What are common errors in PHP code that can lead to a "parse error: unexpected T_VARIABLE" message?

A common error that can lead to a "parse error: unexpected T_VARIABLE" message in PHP code is forgetting to properly end a statement with a semicolon. This error occurs when a variable is declared or used without a semicolon at the end of the line. To resolve this issue, make sure to add a semicolon at the end of the line where the variable is declared or used.

// Incorrect code that can lead to a parse error
$variable = "Hello"  // Missing semicolon at the end

// Corrected code
$variable = "Hello";  // Added semicolon at the end
