[smartguyin]

i want to convert the first letter in variable in caps.

$var = "abc";

i want to display it like  >>>>  [b]Abc[/b]

And if i want to convert all characters in caps then wht should i do...

[marcus]

[code]
<?php
$var = "abc";

if(!is_numeric($var)){
$words = ucwords($var);
echo $words;
//will show Abc
}else {
die("bad");
}
?>
[/code]

For all caps:

[code]
<?php
$var = "abc";
if(!is_numeric($var)){
$words = strtoupper($var);
echo $var;
//will show ABC
}else {
die("bad");
}
?>
[/code]
