How can you concatenate the value of one variable to another variable without turning it into an array in PHP?

To concatenate the value of one variable to another variable without turning it into an array in PHP, you can simply use the "." operator to concatenate the values. This operator allows you to combine strings or variables without creating an array. By using the "." operator, you can easily merge the values of two variables into a single string without any conversion to an array.

$var1 = "Hello";
$var2 = "World";
$concatenated = $var1 . $var2;
echo $concatenated; // Output: HelloWorld
