[PHP] Function get_meta_tags() Helper

Description Of get_meta_tags

Source Description: PHP.NET

(PHP 4, PHP 5, PHP 7)

get_meta_tags — Extracts all meta tag content attributes from a file and returns an array

Description

array get_meta_tags ( string$filename [, bool $use_include_path = FALSE ] )

Opens filename and parses it line by line for <meta> tags in the file. The parsing stops at </head>.

Parameters

filename

The path to the HTML file, as a string. This can be a local file or an URL.

Example #1 What get_meta_tags()parses

<meta name="author" content="name">
<meta name="keywords" content="php documentation">
<meta name="DESCRIPTION" content="a php manual">
<meta name="geo.position" content="49.33;-86.59">
</head> <!-- parsing stops here -->
(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.

Return Values

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.
