Hi all!
My eps images are stored in the database and I want to display them on web after converting them into png using PHP. Can someone guide me how to proceed? If possible please share any relevant example.

Using the word "convert" suggests that it's a simple format switch, but
it isn't. EPS is not a bitmap format, it's a vector format that needs to
be interpreted by an apporpriate engine. In other words, you need to
*render* or *raster* the file.
I don't know if anyone took the time to write a decent EPS engine in
pure PHP but, if I recall correctly, the ImageMagick [1] command line
utilities offer some sort of support for PostScript files (though I'm
sure the result is not good). A third-party program is probably your
best chance.

Certainly the Gimp can read postcript and turn it into bitmaps.
So the problem is soluble.
Ghostcript is a possible command line tool
Personally i'd set up a process to trawl through and store each EPS
image as a rasterised one in the database on an 'as needed' basis.

I'd recommend you install ImageMagick (it may already be installed on
the PHP server) and run the "convert" command instead. Just run the
command once for each image and store the resulting PNG image in some
other part of the database.
