strtolower

(PHP3 , PHP4 )

strtolower -- Make a string lowercase

Description

string strtolower (string str)

Returns string with all alphabetic characters converted to lowercase.

Note that 'alphabetic' is determined by the current locale. This means that in i.e. the default "C" locale, characters such as umlaut-A (Ä) will not be converted.

Example 1. Strtolower() example


$str = "Mary Had A Little Lamb and She LOVED It So";
$str = strtolower($str);	
print $str; # Prints mary had a little lamb and she loved it so

See also strtoupper() and ucfirst().

If for any reason you are stuck with default config (ie php is hosted for you on an ISP/virtual server rather than your own machine) Then use strtr() to translate umlaut chars into upper and lower case equivalents.

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

Just a note: strtolower($string); does NOT convert ÅÄÖ to åäö.. /Björn.

Forgot to tell you. that bug is only tested on PHP4 Beta 4. (Don't know if it does the same on PHP 3.0.xx)
