When dealing with user input, you will often come across people who keep their Caps Lock key permanently enabled, which can make reading what they write difficult on the eye. It also looks like they are shouting. To solve the problem, we can writhe a simple PHP script which with different modes for case manipulation.

function Convert($text,$mode="")
{
if($mode == "ac")
return strtoupper($text);
else if($mode == "al")
return strtolower($text);
else if($mode == "cew")
{
$text = explode(" ",$text);
foreach($text as $t)
$temp .= ucfirst(strtolower($t))." ";
return $temp;
}
else if($mode = "ces")
{
$text = explode(".",$text);
foreach($text as $t)
$temp .= ucfirst(ltrim(strtolower($t))).".";
return $temp;
}

return $text;
}

Here what it does:
$text is the must be a string
$mode is the mode of capitalization, by default it is set to “” and if you didn’t give it a value then the script will just return the $text unchanged.
Modes:
“ac” means “all capitalized” capitalizes every letter.
“al” means “all lower” converts all the letters to lower case.
“cew” means “capitalize every word”, each new word is being capitalized.
“ces” means “capitalize each sentence”, each new sentence is going to be capitalized.
Usage:
Convert(“XAXAXA I AM SHOUTINT”,”cew”)
Now the guy is not shouting.
