What role do module loading sequences play in resolving errors related to PHP extensions like PECL?

Module loading sequences play a crucial role in resolving errors related to PHP extensions like PECL because the order in which modules are loaded can affect the availability of functions and classes provided by these extensions. To resolve such errors, it is important to ensure that the required PHP extensions are loaded before any code that depends on them is executed.

// Example of ensuring required PHP extensions are loaded before using them
if (!extension_loaded('pecl_extension')) {
    die('PECL extension is not loaded. Please make sure it is enabled in your PHP configuration.');
}

// Code that depends on the PECL extension can now be safely executed
