How can proper variable naming conventions prevent syntax errors in PHP?

Proper variable naming conventions in PHP can prevent syntax errors by ensuring that variables are named in a way that follows the rules of the language. This includes using only letters, numbers, and underscores in variable names, starting with a letter or underscore, and avoiding reserved words. By adhering to these conventions, developers can avoid common syntax errors that may occur due to incorrectly named variables.

// Incorrect variable naming causing syntax error
$2myVariable = "Hello World";

// Correct variable naming to prevent syntax error
$myVariable = "Hello World";
