[PHP] Empty delimiter error - ??

[Rich Pinder]

I'm totally unfamiliar with php, and making some slight modificiations
to Chris Heilmann's nice v 1.1 Newsleterscript.

What exactly is meant by an empty delimiter?  This code works just fine,
but I get the following error:

Warning: Empty delimiter in /home/sites/site56/web/trailcrew.php on line
63



# Put the entries into the array lines
$lines = explode("%",$content);
for ($key=1;$key

[PHP] Empty Delimiter error

Let me try again:

This line of the script:

if (!stristr($lines[$key], $email)) {


yields the following error:
Warning: Empty delimiter in /home/sites/site56/web.


Do you know what causes this error ?

Thanks

Thanks so much Daniel.

Indeed,  the old line that I modified didnt use a function call.

The old line was:
if ($lines[$key] != $email){

So, the  @  suggestion works just fine:

if (!@stristr($lines[$key], $email)) {  

Seems like a cryptic syntax for an error code of this meaning - and odd
that all the PHP sources I searched before posting here came up empty
for the terminology.

Thanks again
Rich
