PHP the development team is from the v 5.1 joined a pdo mold piece behind, he defined a lightweight for the PHP interview database of, connecting of consistency, it provided one piece according to interview abstract layer, so, whether what you use is mysql, mssql or other databases or not, you can pass the similar function performance sql operation.Notice, you can not use PDO to expand oneself carry out any database operation, you have to use a database-specific PDO the database server of the driver(drive to PDO of particular database) interview.
　　　　
　　　　The procedure development has an everyone total in the subconscious:Procedure of get stripe to be good friends with towards connecting and, is also say, along with php continuously and forward development, the php authorities is the pdo that destines and expands it and not is provide to morely connect oscular support to the adodb, so say, the procedure development needs everyone’s thought to up carry on renewal and quickly accepts new thing, like always is denounced IE6 similar, although customer’s crowd in nowadays very big, , the Microsoft lately- released operate system can’t definitely is an IE6 again, hereafter can’t provide excessive support to the IE6 again, either.
　　　　
　　　　I belong to an one of the customer of PDO and unify of connect why don’t use, but go to lockstep, I feel each the procedure that greatly open a source should actively of make use of a php new technique, develop a new technique, help PHP continuous of develop before going toward, ex- segment time has a draft call"the IE6 is deathless, the Internet cans not gets a development", probably have a little radical, but I want to speak today, PDO doesn’t live, PHP cans not get a development.
　　　　
　　　　BIWEB sets up station procedure to do at this I relatively applaud, the crest wears pressure, they still just pdo support top and bottom malicious effort, this makes them hereafter expand space will very big, support PHP5.3 even is aftertime the PHP6 will completely have no problem, I hope other source codes can also quickly join this function and bring about a PDO in the PHP industry heat.
