strtoupper -- Make a string uppercase

Description

Note that 'alphabetic' is determined by the current locale. For instance, in the default "C" locale characters such as umlaut-a (ä) will not be converted.

Example 1. Strtoupper() example


$str = "Mary Had A Little Lamb and She LOVED It So";
$str = strtoupper ($str);	
print $str; # Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO

See also strtolower() and ucfirst().

If you are unable to change your default config to support special chars such as umlauts, then use strtr to translate upper/lower versions.

<pre>$string=strtr("ÄÖÜ","äöü");</pre>

A good example of this strtr use for spanish is:

$string = strtr($string,"&aacute;&eacute;&iacute;&oacute;&uacute;&ntilde;&uuml;","&Aacute;&Eacute;&Iacute;&Oacute;&Uacute;&Ntilde;&Uuml;");

You can swap them to translate from uppercase to lowercase or the other way around.
