I have set a crawler up in wordpress which grabs stocks data and writes to file which when a user enters a symbol/ticker the variable is read and if it matches the data of a previous crawl for that particular companies data will echo the text file on page, if no data is found the crawler then sets off grabs it and writes to file to save for the next time that symbol is used.

The problem im having is that everything works groovey apart from one thing, when the content is written to file it saves it in the WP root and not inside a subfolder of the theme, basicaly this means that root becomes untidy very quickly and also should the theme be used on another site then its not practical as some important info is missing. I have tried bloginfo and absolute both return the same failure.

This is the code i am using to write to file, like i say it works apart from writing the file into root.

<?php
$CompDetails = "http://www.devserverurl.com/mattv1/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt"; 

if (file_exists($CompDetails)) {}
else
{
include ('crawler_file.php');
$html = file_get_html("http://targeturl.com/research/stocks/snapshot/snapshot.asp?ticker=$Symbol:US");
$es = $html->find('div[class="detailsDataContainerLt"]');
$tickerdetails = ("$es[0]");
$FileHandle2 = fopen($CompDetails, 'w') or die("can't open file");
fwrite($FileHandle2, $tickerdetails);
fclose($FileHandle2);
}
?>

edit below, have also tried this and the same happens as above

<?php

if (file_exists($_SERVER['DOCUMENT_ROOT'] . "/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt")) {}  
else  
{  
include ('crawler_file.php');  
$html = file_get_html("http://targeturl.com/research/stocks/snapshot/snapshot.asp?ticker=$Symbol:US");  
$es = $html->find('div[class="detailsDataContainerLt"]');  
$tickerdetails = ("$es[0]");  
$FileHandle2 = fopen($_SERVER['DOCUMENT_ROOT'] . "/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt", 'w') or die("can't open file");  
fwrite($FileHandle2, $tickerdetails);  
fclose($FileHandle2);  
}  
?>
