How does the strcasecmp function in PHP impact conditional statements and comparisons?

The strcasecmp function in PHP is used for case-insensitive string comparison. When using this function in conditional statements or comparisons, it ensures that the comparison is not affected by the case of the strings being compared. This can be particularly useful when comparing user input or data where case sensitivity may not be desired. 

$userInput = "Hello";
$compareString = "hello";

if (strcasecmp($userInput, $compareString) === 0) {
    echo "The strings are equal.";
} else {
    echo "The strings are not equal.";
}
