What is the significance of the unexpected else error in PHP code?

The unexpected else error in PHP code occurs when an else statement is encountered without a corresponding if statement. This error indicates a syntax issue in the code that needs to be corrected by either adding an if statement or removing the else statement. To solve this issue, carefully review the code and ensure that each else statement is paired with a corresponding if statement.

// Incorrect code with unexpected else error
if ($condition) {
    // do something
} else {
    // do something else
} else {
    // unexpected else error
}

// Corrected code without unexpected else error
if ($condition) {
    // do something
} else {
    // do something else
}
