It is important to notice that header must be called before any actual output is sent In PHP 4 and later, you can use output buffering to solve this problem. First, write those headers correctly. The file name in Content-Disposition is the file name only, not the full path to it, and altrough I don't know if its mandatory or not, this name comes wrapped in " not '.

Also, your last ' is missing. Content-Disposition: inline implies the file should be displayed, not downloaded. Use attachment instead. In addition, make the file extension in upper case to make it compatible with some mobile devices. Update : Pretty sure only Blackberries had this problem, but the world moved on from those so this may be no longer a concern.

Content-Length is optional but is also important if you want the user to be able to keep track of the download progress and detect if the download was interrupted. But when using it you have to make sure you won't be send anything along with the file data.

RiggsFolly I improved the encoding function by Alejandro Moreno to work properly with mulltidimensional arrays. As it is here, it returns the body of the response and not the header.

It also doesn't deal with redirection urls with username and passwords in them. Setting this option to 1 or below will make libcurl do only one try for the exact port number. Although this is stated in the documentation I thought it was worth reiterating since it cause me so much trouble. I've created an example that gets the file on url passed to script and outputs it to the browser. Make sure that there're no new lines before and after code or script may not work.

Note that if you put a certificate chain in a PEM file, the certificates need to be ordered so that each certificate is followed by its issuer i. As others have said, not sending a user agent may cause you to not get the results that you expected, e.

The function working transparent, no problem with header and returntransfer options. You can handle the max redirection with the optional second argument the function is set the variable to zero if max redirection exceeded. When following redirects, libcurl hit the maximum amount. As of php 5. If not, it won't work. By setting this value equal to 1 the peer certificate must contain a Common Name field, but it doesn't matter what name it says. Using cURL, 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. You may supply an array, but there may not be any sub-arrays in this array, as this will give Array-to-string-conversion notice. If you want to connect to a server which requires that you identify yourself with a certificate, use following code.

Your certificate and servers certificate are signed by an authority whose certificate is in ca. For example when the page is trying to look for itself.

The parameter can be found at least in version 5. In fact, on my PHP version 5. XXX" ;? XXX netmask 0xffffffff broadcast XXX inet XXX Otherwise you might encounter Length required error.

As the "example 2 Uploading file" says it is deprecated as of PHP 5. To send a post as a different content-type ie.. Some servers will return weird errors like "SSL read: errorlib 0 :func 0 :reason 0 , errno " for the wrong Content-Type, and you may waste many hours of time trying to figure out why!

I spent a couple of days trying to upload a file using a curl post. The problem I ran into was the filename had an ' ' in the middle of it. I'm posting this in the hopes that it will help someone else, and for my own future reference. If anyone can offer insight into why this works or a better way to handle the ' ' symbol in a filename when using curl to upload I would love to hear it. If you are using curl to do a soap request and consistently get the following error back: The server cannot service the request because the media type is unsupported.

You are sending the Content-type of soap 1. Soap 1. A note on the way Curl posts files Not sure why this conflicts, since the documentation doesn't specify as such. The array used to set the POST fields must only contain scalar values.

If there is a need to send non-scalar values using a POST request, consider serializing them before transmission. You can use also use object methods as callback functions. This is usefull if your curl ressource is part of an object handling transfers. The point is : at the opposite of. Just a small detail I too easily overlooked.

Just something subtle to watch out for. Why do you care? There are other cases, of course, where this option is extremely useful If you are getting the following error: SSL: certificate subject name 'example. The data argument is data received. Note that its size is variable.

When writing data, as much data as possible will be returned in all invokes. When writing headers, exactly one complete header line is returned for better parsing. The function must return number of bytes actually taken care of. If that amount differs from the amount passed to this function, an error will occur.

The length argument is maximum length which can be returned. The function must return string containing the data which were read. If length of the data is more than maximum length, it will be truncated to maximum length.

Returning anything else than a string means an EOF. This is because NTLM authorisation is connect-based, not request-based. If the connection is not kept alive and re-used, cURL can never complete the request. You may notice this if you get a status code or max out the number of redirects. As of at least PHP 5. It will cause cURL to timeout. It causes it to stall waiting for data that will never come.

Sorry, I made a mistake. In this case at best it complicate things, at the worst you perform an operation using the wrong cookie session. It can also increase the chance of failure, waste resources, reduce performance and create mess in the file system. The plus of persistent is that In some cases it may be used to accelerate across processes but not many people actually need that and when they do there tend to be better options such as using memcached.

If someone can edit and merge the comments it would be appreciated. With the legacy file upload feature, Curl sends the file name of the actual file and there isn't a documented way to change that behaviour. Note that this has been reported not to work in all versions of PHP and I have done the following tests: 5. I had problems with the Wikimedia software and sending a POST request where the data was more than bytes long.

I traced this to cURL adding: Expect: continue to the headers. I hope this note will save you couple of hours debugging :. Example: curl. Took me an hour or so to find out as I wanted to post a reply tweet to twitter which typically start with screenname. This is under the cURL settings. To resolve you need to compile cURL e. Of course you shouldn't disable certificate validation.

I am only doing it because I'm writing code to detect if a site's SSL is broken works with verify peer, doesn't work without. Others maybe are using self-signed certificates and don't want to work out how to make them a root authority. Never ever use live. That will get rid of the Array to String conversion notice. You may also specify the certificate authority file with an environment variable. The size of the buffer to use for each read. The number of seconds to wait while trying to connect.
