Very simple strpos() problem

rickead2000

Hi,

I'm sure this is very very simple!

How can i differentiate between strpos() returning nothing (as in search string not found) and it returning 0 (as in search string found at position 0)

I am using a while look to break down a larger string and eventually terminate when there are no more "|"s ...

while (strpos($data,"|")!=FALSE)
{
code
}

But this is determining strpos to be returning false when it found "|" as the first character.

Any ideas?

Thanks!

Try it like this

while (strpos($data,"|")!==FALSE)
{
code 
}

OR LIKE THIS:

$_tmp = explode("|",$data);

You might want to read the manual for [man]strpos/man, it explains quite clearly how to differentiate between 0 and false.

Hi,

Thanks for your replies.

I have now modified my code such that it now reads...

while (strpos($data,"|")!===FALSE)
{
code 
}

(included 3 '=' as per the documentation.

However, now PHP is saying there are too many '='

Parse error: parse error, unexpected '=' in /var/www/html/file.php on line 453

There is no such operator (!===) in php ...
And I think [man]explode[/man] is going to be more helpful ...

thanks bogu!

explode does exactly what I was trying to achieve
