Hi there,
I am not a php expert, but worked with C, C++, Perl and Java systems working with Oracle database.
Oracle 10g is very flexible and advanced in term of LOBs and CLOBs (you can retrive CLOBs like any other type, can create indexes on CLOB columns and all string functions can work with CLOBs).
When we retrive Oracle CLOB into another language, we need to look at the facilities provided by driver software interacting with Oracle.
In Oracle, you can simply do 'select clob_column from table'. Question is, how the php driver can handle that CLOB data? Can you create a ref cursor and retrive the data? can you create a stream of data and extract the clob (like in C)? or can you simply create a php veriable of unlimited size and select the clob into it (like in Perl)?

Please let us know which solution did you implement.
