In the wordpress codex of get_categories (http://codex.wordpress.org/Function_Reference/get_categories) it says:
Arguments are pretty much the same as wp_list_categories and can be passed as either array or in query syntax.
means that I can put own sql query as args...
I just want to put something like WHERE name LIKE "A%"
to retrieve only category with name starting with A letter...
but how to embed that query to the args...
thanks...
No - it means that you can use the same parameters as wp_list_categories. You can't pass an sql query to either get_categories or wp_list_categories.

thanks esmi,
so what is the simplest way to get what I need..? :)
There isn't an easy way to grab just the categories that start with "A". In theory:
<?php
$a_cats = array();
$args=array(
'orderby' => 'name',
'order' => 'ASC'
);
$categories=get_categories($args);
foreach($categories as $category) {
$first_letter = strpos ($category->name,'A');
if ($first_letter === false) break;
else $a_cats[] = $category;
}
?>might work but I've not tested it. It's purely "off the top of my head".

Thanks esmi, nice trick btw :D
btw your code is not work, it's return empty array...
i have fixed it
and now it's work fine using this code..
foreach($categories as $category) {
$cat_name = $category->name;
if(strtolower($cat_name[0]) == strtolower($_GET['start'])) {
echo $cat_name.'<br />';
}
}once again, many thanks :)
I could not figure it out before that it can be that simple. hahahha
Sometimes it just helps to have someone else to bounce ideas off. :-)
