default arguments in php in hindi
Default argument in the function
In this video, you will learn how to create a function that has a default value for the argument(s).
A function may define default values for arguments using syntax similar to assigning a variable.
The default is used only when the parameter is not specified.
If you pass null as the parameter then default value is not used.
function bakepizza($size = "medium")
{
return "Making a pizza of $size size.\n";
}
echo bakepizza ();
echo bakepizza(null);
echo bakepizza("small");
The default value must be a constant expression, not (for example) a variable, a class member or a function call.
Note that any optional arguments should be specified after any required arguments, otherwise they cannot be omitted from calls.
Consider the following example:
function makerayta($quantity = 2, $type)
{ return "Making a $quantity plates of $type rayta.";
}
echo makerayta("veg tadka");
