Converting Characters

[zbee]

I'd like to know if there is a way to convert commas and periods in a variable to a blank space or to just erase them.
Example:
for the variable:

$text = linux, openserver, VPN. ;

i'd like to convert it to:

$text = linux openserver VPN ;

I'd really appreciate it.

Consider [man]str_replace[/man], [man]preg_replace[/man], or even [man]strtr/man.

Most likely str_replace() will do.

thanx but i could use an example, if you don't mind.

$text = "linux, openserver, VPN."
$text = str_replace(',', '', $text);
$text = str_replace('.', '', $text);
echo $text;

$text = "linux, openserver, VPN."
$text = preg_replace('/[\\.\\,]/', '', $text);
echo $text;

thanx a lot, man. I really appreciate it.
