How can maintaining consistent variable naming conventions improve code readability and help identify errors in PHP scripts?

Maintaining consistent variable naming conventions in PHP scripts can improve code readability by making it easier for developers to understand the purpose of each variable. This consistency can also help identify errors more quickly, as developers can easily spot mistakes such as misspelled variable names. By following a naming convention, such as using camelCase or snake_case, developers can create a standardized way of naming variables that makes the code more organized and easier to maintain.

// Inconsistent variable naming
$firstName = "John";
$last_name = "Doe";
$Age = 30;

// Consistent variable naming
$firstName = "John";
$lastName = "Doe";
$age = 30;
