What are some best practices for naming variables in PHP to avoid errors like the one mentioned in the thread?

When naming variables in PHP, it is important to follow certain best practices to avoid errors. One common issue is using reserved keywords or special characters in variable names, which can lead to unexpected behavior or syntax errors. To avoid this, it is recommended to use descriptive names that are clear and meaningful, following a consistent naming convention such as camelCase or snake_case. 

// Incorrect variable naming causing errors
$123variable = "Hello World";
echo $123variable;

// Correct variable naming following best practices
$myVariable = "Hello World";
echo $myVariable;
