    Books > Computers & Technology > Computer Science
    Books > Computers & Technology > Databases
    Books > Computers & Technology > Hardware > Design & Architecture
    Books > Computers & Technology > Programming > Languages & Tools > Lisp
    Books > Computers & Technology > Software
    Books > Education & Reference
    Books > New, Used & Rental Textbooks > Computer Science > Database Storage & Design

    My target is getting
    Computer Science
    Databases
    Design & Architecture
    Lisp
    Software
    Education & Reference
    Database Storage & Design

    Mhhh... let's see...I assume that every line is stored in an array

    
$library = array(
"Books > Computers & Technology > Computer Science",
"Books > Computers & Technology > Databases",
"Books > Computers & Technology > Hardware > Design & Architecture",
"Books > Computers & Technology > Programming > Languages & Tools > Lisp",
"Books > Computers & Technology > Software",
"Books > Education & Reference",
"Books > New, Used & Rental Textbooks > Computer Science > Database Storage & Design"
);
foreach($library as $string)
{
     $split = explode(" > ", $string);

     echo $split[count($split)-1]."<br />";
}
    PHP:

    Stackoverflow helped a lot

    Mhhh...

    
$section = array();
$library = array(
"Books > Computers & Technology > Computer Science",
"Books > Computers & Technology > Databases",
"Books > Computers & Technology > Hardware > Design & Architecture",
"Books > Computers & Technology > Programming > Languages & Tools > Lisp",
"Books > Computers & Technology > Software",
"Books > Education & Reference",
"Books > New, Used & Rental Textbooks > Computer Science > Database Storage & Design"
);
foreach($library as $string)
{
    $split = explode(" > ", $string);
    $section[] = $split[count($split)-1];
}
 
$result = implode(", ", $section);
echo $result;
    PHP:
    Which results in this

    Computer Science, Databases, Design & Architecture, Lisp, Software, Education & Reference, Database Storage & Design

    Simpler
    $str = explode(' ',$your_string);
echo end($str);
    PHP:
    Oh i didnt know it was an array, but this will get the last word in a sentance etc...
    Will leave it may be useful for someone else.

    @ronnie403 -- look at the data closer, they don't want just the last WORD, they want the last SECTION. (though the OP's broken Engrish is most likely to blame for your thinking such) -- Doesn't want just "Science", wants "computer science", doesn't want just "Design", they want "Database Storage & Design"

    GMF's answer is ok, but would benefit from your suggestion of 'end' as well as building the comma delimited list inside the loop instead of with implode.

    $library = array(
	'Books > Computers & Technology > Computer Science',
	'Books > Computers & Technology > Databases',
	'Books > Computers & Technology > Hardware > Design & Architecture',
	'Books > Computers & Technology > Programming > Languages & Tools > Lisp',
	'Books > Computers & Technology > Software',
	'Books > Education & Reference',
	'Books > New, Used & Rental Textbooks > Computer Science > Database Storage & Design'
);
$result='';
foreach ($library as $string) $result .= end(explode(' > ', $string)).', ';
 
echo trim($result,', ');
    Code (markup):
    ... and of course my nitpick of getting rid of the stupid malfing double quotes :p
