Error in script...helppp

[Hanno]

I am new to php.

I would like to write a scripts which takes part of a html file and saves it into another file. I have a script running on my site and I need to modify the output. I don't or can't change the script so I want to do it outside the script.

Below is just and example of how this could work.
However I get an error;
" Warning: Unknown modifier 't' in /home/xcalak/public_html/scripts/mweather/url_modify.php on line 20"

<?php

$url_name = "http://www.xcalak.info/scripts/mweather/mweather.php";
//URL to open

$file_name = "weather.txt";
// File to store result in

$start = '<title>';
$end = '</title>';
// Get text between start and end

$fp = fopen ($url_name, 'r') or die('Unable to open file'.$url_name.' for reading');
while (!feof ($fp))
{
$buf = trim(fgets($fp, 4096));
$cont .= $buf
}

preg_match("/$start(.*)$end/s",$cont,$match);

$result = 'the title of '.$url_name.' is <b>'.$match[1].'</b>';

$file_pointer = fopen($file_name, "w");
// "w" is the mode, or the action we're
// going to perform on the file

fwrite($file_pointer, $result);
// Writing to the file, after truncating it to 0 bytes

fclose($file_pointer);
// close file

print "data written";

?>

Any body know what I did wrong?

Thanks,

Hanno

I think you are missing a / on the end of your preg_match. It should be

preg_match("/$start(.*)$end/s/",$cont,$match);

I think...

Hi,

I tried it but still the same error.....

[jara06]

redo this
$fp = fopen ($url_name, 'r') or die('Unable to open file'.$url_name.' for reading');
while (!feof ($fp))
{
$buf = trim(fgets($fp, 4096));
$cont .= $buf
}

to
$cont = "";
$fp = fopen ($url_name, 'r') or die('Unable to open file'.$url_name.' for reading');
while (!feof ($fp))
{
$buf = trim(fgets($fp, 4096));
$cont .= $buf;
}
$match = array();

I still get that message (the line with preg_match):

Warning: Unknown modifier 't' in /home/xcalak/public_html/scripts/mweather/url_modify.php on line 20

The code now is:
<?php

$url_name = "http://www.xcalak.info/scripts/mweather/mweather.php";
//URL to open

$file_name = "weather.txt";
// absolute path : \home\data.dat

$start = '<title>';
$end = '</title>';
$cont = "";
$fp = fopen ($url_name, 'r') or die('Unable to open file'.$url_name.' for reading');
while (!feof ($fp))
{
$buf = trim(fgets($fp, 4096));
$cont .= $buf;
}
$match = array();

preg_match("/$start(.*)$end/s",$cont,$match);

$result = 'the title of '.$url_name.' is <b>'.$match[1].'</b>';

// End modification

$file_pointer = fopen($file_name, "w");
// "w" is the mode, or the action we're
// going to perform on the file
// Detailed info at end of page

fwrite($file_pointer, $result);
// Writing to the file, after truncating it
// to 0 bytes

fclose($file_pointer);
// everything comes to an end!

print "data written to file successfully";

?>

The code is now,
which looks a bti different.
Doesnt it?
'php' your code '/php' <- use php tag, is second from right when you post

<?php 

$url_name = "http://www.xcalak.info/scripts/mweather/mweather.php"; 
//URL to open 

$file_name = "weather.txt"; 
// absolute path : \home\data.dat 

$start = '<title>'; 
$end = '</title>'; 
$cont = ""; 
$fp = fopen ($url_name, 'r') or die('Unable to open file'.$url_name.' for reading'); 
while (!feof ($fp)) 
{ 
$buf = trim(fgets($fp, 4096)); 
$cont .= $buf; 
} 
$match = array(); 

preg_match("/$start(.*)$end/s",$cont,$match); 

$result = 'the title of '.$url_name.' is <b>'.$match[1].'</b>'; 

// End modification 

$file_pointer = fopen($file_name, "w"); 
// "w" is the mode, or the action we're 
// going to perform on the file 
// Detailed info at end of page 

fwrite($file_pointer, $result); 
// Writing to the file, after truncating it 
// to 0 bytes 

fclose($file_pointer); 
// everything comes to an end! 

print "data written to file successfully"; 

?>

Makes it much easier to see FAULTS and ERROR in syntax of your code.
The COLORS will tell!
I can see no syntax errors, so you must have done some programming mistake
