multiprocess?
This is my code. It not works. When i run this, it returns nothing. No results or no errors. I don't know where is my fault.

change /libs/UrlCache/PHPCrawlerSQLiteURLCache.class.php line 273 to //if ($this->PreparedInsertStatement == null) { and line 285 to //} then it works
Use the cli version with multiprocessing.
I tried to grab all links from https://tangailpratidin.com/ . but it takes a lot of time. Anyone can help to improve runtime of crawling or any idea can give. thanks

Same Problem with PHP 7
This is a good feature that I'm also looking for.
All I'm trying to say is that you need to first scrape the token value and then post the token in your post_data array. There's a bunch of ways to do that...
Thanks. I have found this which seems more related to my question: https://stackoverflow.com/questions/36198970/does-using-csrf-form-tokens-help-spam-prevention Curiously, the website I am targetting has no CAPTCHA on the form.
Maybe a good read.... https://stackoverflow.com/questions/6412813/do-login-forms-need-tokens-against-csrf-attacks
However I know that other bots are connecting and interacting with the website.
That's actually the point of csrf, to prevent you from doing this. Good luck...
Well, I do not know how to do it as the CSRF seems to be embedded on the cookie itself. I simply do not understand how this all fits together... General Request URL:https://www.interpals.net/app/auth/login Request Method:POST Status Code:302 Remote Address:104.20.197.2:443 Referrer Policy:no-referrer-when-downgrade Response Headers cache-control:no-cache cache-control:no-store, no-cache, must-revalidate cf-ray:3a974ce47ead2f4d-MAD content-type:text/html; charset=UTF-8 date:Fri, 06 Oct 2017 08:37:44...
Yes, it does matter. You need to post the csrf_token too.
I want to use PHP Crawler to trigger artificial hits on user profiles in https://www.interpals.net but I have been unsuccessful so far.

thank you boss
...bug has to do with Apache sometimes setting Transfer-Encoding: chunked see: http://www.trigon-film.org/en/movies/Centaur/photos/large/Centaur_02.jpg I was able to get around the problem by forcing the crawler to HTTP 1.0 by setting $crawler->setHTTPProtocolVersion(PHPCrawlerHTTPProtocols::HTTP_1_0);

Is there a way to configure the crawler to return only what is between the <body> tags as the document info. (I don't need anything in the head and the css etc..)
The crawler don't use curl, the function setProxy recall this function: stream_socket_client($this->proxy["proxy_host"].":".$this->proxy["proxy_port"], $error_code, $error_str,$this->socketConnectTimeout, STREAM_CLIENT_CONNECT); i try to exec this with socks5 but the error is: “unable to connect to socks5://127.0.0.1:1080 (Unable to find the socket transport "socks5" - did you forget to enable it when you configured PHP?)”
What have you tried?
Search for only PDF do not work.
yes in this way i can hit the proxy but how can i pass it to the crawler?
Have you tried hitting the proxy outside of phpcrawl? $url = "https://google.com"; $proxy = "127.0.0.1:1080"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_PROXY, $proxy); curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); curl_setopt($ch, CURLOPT_HEADER, 1); curl_exec($ch); curl_close($ch);
This don't run for me, i have curl 7.47 but if i try this into my code raise me this error : Unable to connect to proxy 'socks5://127.0.0.1' on port '1080'.

Hi, Sure you can. Use phpcrawl to generate the URLs, then write a script of your own to parse the pages for the data you want. I would suggest using the HTML DOM: $html = str_get_html($file_contents); $elem = $html->find('div[id=content]', 0);
Hello, I would like to crawl a website and retrieve two values (for example the contents of div 1 and div 2) for each url and export these 3 fields into a csv, each line corresponding to a url and these two values. How can this be achieved ? Thank you in advance for your help.
Sometimes I should read the manual before asking. It's $DocInfo->host what I was looking for. http://phpcrawl.cuab.de/classreferences/PHPCrawlerDocumentInfo/overview.html
Within the handeDocumentInfo how can I get the URL to crawl value again? I'm saving all entries to my DB but can't figure out how I can get this value again within this loop ... thx
Remember grade school math? It would help us see the issue if you show your work.
Same Problem as Vinay. Has anyone a solution?
