The ReflectionFunction::invokeArgs() function is an inbuilt function in PHP which is used to return the result of the invoked function call.

Syntax:

mixed ReflectionFunction::invokeArgs( array $args )

Parameters: This function accepts a single parameter $args which holds the array of arguments passed to the called function.

Return Value: This function returns the result of the invoked function call.

Below programs illustrate the ReflectionFunction::invokeArgs() function in PHP:



Program 1:




<?php
  
// Initializing a user-defined function
function Company($Company_Name, $Role) {
    return sprintf("%s %s\r\n", $Company_Name, $Role);
}
  
// Using ReflectionFunction() over the specified
// function company
$function = new ReflectionFunction('company');
  
// Calling the invokeArgs() function
$A = $function->invokeArgs(array('GeeksforGeeks',
                 'is a Computer Science Portal.'));
  
// Getting the result of the invoked
// function company
echo $A;
?>
Output:
GeeksforGeeks is a Computer Science Portal.

Program_2:




<?php
  
// Initializing some user-defined functions
function Trial1($First_Args, $Second_Args) {
    return sprintf("%s %s\r\n", $First_Args, $Second_Args);
}
  
function Trial2($First_Args, $Second_Args) {
    return sprintf("%s %s\r\n", $First_Args, $Second_Args);
}
  
// Using ReflectionFunction() over the above
// specified functions 
$function = new ReflectionFunction('Trial1');
$function = new ReflectionFunction('Trial2');
  
// Calling the invokeArgs() function and the
// result of the invoked function company
echo $function->invokeArgs(array('a+a', '= 2a'));
echo $function->invokeArgs(array('a*a', '= a^2'));
?>

Output:

a+a = 2a
a*a = a^2
