please help: tricky file generation problem

Hi,

I have a problem with a HTML generator script I am writing. Basically, I run a PHP script in a while loop. The output of this is stored in a file and then using PHP's file functions, this file is written into a HTML file.

The code in my PHP file is fine but there is a problem with the generated HTML.
Firstly, I am passing a value and using ereg_replace to replace the word -track- in the PHP file with this value. This value is a word and it can be of variable length. Now, when say I run through a loop of 10 names, each of different lengths. When I open the generated HTML files I am seeing parse errors that aren't actually correct.

ie - This error is coded into the generated HTML page because it occurred when the PHP script was being run:

PHP Code:


		
			
 Fatal error: Call to undefined function: ifx_fet() in 

c:program filesnusphereapachensdocshorseracingresultsre  buildresultscache.php on line 104

Obviously, ifx_fet() isnt a function. The actual line 104 code in resultscache.php is this:

PHP Code:


		
			
while($row1 = ifx_fetch_row($result1)){

This is an informix DB function and when I run resultscache.php in the browser and not through the generator script, there are no parse errors. Similarly, in one of the other generated HTML files there is this error:

PHP Code:


		
			
 Fatal error: Call to undefined function: ifx_fetch_row_row()



 in c:program filesnusphereapachensdocshorseracingresultsre  buildresultscache.php on line 104

The word that was passed to generate the first file was 13 characters long while the word for the 2nd file was 7 characters long. For some reason, the PHP seems to be getting messed up when it is read into my script.

I use the code below to read a txt file, replace the appropriate words, save it as resultscache.php, run resultscache.php and then save the HTML output of resultscache.php as a HTML file:

PHP Code:


		
			
 $tempfilename = "tempindex.html";

$targetfilename = 

"html/".$startyear."/".$startmonth."/".$startday."/".$track.$startdate.".html";



//put space back in track for DB query

$track = ereg_replace("_", " ", $track);

?>

<html>

<head>

<title>Generating HTML...</title>

</head>

<body>

<p>Generating <?= $targetfilename?>...</p>

<?php



//change the txt file into a PHP file that replaces placeholder text 

with the correct PHP generated Track name (generated from the 

query)

$tempfile = "resultscache.php";

$fp1 = fopen($tempfile, 'w');

$fp = fopen($filepath."resultscache.txt", "w") or die("Couldn't open file"); 

$data = fread($fp, filesize($fp)); 

$data .= fread($fp, 100000); 

$toreplace = "-track-";

$replacewith = $track;

$data = ereg_replace($toreplace, $replacewith, $data);

$toreplace1 = "-date-";

$replacewith1 = $startdate;

$data = ereg_replace($toreplace1, $replacewith1, $data);

$ok = fwrite($fp1, $data);

fclose($fp); 

//generate php file end



//unlink($tempfilename);



$dynpage = fopen($srcurl, 'r');



if(!$dynpage){

    echo("<p>Unable to load $srcurl. Static page "."update aborted!</p>");

    exit();

}



$htmldata = fread($dynpage, 1024*1024);



fclose($dynpage);



$tempfile = fopen($tempfilename, 'w');



if(!$tempfile){

    echo ("<p>Unable to open temporary file");

    exit();

}



fwrite($tempfile, $htmldata);



fclose($tempfile);

$ok = copy($tempfilename, $targetfilename);



unlink($tempfilename);

I am stumped with this and I have a dealdine hanging ove rmy head so any help is appreciated!

Thanks,
Martin

note: there is forward slashes in the rror output but vBulletin removes them.

Other than getting that error in your file output, is the output correct? if so, just suppress the message using '@'...

Hi,

The error means the database query doesnt produce an array of results to loop through making the page a mess so @ wouldnt work.

its a strange problem because it only happens in some files, I am guessing it might be something to do with how the file is being read and then the different lengths of variable name used to replace -track- could be throing it off somehow.

Anyone else got any ideas on this?

Thanks,
Martin
