Question about how to retrieve certain part of a text file?

[FoxhoundX]

Okay, I am making a site, not sure about what yet though :p

I have made a simple account registration and login using text files (They are stored in an outside directory), and I have a question (well a couple really).

Say there is an txt file 'UserEmail.txt' When creating an account, it will insert a line.. $user:$email

Is there a way to just recall the email of the user?

Yep. Which one were you thinking of?

😉

[FoxhoundX]

Which one what? O.o

Here is what I was thinking...

$em = $user;
$em .= ':';
$em .= $email;
$em .= ' ';

$filename = "../accountemailss.txt";
$handle = fopen($filename, "r");
$old_content = fread($handle, filesize ($filename));
$handle = null;
$foxcontent = $old_content.$em;
$handle2 = fopen($filename, "w");
$finalwrite = fwrite($handle2, $foxcontent);
$handle2 = null;

But I would want to just take the $email depending on who he is logged in as

How bout file() and arrays?

$filename = "../accountemailss.txt";
$handle = fopen($filename, "r");
$old_content = file($filename);
for ($x=0; $x<count($old_content); $x++) {
   $details=explode(":", $old_content['$x'])
   if $details[0]==$user {
      $new_email=$details[1];
      }
   }

Two questions (It's late, can't think)

What would be the output of the email? $new_email?

and this is to read the email, correct?

[FoxhoundX]

Also, currently the thing will just save with spaces between it

Ie:

Firebird:[e-mail] Bla:[e-mail]

Instead of

Firebird:[e-mail]
Bla:[e-mail]

Is this a problem?

Likely yes, as file would look at newlines, methinks.

It's a sloppy format, I think, though no personal criticism intended. Couldn't ya stick a \n in there somewhere?

As to your other questions, yes, and yes, that's the intent.

[FoxhoundX]

How would I stick a \n?

I get Warning: Unexpected character in input: '\' (ASCII=92) state=1 in c:\program files\easyphp\www\create.php on line 27

using

$uer = $user;
$uer .= \n;

I know my scripts are messy/sloppy/crappily coded, started learning on and off like a month ago :S

Given that

$em = $user;
$em .= ':';
$em .= $email;
$em .= ' ';

is what you do to add names to the file,
change the last line to

$em.="\n";

Each new user/addy pair will be on a newline.....

Get an error..

Parse error: parse error, unexpected T_IF in c:\program files\easyphp\www\member.php on line 27

Line 27: if $details[0]==$user {

if ($details[0]==$user) {

As you said, it was late... 🙂
