What are the potential pitfalls of hiring a web designer with good PHP knowledge for a programming project?

Potential pitfalls of hiring a web designer with good PHP knowledge for a programming project include the designer lacking in-depth programming experience and potentially making mistakes in complex coding tasks. To mitigate this risk, it's important to thoroughly assess the designer's programming skills and experience before hiring them for the project.

// Example PHP code snippet for assessing a web designer's programming skills
if ($webDesigner->hasGoodPHPKnowledge() && $webDesigner->hasExperienceInComplexCodingTasks()) {
    echo "This web designer is suitable for the programming project.";
} else {
    echo "Further assessment of the web designer's programming skills is needed.";
}
