How can the error "Parse error: parse error, unexpected T_VARIABLE" be resolved in PHP code?

The error "Parse error: parse error, unexpected T_VARIABLE" typically occurs when there is a syntax error in the PHP code, often caused by missing semicolons, parentheses, or curly braces. To resolve this issue, carefully review the code around the line mentioned in the error message and ensure that all syntax elements are correctly used.

// Incorrect code causing the parse error
