Ask for a piece of code execution result output code written

The following is a PHP code, the main function is to manipulate the database, but based on the $new_data Array (array 1) for database operations, so every time the database operations
The following is the contents of the $new_data Array (array 1) file.

The result is that when the program loop executes, it can be judged that the operation database failed and which one was successful. The program executes multiple database operations within the loop and outputs the output to all successful {"OK": true}, complete failure {"OK": false} Partial failure (verbose output site such as {"Del": false, "Del_err": $u _id| $tasw _id, "up ": false," Up_err ": $u _id| $tasw _id}
Note that the loop will perform multiple deletions, updates, insert database operations, and of course rewrite the code, but the array format is fixed, $new the _data Array (array 1) executes to $u_id= $res [' u_id ']; generates the following $res array (array 2) for easy database operation

foreach ($new _data as $key) {$res = array (); foreach ($key as $itm) {foreach ($itm as $it = $valu) {$res [Shortstr2 ($it)] = $v                Alu        }} $u _id= $res [' u_id '];        $res [' tasw_id ']= $tasw _id;                if ($tasw _p = = ' x ') {//performs the delete operation $TASW _u_id=substr ($e [0],1,strlen ($e [0]);                if (!db_del ($tasw _id, $TASW _u_id)) {$tasw _err[' d_err ']=false;                }else{$tasw _err[' D_ok ']=true;        }} $chk _u_id= $db->firstvalue ("Select COUNT (*) from {$TBI} WHERE u_id= ' {$u _id} ' and t_id= ' {$tasw _id} '");                if ($chk _u_id>0) {//Update unset ($res [' u_id ']); if (! $db->autoexecute ($TBI, $res, ' UPDATE ', "u_id= ' {$u _id} ' and tree_id= ' {$tasw _id} ')") {$TASW _err[                ' U_err ']=false;              }else{$tasw _err[' U_ok ']=true;  }}else{//Insert if (! $db->autoexecute ($TBI, $res)) {$TASW _err                [' I_err ']=false;                }else{$tasw _err[' I_ok ']=true; }        }}
