What are the potential licensing issues with using certain fonts in PHP?

When using certain fonts in PHP, there may be licensing issues if the font is not freely available for commercial use. To avoid any legal complications, it is important to use fonts that are licensed for your intended use or to purchase a license for the font. One way to solve this issue is to use web-safe fonts or fonts from reputable sources that provide proper licensing.

// Example of using a web-safe font in PHP
echo "<p style='font-family: Arial, sans-serif;'>This is a sample text using a web-safe font.</p>";
