Difference Between Compiled Libraries and Loaded Extensions

[Rob]

What is the main difference between a library compiled into PHP and
one loaded in PHP.INI as an extension?

The reason I ask is that I'm trying to use FreeTDS as a library to
communicate to MS-SQL. The notes I've read say that FreeTDS has to be
compiled first, then PHP recompiled with support for MSSQL, but I have
no way of recompiling PHP on the operating system I'm using.

How does this differ with using say a DLL in an 'extensions' line.

Nope -- he's using FreeTDS, which is a library required only by the non-
Windows version of PHP's MSSQL extension.

PHP support for MSSQL takes quite a bit of effort to get going on non-
Windows OSes (as does Perl support for MSSQL) -- if your distribution
doesn't include the relevant libraries and you can't recompile PHP, then
you're probably out of luck.

That's what I thought. On the upside, it looks like HP are going to
release a version of PHP based on v5 later this year, so with any
luck, I might just get support for MS-SQL after all.

My real reason for asking the question was to fill in my knowledge gap
about extensions.
