How can arrays be used as an alternative to dynamically creating variables in PHP?

When you need to dynamically create a large number of variables in PHP, it can become cumbersome and difficult to manage. Instead of creating individual variables, you can use arrays to store and access the data in a more organized and efficient way. By using arrays, you can dynamically add elements, iterate over them, and easily manipulate the data without cluttering your code with numerous variable declarations.

// Dynamically creating variables
$var1 = 'value1';
$var2 = 'value2';
$var3 = 'value3';

// Using arrays as an alternative
$vars = array('var1' => 'value1', 'var2' => 'value2', 'var3' => 'value3');

// Accessing values from the array
echo $vars['var1']; // Output: value1
echo $vars['var2']; // Output: value2
echo $vars['var3']; // Output: value3

// Adding new elements to the array
$vars['var4'] = 'value4';

// Iterating over the array
foreach ($vars as $key => $value) {
    echo $key . ': ' . $value . "\n";
}
