php - Add Web form input to an Array -


i cannot figure out how go keeping data saved on $myarray after hitting save. everytime that, replaces other input.

i need able save user enters , save in text file. keep saving data on array , update file well.

any suggestions? 

<!doctype>         <html>         <body>             <form action="list.php" method="post">             name: <input type="text" name="name[]" /><br />             email: <input type="text" name="name[]" /><br />            <input type="submit" name="save" value="submit" /><br />         <?php             $myarray = array();          if (isset($_post['save']))         {             array_push($myarray,$_post['name']);         }          print_r($myarray);         ?>         </body>         </html>

every time user hits submit, there new request sent script. variable $myarray created on first line of php code, , empty array.

variables not persist across requests. suggest use either cookie, or session variable this.

example of latter here:

<?php session_start(); // has done before data sent client session_regenerate_id(); // practice prevent session hijacking ?> <!doctype> <html> <body>     <form action="list.php" method="post">     name: <input type="text" name="name[]" /><br />     email: <input type="text" name="name[]" /><br />     <input type="submit" name="save" value="submit" /><br />     <?php         if( !isset( $_session['myarray'] ) || !is_array( $_session['myarray'] ) )         {             $_session['myarray'] = array();         }         if (isset($_post['save']))         {             $_session['myarray'][] = $_post['name'];         }         print_r($_session['myarray']);         // here can write contents of $_session['myarray'] file.     ?> </body> </html>
