Get the category in wordpress

I like wordpress very much, so I worked with it for many times.
Sometimes I cannot find my wordpress code which I stored them in my computer.
So I created the blog and saved my wordpress research and code here.

In the first post, I will post basic code when you work with category .

1- get_the_category:

You want to get the current category name, you can use it:

<?php
$category = get_the_category();
echo $category[0]->cat_name;
?>

You want to get the current category id, the same is below:

<?php
$category = get_the_category();
echo $category[0]->cat_ID;
?>

2- Get category by slug
Example we have slug with a variable: $pageslug

$pageslug= ‘news’;
$catslug = get_category_by_slug($pageslug); // get category of the same slug
$catid = $catslug->term_id; // get id of this category

3- Get the slug of current category with query var

<?php if(is_category())
{
$cat= get_query_var(‘cat’);
$yourcat= get_category ($cat);
echo ‘the slug is ‘.$yourcat—>slug;

}
?>
