Dynamically adding meta tags using php

问题

In my site I have a list of categories and I have to put meta keywords and description for them.I have a single page where I will retrieve the categories from the database.

Can anyone tell me how to make this much simpler to put meta tags for all the categories.

I'm not sure if this is what you are looking for but...

I have a simple script I created to dynamically populate the meta keywords with random keywords taken from an array.

Put this in the header of your template file.

<meta name="keywords" content="<?php get_keywords()?>" />

This will create a comma delimited list of no more than 10 keywords from an array of keywords. If you wanted to avoid a database query each time you could hard-code arrays of possible keywords for each category. If you don't mind a query, you could replace the array with a query which returns an array.

function get_keywords(){
    $keywords=array('keyword1','keyword2','keyword3','keyword4','keyword5');
    if (count($keywords)<10)
        $max=count($keywords);
    else
        $max=10;
    $rand_keys = array_rand($keywords, $max);
    foreach($rand_keys as $vals){
        $keyword[]=$keywords[$vals];
    }
    echo implode(", ", $keyword);
}

Hope this helps.
