How can I get the meta tags' returns from another file?-CodePudding

I was editing the meta tags in my project and an idea came to my mind. I wonder if I can pull the content of these meta tags from a google sheets file? In this way, I thought it would be easier when I want to update it again later. Is there a way to do this?

CodePudding user response：

To get the meta tags of a webpage, you can use the get_meta_tags function from the PHP HTML parser library Simple HTML DOM. Here is an example of how you can use this function:

include('simple_html_dom.php');

$html = file_get_html('https://www.example.com/');

$meta_tags = get_meta_tags('https://www.example.com/');

print_r($meta_tags);

This will return an array of the meta tags and their values for the webpage at the specified URL.

Alternatively, you can use the get_meta_tags function to parse the HTML of a local file instead of a remote URL:

$html = file_get_html('path/to/local/file.html');

$meta_tags = get_meta_tags('path/to/local/file.html');

print_r($meta_tags);

You can also use the getElementsByTagName method of the DOMDocument class to parse the meta tags of a webpage. Here is an example of how you can use this method:

$doc = new DOMDocument();

$doc->loadHTMLFile('https://www.example.com/');

$meta_tags = $doc->getElementsByTagName('meta');

foreach ($meta_tags as $meta_tag) {
    $name = $meta_tag->getAttribute('name');
    $content = $meta_tag->getAttribute('content');
    printf("%s: %s\n", $name, $content);
}
