PHP-MSSQL Database Connection Issue

I'm running a new PHP script on Linux and it's not pulling data correctly from an MSSQL Database. Since the script is new, I'd appreciate some help identifying what went wrong.

Skillsets and Experience Needed:
- Proficiency with PHP and MSSQL databases
- Experience troubleshooting PHP script issues in a Linux environment
- Experience with new script debugging
- Knowledge of database connectivity issues and their solutions
- Ability to communicate complex technical issues clearly
