You also can't do
php:
<?
empty(someFunctionThatReturnsAString())?>
which bit me earlier today.

just do (functionthatreturns() == "")

see:

php:

<?php
function what($return)
{
    switch( $return )
    {
        case "boolean":
            return true;
            break;
            
        case "string":
            return "string";
            break;
            
        case "integer":
            return 1;
            break;
            
        case "array":
            return array("hello", "goodbye");
            break;
            
        case "nothing":
            return;
            break;
    }
}
if( what("boolean") == "" )
{
    echo("what(bool) = nothing<br />");
}
if( what("string") == "" )
{
    echo("what(string) = nothing<br />");
}
if( what("integer") == "" )
{
    echo("what(int) = nothing<br />");
}
if( what("array") == "" )
{
    echo("what(array) = nothing");
}
if( what("nothing") == "" )
{
    echo("what(nothing) = nothing");
}
?>

returns:

what(nothing) = nothing

Careful there. There is no such type in PHP as 'nothing', that use of return with no value actually returns NULL, and NULL, 0, and false are all equal to "".

Oh yeah I know I was just being lazy.

Don't you mean:

preg_match_all("#<br(?: /)?>#", $string, $m)

edit: can't quote your <

correct

Use the cURL http library:

php:

<?php

$ch = curl_init("http://myimageserver.com/image.jpg");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$imagedata = curl_exec($ch);
curl_close($ch);
?>

if cURL isn't enabled, use file_get_contents:

php:

<?php
$file = file_get_contents( 'http://path/.jpg' );
header( 'Content-Type: image/jpeg' ); 
echo $file;
?>

Edit: Why is that an error call within a header call anyway? I'm not familiar with VPet, but it seems like a weird thing to be doing

It probably returns a Location: header.
