Whitespace not allowed

[damasta]

I'm trying to figure an if statement. A person's username cannot contain any whitespace. I don't think

$username != " "

will work. I'm not at my desk right now so I haven't been able to try it. Any ideas? Thanks.

strpos would be the fastest solution
it returns boolean false if the given string isn't found

if (strpos($username,' ')!==false)

check http://php.net/manual/en/function.strpos.php for details

well if u want to check if the string is blank then it wud work ...but if u want to check if the string contains white spaces...

if (preg_match("/[ \t]/",$u_name))
	print " Whitespaces found";
else
	print "No whitespaces found";

this checks for a single blank space or a tab. hope this is what u were looking for.
Note the space before \t.

If you are looking for ANY whitespace character, then use \s:

if (preg_match("/\\s/",$u_name))
    print " Whitespaces found";
else
    print "No whitespaces found";

LOL... BuzzLy, I see that whole "I can't find a decent job and the newb got a good one with no knowledge" post over in Coding is eating at you... I take it the job hunt didn't go too well today... I am hiring an IS Professional (PC/LAN/WAN Technician)... PM me if you want the email addy to sub your resume to... Oh yeah, we don't have a relocation package, and it isn't a telecommute, so I hope you live near me :rolleyes:
