What is the significance of "$variable;" in PHP code?

In PHP, the semicolon at the end of a variable declaration is not necessary and can actually cause syntax errors. It is important to remember that a semicolon should only be used at the end of a statement or command in PHP, not after a variable declaration. To fix this issue, simply remove the semicolon after the variable declaration.

// Incorrect usage of semicolon after variable declaration
$variable = "value";

// Correct usage of variable declaration without semicolon
$variable = "value";
