Examples

Check if the response code is informational

This code checks if the response code 100 is informational.

$response_code = 100;
if (is_info($response_code)) {
    echo "The response code is informational.";
} else {
    echo "The response code is not informational.";
}

Handle different response codes

This code handles different response codes and checks if they are informational.

$response_codes = [100, 150, 199, 200, 404];
foreach ($response_codes as $code) {
if (is_info($code)) {
echo "The response code $code is informational.\n";
} else {
echo "The response code $code is not informational.\n";
}
}

Function to categorize response codes

This code defines a function to categorize HTTP response codes and uses is_info() to determine if a response code is informational.

function categorize_response_code($code) {
    if (is_info($code)) {
        return "Informational";
    }
    // Other conditions to categorize response codes
}
$response_code = 150;
$category = categorize_response_code($response_code);
echo "The response code $response_code is $category.";

Logging informational response codes

This code logs informational response codes using is_info() and a custom logging function.

function custom_log($message) {
    // Your custom logging implementation
}
$response_codes = [100, 150, 199, 200, 404];
foreach ($response_codes as $code) {
if (is_info($code)) {
custom_log("Informational response code: $code");
}
}

Filtering informational response codes

This code filters an array of response codes to keep only informational response codes using is_info().

$response_codes = [100, 150, 199, 200, 404];
$informational_codes = array_filter($response_codes, 'is_info');
print_r($informational_codes);
