PHP writes files--saves user-submitted data to a file in the server

first write the HTML page:

    
 
      Order Page
Jason's Shopping list

then write the server-side script file in PHP processorder.php

     
 
  
     <title>Order results</title>
Jason's Shopping Cart
Order results

 Time of order submission: '. $date. '
'; Echo '
Your specific shopping list is:
';    Get the total quantity of goods $total _qty=0;    $total _qty= $cloths + $shoes + $glasses; Echo ' Total number of items: '. $total _qty. '
'; if ($total _qty==0) {echo ' You have not purchased any items!    '; }else{if ($cloths >0) {echo $cloths. ' Pieces mens
'; } if ($shoes >0) {echo $shoes. ' Pair of shoes
'; } if ($glasses >0) {echo $glasses. ' Pair of glasses
';    }}//Get the total price of merchandise $total _amount=0.00;    Const CLOTHS_PRICE=100;    Const SHOES_PRICE=300;    Const GLASSES_PRICE=28;    $total _amount= $cloths *cloths_price+ $shoes *shoes_price+ $glasses *glasses_price;    $total _amount=number_format ($total _amount,2, '. ', '); Echo '
Total Merchandise: ￥ '. $total _amount. '
'; Echo '
Delivery address: '. $address. '
'; Set the file output content and format $out _put_string= $date. \ t ". $cloths." piece mens \ t ". $shoes." Two Shoes \ t ". $glasses." Pair of glasses \t\ Total Price: ￥ ". $total _amount." Delivery address: \ t ". $address."    \ n ";    Open file, (Append mode + binary mode) @ $fp =fopen ("$DOCUMENT _root/l02/files/orders.text", ' ab ');    Flock ($FP, LOCK_EX); if (! $fp) {echo]
Your order has not been submitted for completion, please try again.
";    Exit    }//Writes data to file Fwrite ($fp, $out _put_string,strlen ($out _put_string));    Flock ($FP, lock_un);    Close file stream fclose ($FP); echo "
Data Save complete
";? >

Finally, the Orders.txt file is generated under the files file, the contents of the file are (can be appended):

The above describes the PHP write file-the user submitted data saved to the server file, including the contents of the content, I hope the PHP tutorial interested in a friend helpful.
