How to pass on a filename as a variable between PHP-files? - php

Question

I have this file1.php:
<?php
// Start the session
session_start();
?>
<?php
$path_to_check = '';
$needle = $_POST['query'];
foreach(glob($path_to_check . '*.xml') as $filename)
{
foreach(file($filename) as $fli=>$fl)
{
if(strpos($fl, $needle)!==false)
{
echo $filename . ' on line ' . ($fli+1) . ': ' . $fl;
}
}
}
$_SESSION["hit"] = $fli;
header('Location: file2.php');
?>
It gets a searchword from a form and searchs for it among all XML-files in the current directory. The XML-files in this directory are only two; 1.xml and 2.xml.
Say I search for a word occuring in 2.xml, then I would like to save "2.xml" as the variable $_SESSION["hit"] and use it in file2.php:
<?php
// Start the session
session_start();
?>
<?php
echo $_SESSION["hit"];
// Load XML file
$xml = new DOMDocument;
$xml->load($_SESSION["hit"]);
// Load XSL file
$xsl = new DOMDocument;
$xsl->load('stylesheet.xsl');
// Configure the transformer
$proc = new XSLTProcessor;
// Attach the xsl rules
$proc->importStyleSheet($xsl);
echo $proc->transformToXML($xml);
?>
Unfortunately,
echo $_SESSION["hit"];
returns just "2" and not "2.xml", so then
$xml->load($_SESSION["hit"]);
will not load the XML-file 2.xml (since the variable just returns 2).
What am I doing wrong here?
Many thanks in advance:-)

<?php
// Start the session
session_start();
?>
<?php
$path_to_check = '';
$needle = $_POST['query'];
foreach(glob($path_to_check . '*.xml') as $filename)
{
foreach(file($filename) as $fli=>$fl)
{
if(strpos($fl, $needle)!==false)
{
echo $filename . ' on line ' . ($fli+1) . ': ' . $fl;
$_SESSION["hit"] = $filename;
}
}
}
header('Location: file2.php');
?>
you need to save the file name in session variable not the line number
