How can outdated or incorrect information from older sources impact PHP code development, as seen in the forum thread?

Outdated or incorrect information from older sources can lead to the use of deprecated functions or insecure coding practices in PHP code development. This can result in vulnerabilities, bugs, or compatibility issues in the code. To address this issue, developers should always refer to up-to-date PHP documentation and best practices when writing code. 

// Example of using an outdated function (mysql_query) that should be replaced with mysqli_query

// Incorrect code
$result = mysql_query("SELECT * FROM users");

// Corrected code
$result = mysqli_query($conn, "SELECT * FROM users");
