How can using arrays instead of individual variables simplify the process of handling global variables in PHP functions?

Using arrays instead of individual variables simplifies the process of handling global variables in PHP functions by allowing you to pass the array as a parameter to the function, rather than declaring each global variable within the function. This makes the code more modular and easier to maintain, as all related global variables can be stored and accessed within a single array. 

// Using arrays to handle global variables in PHP functions

$globalVars = array(
    'var1' => 'value1',
    'var2' => 'value2',
    'var3' => 'value3'
);

function myFunction($globalVars) {
    // Access global variables using the array
    echo $globalVars['var1'];
    echo $globalVars['var2'];
    echo $globalVars['var3'];
}

// Call the function with the global variables array
myFunction($globalVars);
