I am getting the output as XML, but i need to store it in a separate xml file, can any one help me out.
One more question,....
I am using fwrite and able to write into a file, but how can i clear the file each time it writes, instead of writing at the end of file? i need the existing content to be destroyed and re written again.
Use fwrite .
EDIT: To truncate, use:
$handle = fopen($filename , "wb")
when doing the open. The w means open for writing and truncate to 0 length. The b means binary mode so Windows doesn't mess with your line endings.
file_put_contents是将字符串转储到文件的最简单方法。
只需简单的文件功能,即可在PHP.net网站上进行检查。
In addition, you wanna make sure your properly escape the contents of the XML file. htmlentities() is a good place to start reading up on the subject, or you can just use <![CDATA[ ... ]]>
