What is the error message "Parse error: parse error, unexpected T_VARIABLE" indicating in the PHP script?

The error message "Parse error: parse error, unexpected T_VARIABLE" indicates that there is a syntax error in the PHP script, often caused by a missing semicolon or a misplaced variable declaration. To solve this issue, carefully check the code for any syntax errors and ensure that all variables are properly declared and used.

// Incorrect code causing the parse error
$variable = "Hello World"
echo $variable;

// Corrected code with the missing semicolon added
$variable = "Hello World";
echo $variable;
