Validating data in php form

21-Oct-2015 16:32

write_function must return the exact number of bytes of the string, so you can return a value with mb_strlen. $mime ."\r\n\r\n"; $body .= $cont."\r\n"; } else $body .= "\r\n\r\n".urlencode($val)."\r\n"; return $body; } public static function Get(array $post, $delimiter='-------------0123456789') { if(is_array($post) && ! This is due to the fact that curl is not part of PHP and doesn't know the values of open_basedir or safe_mode, so you could comprimise your webserver operating in safe_mode by redirecting (using header('Location: ...')) to "file://" urls, which curl would have gladly retrieved.

I hope this can help someone Luca 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.-Philippe Many hosters use PHP safe_mode or/and open_basedir, so you can't use CURLOPT_FOLLOWLOCATION. If server HTTP response codes is 30x, function will forward the request as long as the response is not different from 30x (for example, 200 Ok). "--\r\n"; } else $ret = http_build_query($post); } else throw new \Exception('Error input param!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 ( from this page, but for some reason it did not work properly. Also you can use POST.function curl Exec(/* Array */$curl Options='', /* Array */$curl Headers='', /* Array */$post Fields=''){ $new Url = ''; $max Redirection = 10; do { if ($max Redirection 1440 is the the default number of bytes curl will call the write function (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. '); return $ret; } };$delimiter = '-------------'.uniqid();$file = new o File('sample.txt', 'text/plain', 'Content file');$post = Body Post:: Get(array('field'=$file), $delimiter);var_dump($post);$ch = curl_init();curl_setopt($ch, CURLOPT_URL, ' CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $post);curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data; boundary=' . strlen($post)));curl_exec($ch); If you are trying to use CURLOPT_FOLLOWLOCATION and you get this warning: Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is will want to read Log-4which says "Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled." as of PHP 4.4.4/5.1.5.If you're relying on CURLOPT_SSLVERSION's default setting, you'll never make a successful connection to the server.You can solve this by setting CURLOPT_SSLVERSION to either 5 (for CURL_SSLVERSION_TLSv1_1) or 6 (for CURL_SSLVERSION_TLSv1_2) .

in particular this is NECESSARY if you are using PEAR_SOAP libraries to build a webservice client over https and the remote server need to establish a session cookie.

in fact each soap message is sent using a different curl session!!

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: set a path to it in your file, e.g.

on Windows:curl.cainfo=c:\php\Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want!

In today's changed TLS landscape, you might eventually encounter servers which only operate on TLS 1.1 or TLS 1.2, and will actively refuse TLS 1.0 connections.
