Parameters

File Name
As a string. This can be a local file or URL.


For example, #1 get_meta_tags () Parsing





"/Header" "! -Resolution stops here-"(note the end of the line-the usage function of PHP parses local investment, so the Mac file will not work in Unix ).

Use_include_path
Setting use_include_path to TRUE causes PHP to attempt to open the file by following the include_path command along the road. This is used for local files, not URLs.


Return Value
Returns all resolved meta tags of an array.

The Value Name attribute becomes the value of the property of the key value content, which is returned to the array, so that you can easily use standard array functions to traverse or access a single value.
