Differences between passing variable parameters to functions in JS and PHP instance code

The difference between passing variable parameters to functions in JS and PHP is the instance code. For more information, see. # JS call function to pass variable parameters

The code is as follows:

Script
Function test (){
For (var I = 0; I <arguments. length; I ++ ){
Alert (arguments [I]);
}
}
// Call a function
Test (1, 2, 3, 'ABC ');
Script

# PHP call the function to pass variable parameters

The code is as follows:

// Method 1
// Receives a series of parameters and outputs them one by one
Function show_params (){
// Obtain the number of passed parameters
$ Count = func_num_args ();

// Traverse parameters and output them one by one
For ($ I = 0; $ I <$ count; $ I ++ ){
// Obtain parameters
$ Param = func_get_arg ($ I );
Echo $ param. PHP_EOL;
}
}

// Call a function
Show_params (1, 2, 'apple', 3.14 );

// Method 2
Function show_params (){
// Define an array for storing passed parameters
$ Params = array ();
// Obtain all parameters
$ Params = func_get_args ();
$ Count = count ($ params );
// Traverse and output parameters one by one
For ($ I = 0; $ I <$ count; $ I ++ ){
Echo $ params [$ I];
Echo PHP_EOL;
}
}
// Note: Method 2 is slower than method 1.
