I cannot use implode with the ImageTTFText function. 

The following code does not work, it returns a broken image:

<?php
    Header("Content-type: image/png");
    //$string = "Test";
    $string = implode(" ", "$argv");
    $string = urldecode($string);
    $im = imageCreateFromPng("header_img2.png");
    $white = ImageColorAllocate($im, 167, 194, 206);
    $px = (imagesx($im)-7.5*strlen($string))/2;
    ImageTTFText($im, 30, 0, $px, 42, $white, "/usr/local/apache/htdocs/ttf/ARTBRUSH.TTF", "$string");
    ImagePng($im);
    ImageDestroy($im);
?>

If I comment out the implode line and set $string then it works great. I use implode with other code for creating other images but not with ImageTTFText.

Thanks!

Ok, the status is changed to Bogus. Is this working as designed and not a problem/bug? Thanks,

$argv is an array, and implode() takes an array.  Sterling is wondering to the powers that be why in God's name you passed $argv in quotes (thereby making it a string) to the implode function.

Oh, I don't know why I did that.... I took the "" off and it is still not working... errrr... Any ideas? Sorry to take up your guys time on this...

So stop and debug it without the image-related stuff in there.

OK, I am an idot...

Setting register_globals to on fixed my problem. When it is set to off I get "Bad arguments to implode()" I am not sure why some of my scripts still work and others don't... 

Sorry to have logged this bug, of couse it is not a bug... errr

Thanks!!
