Search web page for string??

[Anon]

I'd like to write a script that would look at a predetermined webpage, such as "http://www.php.net/index.htm" , search for a string, such as a name or certain word, and then continue on from there.

I've been trying to use fopen and fread to load the contents of a page into a string, and then search from there, but I'm having trouble making it work right.

Anyone done something similar to this? Any help would be appreciated.

Hi,

To load a file and put it into a string you could use:

1)

<?
$myfile = "somefile.htm";
$myfilestring = @implode("",file($myfile));
?>

If you simply wants to know wether $substring is a part of $string or not, it's easier to use regular expressions.

<?
if (ereg($searchstring,$myfilestring )) {
// found
} else {
// not found
}
?>

ereg is case_sensitive if you want to search case-insensitive you can use eregi

or

2)

This example search the file without a string

<?
$myfile = file ('http://www.php.net');
while (list ($line_num, $line) = each ($fcontents)) {
$pos = strpos ($line, "my word");
// this returns the position
// do something :-)
}
?>

Hope this helps a little bit

This code gets out of the page the description and the title. If not available it takes the URL and the first part of the text.

$file = fopen("http://".$url, "r");
if (!$file) {
echo "<p>Unable to open remote file.\n";
exit;
}
$line="";
$name="";
while (!feof($file)) {
$line = $line.fgets($file, 1024);
if (($name=="") AND eregi("<title>(.)</title>", $line, $out)) {
$name = $out[1];
}
if (($name=="") AND eregi('<meta NAME="description" CONTENT="([^">])">', $line, $out)) {
$text = $out[1];
}

}
fclose($file);
$name=urlencode(htmlentities($name));
$text=urlencode(htmlentities($text));
if($name==""){
$name=$url;
}
if($text==""){
$text=urlencode(substr(strip_tags($line),1,500));
}
