Script that pulls a webpage

There are some examples here:

http://us4.php.net/function.file

<?php
// Get a file into an array.  In this example we'll go through HTTP to get
// the HTML source of a URL.
$lines = file('http://www.example.com/');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
   echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

// Another example, let's get a web page into a string.  See also file_get_contents().
$html = implode('', file('http://www.example.com/'));
?>

venkat

file_get_contents()  -- Reads entire file into a string just like file()

Why does this str replaces not work?  I am using this for testing purposed to learn how to do this.  I maybe going at it all wrong

<?php
// Get a file into an array.  In this example we'll go through HTTP to get
// the HTML source of a URL.
$lines = file('http://www.chaoticage.com/scores_1.php');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
   
      if(strstr($line,'<tr><td>')) {
            
            #str_replace("this","that",$line);
            substr_replace('<tr><td>',"",$line);
            #str_replace("","",$line);
            substr_replace("</td><td>",";",$line);
            substr_replace("</td><td style=\"text-align: left;\">",";",$line);
        substr_replace("</td><td style=\"color:#FF0000;\">",";",$line);
            echo($line);
            #exit;
          #echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";      
      }
}
?>

I have also tried str_replace and that does not work either :-(  any ideas?

oh gosh,  that was a bone head mistake...  I will let you know how it goes
