Check Text File For Email {if} {else}

[damanic]

Hi there,

I have a problem getting a script to check a text file for an email.

This is what I have:

<?php
$email = '[e-mail]';
// Check Subscription Status for General & Shop
$newfile = fopen("/files/email.list", "r");
    while(!feof($newfile))
   {
     $duplicate = fgetss($newfile, 255);
     // is email address submitted already on file?
        if(eregi("$email", $duplicate))
       {
         print("<p><strong>You are subscribed as $email </p>");
       }
   }
?>

The problem is that I would like to include an else statement but cant do it without errors and strange results.

I tried

    

while(!feof($newfile))
   {
     $duplicate = fgetss($newfile, 255);
     // is email address submitted already on file?
        if(eregi("$email", $duplicate))
       {
         print("<p><strong>You are subscribed as $email </p>");
       }
       else
      { 
       print("<p><strong>$email is not subscribed to this list </p>");
      }
   }

But that started off some crazy looping. It didnt like it at all. I cant use exit; as I have other code that needs to be processed after this script.

Hows it done?

You can use break; to break from while loop:

$error = false;
while(!feof($newfile)) {
	$duplicate = fgetss($newfile, 255);
     // is email address submitted already on file?
	if(eregi("$email", $duplicate)) {
		echo "<p><strong>You are subscribed as $email </p>";
		$error = true;
		break;
	}
}

if ($error == true) {
	echo "<p><strong>$email is not subscribed to this list </p>";
}

BTW, you should use strstr or even better strpos function to find if the email exists. Eregi is quite slow and you better use those that I mentioned..

try something like this:

<?php

$email = "[e-mail]";

$file = file_get_contents("/files/email.list");

if (strpos($file, $email)) {

	echo "The e-mail <b>$email</b> was found!";

} else {

	echo "Nope, nothing was found!";

}

?>
