Case sensitive variable comparison

[dmccabe]

I have the following code:

 

$newfirstletter = substr($row['name'], 0,1);
	if ($newfirstletter != $firstletter) {
		$firstletter = $newfirstletter;

 

It is taking the first letter of a word from the db and comparing it with the variable $newfirstletter then if they are different creating a new header.

 

However if the letter is the same but the case is different it creates a new header anyway, how can I make it case-insensitive.

use the preg_match() function

I'd do something like this:

 

$str = 'hello';
$char = 'H';
if(strcasecmp($str[0],$char) == 0){
echo 'true';
}else{
echo 'false';
}

Nice, never seen that function

[dmccabe]

Excellent thanks I will give the strcasecmp function

running strtolower/upper on both vars will work as well.

running strtolower/upper on both vars will work as well.

 

though slightly slower unfortunately (we had a huge thread testing the speeds before of these same methods, hah).
