Useful tips on PHP streams
Tue Jun 22 14:56:39 UTC 2010
PHP is a rich language with some features not very popular but extremely useful, like the underlying streams architecture.
Almost all the PHP functions that expect a file, can also accept a URL or stream.
How this can be useful?
Let's say you want to construct a SoapClient in PHP against a regular file containing your WSDL:
$soapClient = new SoapClient('MyService.wsdl');
That will work without problems, but what would happens if you want to construct the same WebService against a string with the exactly content of the MyService.wsdl file?
$content = '';
$soapClient = new SoapClient($content);
That will cause an error because the constructor of this class only accept a file or stream as a parameter.
The solution is to wrap the string into a data stream, in this way:
$soapClient = new SoapClient('data://text/plain;base64,' . base64_encode($content));
Another example can be found when using the PHPExcel library. This library creates spreadsheets and there is not (evident) option to save them to an output stream (stdout).
So, if you want to throw the image into the standard ouput instead of a file, you can invoke this method directly:
writer = new PHPExcel_Writer_Excel2007($excel);
$writer->save('php://output');
Hope you like this article and it has helped you to discover the amazing flexibility of the streams API in PHP.
