ereg(); with files?

[JP128]

Ok, I just started with PHP again, and I was wondering how to do ereg(); with files. If anyone can post a sample code that opens a file, and puts all of the contents into a string, so I would be able to read the contents, that would be awesome. I have tried getting my code to work, but no luck...


thanks, johnny



One more thing, why have I had trouble posting? I sometimes get an Access Denied message.....?

hello JP128. Could you be more specific as to what you need to use ereg() for.

[JP128]

I am using ereg() to look at the text of a file just to see if a persons name exists. I need the script to open a file, look at the contents, and see if a name is in there. I am using this as a test to see if a text document can be used as a little database. I have done it before but went away from PHP, and now I am coming back to it. I lost the old script i had... :(

$data = file_get_contents('file');

[a href=\"http://www.php.net/file_get_contents\" target=\"_blank\"]http://www.php.net/file_get_contents[/a]

Well, yea, I can get that part. . . But when ever I put the if() statement in, it always comes back false. here is what I use....

if(ereg($name, $data)){
echo "That name was found... ";
}
else {
echo "That name does not exist. "
}


That is what I am using... I put my name in there, Johnny, and i know for a fact it is in there... but when I search the contents with the if statement it still says it doesn't exist.



Thanks, Johnny

For a simple search like that, you should consider using something else, like strpos() or stripos() if you want it to not be case-sensitive:

[code]if (strpos($data, $name) !== false) {
   // name found
} else {
   // name not found
}[/code]

[a href=\"http://www.php.net/strpos\" target=\"_blank\"]http://www.php.net/strpos[/a]
[a href=\"http://www.php.net/stripos\" target=\"_blank\"]http://www.php.net/stripos[/a]

here is a sample code...

If you want it to be case-insensitive, you might consider using eregi() or stripos()

I dont care if it is case sensative... I am trying to get that script to work. It will always come back false. I don't know what I am supposed to do with it....

[JP128]

[code]<?php
$name = "johnny";
$filename = "test.txt";
$handle = fopen ("test.txt", "r"); //need to remove the spaces ...
$data = file_get_contents ($handle);
if (ereg($name, $handle)){
echo "Yes<br>";
}
else {
echo "No<br>";
}
fclose ($handle);
?>[/code]


That is a sample code

[poirot]

That's wrong, file_get_contents() don't accept a handle as argument.

[code]<?php

$name = "johnny";
$filename = "test.txt";

$data = file_get_contents ($filename);

if (ereg($name, $data)){
   echo "Yes<br>";
} else {
   echo "No<br>";
}

?> [/code]

Thanks... Lol, After I did that it worked. Now I can look more into that stuff.
