regex to set var for <title>?

[Anon]

This function checks a URL from user input ($address) and then displays the site, along with it's title, but i need a regex to put the title in a variable ($str) to use later.

This line does not match:
$str = eregi("^{<title>[a-zA-Z0-9]{1,}$</title>$",} $title);

function checkUrl($address) {
$web = @fopen("$address", "r");
if(!($web=@fopen("$address", "r")))
{
echo "Sorry, the site you suggested was not found.";
exit;
}
echo "Here is the site you suggested:<br>";
do {
$title = @fgets($web, 1024);
$title = eregi_replace(".<title>","",$title);
$title = eregi_replace("</title>.","",$title);
static $str;
$str = eregi("^{<title>[a-zA-Z0-9]{1,}$</title>$",} $title);
echo $str;
echo $title;
} while (!feof($web));
fclose($web);
}

Is there a CORRECT way to define this eregi()?

Thanks so much!

for a start, eregi() returns true or false, so $str=eregi(); is not a very helpful statement. i'm not sure about the doubled and $$ either.

try

eregi("<title>(.*)</title>", $title, $chunk);
$str=$chunk[1]

This may work for you after a little tweaking, I did it a little differently but it seems to work

function checkurl($url) {
$url = trim($url);
$lines_array = file($url);
$lines_string = implode( '', $lines_array);
eregi( "<title>(.*)</title>", $lines_string, $title);
if ($title[0] != "") {
print "The title is " .$title[1] ."<br>";
print "the file is ".$lines_string;
}
}

Louie,

Big THANKS! Been working on this issue off and on for a couple days and you got me over the top! Here are my edits:

function checkurl($address) {
global $title;
global $lines_string;
global $lines_array;
$site = trim($address);
$lines_array = @file($site);
if($lines_array == "") {
echo "Sorry, the site you suggested was not found. You may not have included the \"http://\", there could be a typo, or the site is temporarily out of service.<br><br><input type=\"button\" name=\"submit\" value=\"<< Go Back and Check Entry\" onClick=\"window.history.go(-1)\">";
exit;
}
$lines_string = implode("", $lines_array);
eregi( "<title>(.*)</title>", $lines_string, $title);
if ($title[0] != "") {
echo "The title will be listed as: <b> " .$title[1] ."</b><hr>";
} elseif ($title[0] == "") { // testing this cond.
echo "The title will be listed as $address<hr>"; // can't pull the $address var
}
echo "Here is the web site: ".$lines_string;
}

Still fine-tuning to add the eregi() to get the meta description, and handle the empty string when there is no <title> (or entry between <title></title>).

Many, many thanks to you for helping me and others in this forum. Hope I get to your level someday and can help folks as much as you do!
