What common syntax errors can lead to unexpected 'else' errors in PHP code?

Common syntax errors that can lead to unexpected 'else' errors in PHP code include missing semicolons at the end of lines, missing closing parentheses or curly braces, and incorrect indentation. To solve this issue, carefully check the syntax of your code, ensure all statements are properly terminated, and properly nest your if-else statements.

// Incorrect code with missing semicolon and incorrect indentation
if ($condition) {
    echo "Condition is true"
} else {
    echo "Condition is false";
}

// Corrected code with proper syntax and indentation
if ($condition) {
    echo "Condition is true";
} else {
    echo "Condition is false";
}
