Balto

well, mainly because I want the same code to be able to sit on mysql and odbc databases. now the functions follow the same paradigm but have different names. I figured that a layer of abstraction would help provide independency from the underlying engine. anyway, since resource variables are just pointers to resources, they must be the easiest thing to pass to functions, like many other languages. it is strange that PHP doesn't allow them to be declared. I wonder if there is a reason or a workaround.

Dear all, the following PHP script produces the warnings Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in fetchArray function Warning: mysql_free_result(): supplied argument is not a valid MySQL result resource in releaseQuery function is there a way to tell these function that we are passing a resource for them? thanks, balto function connectMydb(){ $link=mysql_connect('localhost', 'mydb', 'pass') or die ('could not connect to Database'); mysql_select_db("mydbases"); return $link; } //--------------------------------- Query ------------------------------------ function queryMydb($stmt){ return mysql_query ($stmt) or die (mysql_error()); } //------------------------------- Release Query --------------------------- function releaseQuery($query){ mysql_free_result ($query); } //----------------------------- fetch a row --------------------------------- function fetchArray ($query){ return mysql_fetch_array($query, MYSQL_ASSOC); } $link = connectMydb(); $result=queryMydb("select * from mytable"); $row=fetchArray($result); //.... do something with data.
