How can syntax errors like unexpected T_CASE be resolved in PHP code?

To resolve syntax errors like unexpected T_CASE in PHP code, you need to carefully check your switch statement for any missing or misplaced curly braces, colons, or semicolons. Make sure each case statement is followed by a colon and ends with a break statement. Additionally, ensure that the switch statement is properly closed with a closing curly brace. Example PHP code snippet:

switch ($variable) {
    case 'value1':
        // do something
        break;
    case 'value2':
        // do something else
        break;
    default:
        // default case
        break;
}
