mysql - PHP Dynamic insert function is inserting duplicate rows -


i have created function inserts data mysql database dynamically avoid code repetition :

function insert($table, $data) {     // connection    global $db;      if(!is_array($data)) die("error : second parameter must array of keys , values");      $keys   = array_keys($data);     $values = array_values($data);      // sql query     $sql = "insert `$table` (";     // if more 1 column     if(count($data) > 1)     {          for($i = 0; $i < count($data) -1; $i++)          {             $sql .= "`$keys[$i]`, ";          }           $sql .= "`" . end($keys) . "`) values (";           for($i = 0; $i < count($data) -1; $i++)          {             $sql .= ":$keys[$i], ";          }          $sql .=":" . end($keys) . ")";      }else{ // 1 column          $sql .= "`$keys[0]`) values(:$keys[0])";     }      // make keys named placeholders     $binds = array_map(function($elem){         return ":".$elem;     }, $keys);       // combine placeholders values     $binds = array_combine($binds, $values);       $stmt = $db->prepare($sql);     return $stmt->execute($binds) ? true : false; }

so later on can insert data :

echo insert("users",[     "name"  => "timino",     "email" => "admin@timino.io" ]); // result 1 inserted or 0 failed

however inserting duplicate rows ?? when debug code looks okay

echo $sql;  //insert `users` (`name`, `email`) values (:name, :email) print_r($binds) // array (     [:name] => timino     [:email] => admin@timino.io )

what doing wrong ?

note : have updated code procedural make easy 1 test !

are executing code in index.php?

echo $db->insert("users",[     "name"  => "timino",     "email" => "admin@timino.io" ]); // result 1 inserted or 0 failed

it might not code issue.

i had similar issue testing insert in index.php, , had rule in .htaccess redirect not found files index.php. , when browser tries locate favicon, it's redirected index.php execute code once again.

if that's case, can try moving code file test.php , call domain http://localhost/test.php , check if it's still duplicating.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
