What could be causing the "Parse error: parse error, unexpected T_VARIABLE" in the PHP code provided?

The "Parse error: parse error, unexpected T_VARIABLE" in PHP code typically occurs when a variable is used incorrectly, such as missing a semicolon at the end of a line or using a reserved keyword as a variable name. To solve this issue, carefully check the variable declarations and ensure they follow the correct syntax rules.

// Incorrect code causing "Parse error: parse error, unexpected T_VARIABLE"
$var1 = "Hello"
$var2 = "World";

// Corrected code with semicolons added to the end of variable declarations
$var1 = "Hello";
$var2 = "World";
