What are common syntax errors in PHP scripts that can lead to unexpected $end errors?

Common syntax errors in PHP scripts that can lead to unexpected $end errors include missing semicolons at the end of lines, mismatched parentheses or curly braces, and forgetting to close quotes or brackets. To solve this issue, carefully review your code for any missing or mismatched syntax elements and ensure that all opening brackets, parentheses, and quotes are properly closed.

// Incorrect code with missing semicolon causing unexpected $end error
$variable = "Hello World"
echo $variable;

// Corrected code with semicolon added at the end of the line
$variable = "Hello World";
echo $variable;
