get_meta_tags
(PHP 3 >= 3.0.4, PHP 4, PHP 5)
get_meta_tags -- Extracts all meta tag content attributes from a file and returns an arrayOpis
array get_meta_tags ( string filename [, bool use_include_path] )
Opens filename
and parses it line by line for
<meta> tags in the file. The parsing stops at
</head>.
Parametry
filename
The path to the HTML file, as a string. This can be a local file or an URL.
(pay attention to line endings - PHP uses a native function to parse the input, so a Mac file won't work on Unix).use_include_path
Setting
use_include_path
to TRUE will result in PHP trying to open the file along the standard include path as per the include_path directive. This is used for local files, not URLs.
Zwracane wartości
Returns an array with all the parsed meta tags.
The value of the name property becomes the key, the value of the content property becomes the value of the returned array, so you can easily use standard array functions to traverse it or access single values. Special characters in the value of the name property are substituted with '_', the rest is converted to lower case. If two meta tags have the same name, only the last one is returned.
