PHP: send POST request then read XML response?

阅读更多关于 PHP: send POST request then read XML response?

I'm trying to write a PHP script that sends a POST request to a remote server, then parses the XML response. I can do the POST request, but am having difficulty (from other SO questions) working out how to parse the XML response. My current code gives me: Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "1" in /Users/simon/usercreate.php on line 46 - the simplexml_load_file($response) line. I'm working on a local server, not sure if that makes a difference. Code: $curl = curl_init(); curl_setopt($curl, CURLOPT_URL,$url); curl_setopt(

Which is much faster, XMLParser or SimpleXML

阅读更多关于 Which is much faster, XMLParser or SimpleXML

What do you think guys? I currently using SimpleXML for my entire project, which have average of 250KB in memory usage w/ 500micro seconds processing per execution. I just plan to switch to XMLParser, your advice is much appreciated. Edit : The actual microtime is 0.000578 micro seconds. Im just confused in milli and micro, lol. In most cases, XML Parser will be much slower both in terms of development and execution, mainly because you have to write/execute tons of userland PHP code to navigate/read your document. In some cases, you can find some improvement using XMLReader (not sure about XML

alternatives to simpleXML for parsing xml files with PHP

阅读更多关于 alternatives to simpleXML for parsing xml files with PHP

i just want to know if there are any alternatives to simpleXML for parsing XML Data with PHP. For example if simpleXML module is not loaded or even if there is a lib/class out there that has a better performance then SimpleXML. Obviously there's a ton of different way to process XML both as PHP extensions and userspace librairies. The problem is they are all much much more complicated than SimpleXML and nowhere as fast for random access. I'm not sure what's the goal of your question though. None of those libraries/extensions share a common API so if you want a fallback in case SimpleXML isn't

php xpath problems

I am trying to parse a blogspot feed using xpath but it doesnt seem to be working with anything that I try. I am not sure if it is because of the namespaces or what but I was hoping someone could help me. Here is the code: $xml = simplexml_load_file('http://feeds.feedburner.com/blogspot/MKuf'); $next = $xml->xpath("//link[@rel='next']"); print_r($next); This is just returning an empty array and it should not be. I tried it doing just link or just entry and it still is returning empty. The only one I can run on it that works is *. Any help is appreciated. Like already said in the comment to you

They only work if I remove the attribute part. So how can I check to see if an attribute is set as part of an object? sesser What you're looking at is
