Netbeans is able to mark deprecated functions thanks to PHPDoc, like:


/**
 * 
 * @deprecated Don't use.
 */
function iAmDeprecated() {
	
}

In my styling, the "iAmDeprecated" is stroke, showing it's clearly deprecated.
But NB should also mark the function as deprecated when used:

echo iAmDeprecated();

Here, NB can do auto-completion (iAmDe + Ctrl&Space shows "iAmDeprecated" which is marked as deprecated) but the function usage is not stroke, meaning it's hard to spot usage of deprecated functions.

NB does so in Java code (the usage of a deprecated class/method is styled like a deprecated element), but not in PHP.

-------------
Show case:


/**
 * This function declaration is well styled
 * @deprecated Don't use.
 */
function iAmDeprecated() {
	
}

// This usage should be styled too
echo iAmDeprecated();
