I am having trouble with naming the function. I have a class and I need 2 functions something like below.
class myclass {
public function tempclass () {
echo "default";
}
public function tempclass ( $text ) {
echo $text;
}
}
When I call
tempclass('testing'); // ( called after creating the object )
function tempclass() is being called how can i have 2 functions with same name but different parameters?
Traditional overloading is not currently possible in PHP. Instead you'll need to check the arguments passed, and determine how you'd like to respond.
Check out func_num_args and func_get_args at this point. You could use both of these internally to determine how you should respond to the invocation of certain methods. For instance, in your case, you could do the following:
public function tempclass () {
switch ( func_num_args() ) {
case 0:
/* Do something */
break;
case 1:
/* Do something else */
}
}
Alternatively, you could provide default values for your arguments as well, and use those to determine how you ought to react:
public function tempclass ( $text = false ) {
if ( $text ) {
/* This method was provided with text */
} else {
/* This method was not invoked with text */
}
}
func_get_args() and func_num_args(). :-)Overloading isn't possible in PHP.
However, for your simple example above, something like this would work:
class myclass {
public function tempclass ($text='Default') {
echo $text;
}
}
