text searching script

mbman

I am an absolute beginner to php, but I need to write a script to search a text file and return all of the email addresses in the file. I have tried the code below, but it doesn't work

<html>
<h1>search program</h1>
<?php

$DOCUMENT_ROOT = $HTTP_SERVER_VARS['DOCUMENT_ROOT'];

$fp = fopen("DOCUMENT_ROOT/../sales.txt", 'r');

while (!feof($fp))

echo (strstr($fp, '@'));

fclose($fp);

?>
</html>

Any suggestions on how to do this?

Thanks

I'm not sure what the file looks like, but assuming there's a space between email addresses and that they don't wrap around multiple lines, something like this will work


$re = "^.[a-zA-Z0-9_.\.-]+@[a-z0-9_]+\\.[a-z]+";

$fp = file("DOCUMENT_ROOT/../sales.txt");

foreach($fp as $index=>$line) {
$entities = split(" ", $line);

for($c = 0; $c < count($entities); $c++) {
if(eregi($re, trim($entities[$c]))) {
  echo($entities[$c]);
}
}

Thanks for the suggestion Kingbear.

I tried the code as seen below, but I get the following error

Parse error: parse error in /home/virtual/site182/fst/var/www/html/string.php on line 22

Here is the code as I tried it:

<html>
<h1>search program</h1>
<?php

$re = "^{.[a-zA-Z0-9..-]+@[a-z0-9]+.[a-z]+";}

$fp = file("DOCUMENT_ROOT/../sales.txt");

foreach($fp as $index=>$line) {
$entities = split(" ", $line);

for($c = 0; $c < count($entities); $c++) {
if(eregi($re, trim($entities[$c]))) {
echo($entities[$c]);
}
}

</html>

I tried to figure out what the problem was to no avail.

There was a bracket missing:

<?php

$re = "^.[a-zA-Z0-9_..-]+@[a-z0-9_]+\.[a-z]+";

$fp = file("DOCUMENT_ROOT/../sales.txt");

foreach($fp as $index=>$line) {
        $entities = split(" ", $line);

    for($c = 0; $c < count($entities); $c++) {
            if(eregi($re, trim($entities[$c]))) {
                    echo($entities[$c] . "<br>");
            }
    }
}



?>

Kingbear,

That is doing the trick. However I have run into another problem. Many of the email addresses are not separated by spaces in the file. The script is finding those that are separated by spaces.

The others have a "|" between them. I have experimented with some way to pick those out, but I have not been able to get it to work.

Any suggestions?

Thanks again for all of the help.

You could try adding after:

$entities = split(" ", $line);

adding:

if(!$entities){ $entities = split("|", $line); }

I think split won't return false unless an error occurs, so I doubt that this would work.

however since split is a regular expression function anyway, you should be able to extend the pattern:

$entities = split("[ |]", $line);

(though I would usually prefer preg_split())

Xblue,

That did it. Thanks for the help.
