What role does case sensitivity play in PHP coding, and how can developers avoid errors related to it?

Case sensitivity in PHP coding refers to the distinction between uppercase and lowercase letters in variable names, function names, and other identifiers. Developers need to be consistent with their casing to avoid errors, as PHP is a case-sensitive language. To avoid issues related to case sensitivity, developers should always use the same casing when referring to variables, functions, and classes throughout their code. 

// Example of avoiding case sensitivity issues in PHP
$myVariable = "Hello, World!";
echo $myVariable; // Output: Hello, World!

$myvariable = "Goodbye, World!";
echo $myvariable; // This will throw an error because the variable name is not consistent
