Trimming off characters

[mrgrammar]

Is it possible to trim a string down to a particular character? For example, I want to have both categories and subcategories in my directory. I have a table called categories. I have to relate the subcategories with the categories. Categories and subcategories are named as follows:

Cat1
Cat1::Subcat1
Cat1::Subcat2
Cat1::Subcat3
Cat2
Cat2::Subcat1
Cat3
Cat3::Subcat1
Cat3::Subcat2

The two colons are used only for this example. They can be replaced with any delimiter.

When subcategories appear in the web pages, of course, I don't want the category name to appear as part of it. Therefore, I need to remove all characters up to the 2nd colon.

Is it possible to trim off all characters up to a delimiter and what is the proper delimiter to use?

with explode you can use any delim you want, and it splits the text into an array

$text = "category1::subcategory1";
$parts = array();
$parts = explode("::", $text);
echo "Main category is " . $parts[0] . "<BR>";
echo "Sub category is " . $parts[1] . "<BR>";
