[SOLVED] Need Some Help - Arrays, Foreach, Newbie stuff...

!Unreal · #1 (**permalink**) 12-22-08, 01:01 PM

Ive made this little script and Im stuck on a few of the basic bits

Basically what this script does is fetches the <head> and <body> of an array of pages. But its not, to put it simply.

Could someone take a look and tell me what Im doing wrong. I think I need to use foreach () somewhere but Im not too sure.

PHP Code:


			
<?php



$req_url = array('http://www.first.com', 'http://www.second.com', 'http://www.third.com');



function get_head($a,$b,$c){ // Gets a string between 2 strings

        $y = explode($b,$a);

        $x = explode($c,$y[1]);

        return $x[0];

    } 



function get_body($a,$b,$c){ // Gets a string between 2 strings

        $y = explode($b,$a);

        $x = explode($c,$y[1]);

        return $x[0];

    }



//Get head

echo get_head(file_get_contents('$req_url'), '<head>', '</head>');



//Gets body

echo get_body(file_get_contents('$req_url'), '<body>', '</body>');

 



?>

Thanks

$y should = 0 not 1 - EDIT: scrap that I see what you've done now sorry

$req_url should be passed as an array and not as a string

use this instead;

PHP Code:


			
//Get head
echo get_head(file_get_contents($req_url[0]), '<head>', '</head>');

//Gets body
echo get_body(file_get_contents($req_url[1]), '<body>', '</body>');

That solves some problems but it still doesnt show 3 pages. Just the one :|

replace the last 2 lines of code with this;

PHP Code:


			

foreach($req_url as $val){
    if($val != "")echo get_head(file_get_contents($val), '<head>', '</head>');
}

Kind Regards
