preg_replace question

[leegold2]

preg_replace(", "," ",$kw_str2) ;

This does not replace commas with spaces. What am I doing wrong?
Thanks,

Missing delimiters, you should have received a warning (if not check
error_reporting in your php.ini, it should be set to E_ALL).

Possible solution: preg_replace('# ,#', ' ', $kw_str2); // # = delimiter

But str_replace() would be more efficient in this case.

What? Could you explain, I thought I put a regex pattern in there -
what's this delimiter requirement?

I have never had any luck w/this function - it does not imo work like PERL.

PERL.

In Perl:
$kw_str2 =~ r#PATTERN#REPLA CEMENT#;

In PHP:
$kw_str2 = preg_replace('# PATTERN#', 'REPLACEMENT', $kw_str2);

Where in both PATTERN is an expression and REPLACEMENT is a string

"Perl-Compatible", not Perl.
The reason it is called "Perl-compatible regexp" resides in the PATTERN
part, wich use the same expression as in Perl.
