Is any script that deal with all aspact of dicom viewing in php.

Short answer for @Abhinandan431: there is no single, mature PHP file you can drop in that will fully handle every DICOM feature (compressed transfer syntaxes, window/level, multi‑frame, overlays, etc.). The practical, reliable pattern is to use PHP as the server glue and combine a DICOM toolkit or PACS with a web viewer (client‑side JS). @baig123 is right that solutions exist, but they are usually multi‑component.

A compact workflow that works in production:

1. Accept uploads and store each .dcm file on disk or object storage; keep searchable metadata in MySQL/Postgres rather than storing large BLOBs in the DB.
2. On ingest, extract thumbnails/preview and metadata with a server toolkit such as DCMTK or [GDCM]/dcm4che so you can serve quick previews.
3. For a full viewer, expose the studies via a WADO/WADO‑RS endpoint (or let a lightweight PACS like Orthanc manage files and provide a REST API). PHP can act as middleware that authenticates requests and proxies/asks Orthanc for pixels.
4. In the browser use a JavaScript viewer such as Cornerstone or the OHIF viewer to handle window/level, multi‑frame navigation, and overlays. Those viewers can load DICOM via WADO or PNG/JPEG you generated server‑side.

Troubleshooting and cautions: if images are blank, check transfer syntax (JPEG2000/JPEG‑LS require decompression), photometric interpretation, and byte order. Multi‑frame DICOMs require frame selection; window/level is best done client‑side for performance. Secure PHI with TLS, auth checks, and consider anonymization for non‑production. For scalable setups prefer Orthanc/dcm4che + JS viewer rather than trying to implement decoding entirely in PHP.
