Are there specific resources or guides available for troubleshooting common PHP syntax errors, like unexpected elseif statements?

One common PHP syntax error is the "unexpected elseif" statement, which occurs when an elseif statement is used without a preceding if statement. To solve this issue, ensure that each elseif statement is preceded by an if statement. This error can also occur if there is a missing or misplaced curly brace in the code.

<?php
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} elseif ($number < 5) {
    echo "Number is less than 5";
} else {
    echo "Number is equal to 5";
}
?>
