How can outdated or incomplete information in PHP documentation impact the development process, and what steps can be taken to address this issue?

Outdated or incomplete information in PHP documentation can lead to confusion, errors, and inefficiencies during the development process. To address this issue, developers should verify information from multiple sources, consult community forums or official documentation updates, and consider using more recent versions of PHP.

// Example of verifying information from multiple sources
// Original documentation states function foo() accepts a string parameter
// Verify this information by checking official PHP documentation and community forums

// If necessary, update code based on verified information
function foo(string $param) {
    // function implementation
}
