Entering the duplicate record

[sandy1028]

hi,

 

The code inserts the duplicate record when i am writing to text file.

 

<?

$name=$_POST['name'];

$address=$_POST['address'];

$age=$_POST['age'];

$email=$_POST['email'];

$mobile=$_POST['mobile'];

$residence=$_POST['residence'];

 

        $fp= fopen("phonedb.txt","r") or die("can't open file");

 

$lines = file('./phonedb.txt');

          foreach ($lines as $line) {

            $text_line = explode(":" , $line);

if($text_line[4]== $mobile)

{

fclose($fp);

die();

}

}

 

$fp= fopen("data.txt","a") or die("can't open file");

$data="$name : $address : $age : $email : $mobile :  $residence\n";

fwrite($fp, $data);

fclose($fp);

 

Still the duplicate record is getting inserted.

Can anyone find out the problem and help with this

 

 

Regards,

Sandy

I think in file it is difficult to control the duplication but if u use the database concept then it would be easier.

is there a reason why you are not using the same file??? - there are two file pointers in that script.

Hi,

 

To check from the txt file how to compare the values after explode

$lines = file('./phonedb.txt');

$fp= fopen("phonedb.txt","r") or die("can't open file");

foreach ($lines as $line) {

      list($name1,$address1,$age1,$email1,$mobile1,$residence1) = explode(":" , $line);

}

if($mobile1 != $mobile){

$fp= fopen("phonedb.txt","a") or die("can't open file");

fwrite($fp, $data);

fclose($fp);

}
