title: insert multiple rows at once in a MySQL database
body: <p>I can't get PHP to insert multiple rows at once in a MySQL database. </p>
  
  <p>I use the <code>$sql = "INSERT INTO database (a,b,c,d,e) VALUES ('$a', '$b' ,'$c', '$d', '$e')";</code></p>
  
  <p>I want to insert 5 rows at a time in the database, but it only inserts every 5th record. </p>
  
  <p>For example: 
  <code>1. AA 2. AB 3. AC 4. AD 5. AE</code></p>
