这个Php脚本有什么问题？ [关闭]

Question

I created following PHP script that to get a specific world from a HTML page

<?php 

$html = file_get_contents('https://www.topsecret.com/');

$start = "It is a scrambled version of";
$end   = "- so it will be harder to guess which Inbox Id was used";

$output = getBetween($html,$start,$end);

echo $output;

?>

But after running the script I get following errors

Fatal error: Call to undefined function getBetween() in E:\Programming\Projects\xampp>\htdocs\email.php on line 8

But I can't figure out what is wrong with this line:

line: 8 $output = getBetween($html,$start,$end);

This is the first time I am using this function so I don't know much about it.

Answer 1

looking on the web it looks like you either don't have "getBetween" in your script or it could be typod. I see one version out there that looks like this:

function GetBetween($content,$start,$end){
    $r = explode($start, $content);
    if (isset($r[1])){
        $r = explode($end, $r[1]);
        return $r[0];
    }
    return '';
}

Is this what you are using? (note the capital G on the function name)
