strtolower (PHP 3, PHP 4, PHP 5) strtolower -- Make a string lowercase Descriptionstring 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.

If you're considering using the below unhtmlentities function from phpContrib, I would suggest this one as an alternative:
<?php
function unhtmlentities($string)
{
$string = preg_replace('~&#x([0-9a-f]+);~ei', 'chr(hexdec("\\1"))', $string);
$string = preg_replace('~&#([0-9]+);~e', 'chr(\\1)', $string);
$trans_tbl = get_html_translation_table(HTML_ENTITIES);
$trans_tbl = array_flip($trans_tbl);
return strtr($string, $trans_tbl);
}
?>
That was copied exactly from the html_entity_decode manual page. It'll handle numeric entities correctly, the below function won't.

Nifty? :D
<?php
function is_lowercase ($str){
return ($str == strtolower ($str));
}
?>

There's a ucfirst "function" to make the first character uppercase, but there's no "lcfirst" function to make the first character lowercase. Here's my own code to accomplish this.
<?
function lcfirst($str) {
return strtolower(substr($str, 0, 1)) . substr($str, 1);
}
?>
I found this particularly useful for generating XML nodes with the Reflection class.

To do case insensitive comparisons in a database, strtolower() can be a quick and dirty solution:
$Sql = "SELECT * FROM tablename WHERE LOWER(column_name) = '".strtolower($my_var)."'";

<?php
$b=html_entity_decode(strtolower(htmlentities($a)));
?>
