This operation affects request-specific session state, cookie settings or the persistence of data between requests.

Before using it, identify which data, connection or runtime state the operation reads or changes. This avoids examples that appear to work but apply to a different context.

What Is setrawcookie() in PHP?


This operation affects request-specific session state, cookie settings or the persistence of data between requests.

Syntax:

<?php

// Signature for reference only
setrawcookie(string $name, [optional] string $value, [optional] array|int $expires_or_options, [optional] string $path, [optional] string $domain, [optional] bool $secure, [optional] bool $httponly) : bool

Parameters and Return Value


  • $name — Required string argument supplied to this operation.
  • $value — Optional string argument supplied to this operation.
  • $expires_or_options — Optional array|int argument supplied to this operation.
  • $path — Optional string argument supplied to this operation.
  • $domain — Optional string argument supplied to this operation.
  • $secure — Optional bool argument supplied to this operation.
  • $httponly — Optional bool argument supplied to this operation.

The declared return type is bool.

Example 1: Basic Usage


<?php

setrawcookie("token", "abc123", ["secure" => true, "httponly" => true, "samesite" => "Strict"]);

This operation affects request-specific session state, cookie settings or the persistence of data between requests.

Example 2: Another Case


<?php

setrawcookie("visitor", "plainvalue", ["expires" => time() + 900, "path" => "/", "secure" => true]);

The second sample illustrates a different way to inspect or handle this operation. Configure the underlying session, socket, key material or connection first.

Practical Example


<?php

setrawcookie("token", "", ["expires" => time() - 3600, "path" => "/", "secure" => true, "httponly" => true]);

The practical example is a teaching scenario. Change sample configuration and credentials before using a similar design in an application.

Important Behavior and Edge Cases


  • Call session configuration functions before starting a session or sending headers; protect identifiers from exposure.
  • Relevant PHP environment: standard. Ensure the required extension and operating-system capabilities are present.
  • Check results and release resources where necessary; successful syntax alone does not guarantee a successful operation.

OptionWhen to Use It

session_startUse this related operation for its different responsibilities; do not assume identical inputs or return values.

Common Beginner Mistakes


MistakeCorrect Approach
Starting the session after response outputConfigure cookie flags and session handling before sending body bytes.
Assuming session_destroy() removes the browser cookieClear session data and expire the cookie using matching scope settings.
Keeping the same session ID after authenticationRotate the identifier when privileges change and use strict mode.

Key Takeaways


  • This operation affects request-specific session state, cookie settings or the persistence of data between requests.
  • Call session configuration functions before starting a session or sending headers; protect identifiers from exposure.
  • Validate inputs and handle failure conditions before integrating this operation into a production workflow.

This operation affects request-specific session state, cookie settings or the persistence of data between requests. Use the appropriate runtime and treat any environment-dependent output as an example, not a guaranteed result.
