Oracle - mostrar en web.php campo tipo CLOB

Tengo una tabla con un campo tipo CLOB y lo quiero mostrar en mi pagina web, trabajo con php. Como podria hacer eso?

Yo tengo un proceso que lo muestra en ASP, las funciones a las que llamas son exactamente la mismas solo tienes que cambiarlas para la sintaxis de PHP.

- CLOBRead - ASP/VBScript function reads CLOB data
' - This ASP function reads a CLOB (character large object field) from your Oracle table.
' - You must specify the Oracle table, column name, where clause, and DSN string.
' - Table: name of Oracle table where your data resides.
' - Column: name of column (with a datatype of CLOB) in your Oracle table where your data resides.
' - Where clause: what you would specify in your SQL call to get your data, such as (select lots_of_customer_info_columnname from customer_table where) "CustomerID='123456'"
' - DSN: data source name. Should be either:
' - 1. application("CustomerDB_DSN") (if you're using global.asa in the root path of your webserver)
' - 2. "DRIVER={Oracle ODBC Driver};DBQ=ora.domain.com;UID=userid;pwd=password"
' - Call using:
' - strReturnString=CLOBRead(strTable, strCLOBColumn, strWhereClause, strDSN)
' - Example:
' - strBigOracleString=CLOBRead("customer_table", "lots_of_customer_info_columnname", "CustomerID='"&strCustomerID&"'", application("CustomerDB_DSN"))
' - Note: This function returns only one string (at a time).

function CLOBRead(strTableCR, strCLOBColumnCR, strWhereClauseCR, strConnectionStringCR)
on error resume next

strSQLCR="select dbms_lob.getlength(" & strCLOBColumnCR & ") as CLOBLength from " & strTableCR & " where " & strWhereClauseCR & ";"
conDBOracleGenericReadCR.open strSQLCR, strConnectionStringCR
if err.number<>0 then
