Merge 2 php scripts - php

Question

I need some help with some php scripting. I wrote a script that parses an xml and reports the error lines in a txt file.
Code is something like this.
<?php
function print_array($aArray)
{
echo '<pre>';
print_r($aArray);
echo '</pre>';
}
libxml_use_internal_errors(true);
$doc = new DOMDocument('1.0', 'utf-8');
$xml = file_get_contents('file.xml');
$doc->loadXML($xml);
$errors = libxml_get_errors();
print_array($errors);
$lines = file('file.xml');
$output = fopen('errors.txt', 'w');
$distinctErrors = array();
foreach ($errors as $error)
{
if (!array_key_exists($error->line, $distinctErrors))
{
$distinctErrors[$error->line] = $error->message;
fwrite($output, "Error on line #{$error->line} {$lines[$error->line-1]}\n");
}
}
fclose($output);
?>
The print array is only to see the errors, its only optional.
Now my employer found a piece of code on the net
<?php
// test if the form has been submitted
if(isset($_POST['SubmitCheck'])) {
// The form has been submited
// Check the values!
$directory = $_POST['Path'];
if ( ! is_dir($directory)) {
exit('Invalid diretory path');
}
else
{
echo "The dir is: $directory". '<br />';
chdir($directory);
foreach (glob("*.xml") as $filename) {
echo $filename."<br />";
}
}
}
else {
// The form has not been posted
// Show the form
?>
<form id="Form1" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
Path: <input type="text" name="Path"><br>
<input type="hidden" name="SubmitCheck" value="sent">
<input type="Submit" name="Form1_Submit" value="Path">
</form>
<?php
}
?>
That basically finds all xmls in a given directory and told me to combine the 2 scripts.
That i give the input directory, and the script should run on all xmls in that directory and give reports in txt files.
And i don't know how to do that, i'm a beginner in PHP took me about 2-3 days to write the simplest script. Can someone help me with this problem?
Thanks

Answer 1

Make a function aout of your code and replace all 'file.xml' to a parameter e.g. $filename.
In the second script where the "echo $filename" is located, call your function.
