What best practices should be followed when using z-index in PHP to avoid display issues?

When using z-index in PHP to control the stacking order of elements, it is important to ensure that the z-index values are properly assigned to avoid display issues such as elements overlapping incorrectly or not appearing as expected. To prevent problems, it is recommended to use z-index values consistently across all elements and avoid assigning extremely high or low values that could cause unexpected behavior. 

// Example of setting z-index values in PHP
echo '<div style="z-index: 1;">Element 1</div>';
echo '<div style="z-index: 2;">Element 2</div>';
echo '<div style="z-index: 3;">Element 3</div>';
