What are common syntax errors in PHP code that can lead to unexpected errors like "syntax error, unexpected 'case' (T_CASE)"?

One common syntax error in PHP that can lead to unexpected errors like "syntax error, unexpected 'case' (T_CASE)" is when there is a missing or misplaced semicolon at the end of a statement. To solve this issue, carefully check the syntax of your code and ensure that all statements are properly terminated with a semicolon.

// Incorrect code with missing semicolon
$variable = 10
switch($variable) {
    case 10:
        echo "The variable is 10";
        break;
}

// Corrected code with semicolon added
$variable = 10;
switch($variable) {
    case 10:
        echo "The variable is 10";
        break;
}
