Get An Array Of Meta Tags Php

Question

How can I get all of the values from the named 'tag' and echo them on the page? this is the HTML im using:

Solution 1:

get_meta_tags returns an array, use print_r() to see it's structure, and loop through them to print them however you want:

foreach($tagsas$tag){
  echo$tag."\n";
}

Edit: And you don't need to stick the restult of get_meta_tags in another array, then you just have an extra one for no reason.

explode(',',$meta['tags']);

Solution 2:

If your question is now how would I get comma-separated values as different tags?, you could do something like this:

<meta name="tag" content="plant, leaf, waterdroplet, water" />

$tags = get_meta_tags('yourfile.html');
$tags = array_map('trim', explode(',', $tags['tag']));

This will explode the words into an array, and remove any whitespace, you can then loop over this for outputting/whatever else:

example

foreach($tagsas$k => $v) {
  echo$k . ': ' . $v . '<br />' . "\n";
}

Would output:

0: plant1: leaf2: waterdroplet3: water

Solution 3:

You are getting the tags correctly, but not displaying them correctly.

You can't use echo on an array.

You can use var_dump to see the whole array that you have - which should show you how to access it in your code.

Solution 4:

You are making a mistake in setting the tags

<metaname="tag"content="xx" /><metaname="tag"content="yz" />

When you execute get_meta_tags() on that, it will only show you the last value (in that case: yz)

So you need to put different names on the tags

eg

<metaname="tag1"content="yz" /><metaname="tag2"content="yz" />

Solution 5:

The names must be unique. See the documentation of this function:

 If two meta tags have the same name, only the lastoneis returned.

So you can only have on meta-tag with name="tag", so better try a comma separated value for that.
