rtrim() and ltrim()

I understand that rtrim() strips all of the white spaces from the end of a string, and ltrim() strips all of the white spaces from the beginning of a string. But if there are white spaces in the middle of a string will it strip them also? I don't want this to happen....

Would you use the functions like this:

PHP Code:


		
			


$myvariable = $rtrim($myvariable);

$anotherVar = $ltrim($anotherVar);



echo $myvariable;

echo $anotherVar;

Nope, and the manual pages are pretty explicit about this.

The $ character denotes a variable and the *trims are functions.

And if you want to strip both leading and trailing white space there's plain old trim.

PHP Code:


		
			
$myvariable = trim($myvariable);
