Question

Documentation is severely lacking on anything to do with stored procedures in mysql with PHP. I currently have a stored procedure that I call via PHP, how can I get the value of an out parameter?

With mysqli PHP API:

Assume sproc myproc( IN i int, OUT j int ):

$mysqli = new mysqli(  'HOST', 'USR', 'PWD', 'DBNAME' ); $ivalue=1; $res = $mysqli->multi_query( 'CALL myproc($ivalue,@x);SELECT @x' ); if( $res ) {   $results = 0;   do {     if ($result = $mysqli->store_result()) {       printf( '<b>Result #%u</b>:<br/>', ++$results );       while( $row = $result->fetch_row() ) {         foreach( $row as $cell ) echo $cell, '&nbsp;';       }       $result->close();       if( $mysqli->more_results() ) echo '<br/>';     }   } while( $mysqli->next_result() ); } $mysqli->close();
