What potential issues can arise when using PHP scripts that work on one browser but not on others like Firefox and IE?

Potential issues that can arise when using PHP scripts that work on one browser but not on others like Firefox and IE include browser-specific compatibility issues, differences in handling JavaScript or CSS, and discrepancies in how the browser interprets PHP code. To solve this issue, it is important to ensure that the PHP code is written in a way that is compatible with all major browsers and to test the scripts on different browsers to identify and address any compatibility issues.
