What are common syntax errors in PHP code that can lead to parse errors?

Common syntax errors in PHP code that can lead to parse errors include missing semicolons at the end of statements, mismatched parentheses or curly braces, and using reserved keywords or functions as variable names. To solve these issues, carefully review your code for any missing or misplaced syntax elements and ensure that all variables, functions, and keywords are correctly spelled and used. Example:

// Missing semicolon at the end of the statement
$name = "John"
echo "Hello, $name!"; // Should be "Hello, John!"

// Mismatched parentheses
if ($age > 18 {
    echo "You are an adult.";
}

// Using reserved keyword as a variable name
$class = "Math";
echo "I have a $class class.";
