php dynamically creating a file on form submit - php

Question

would any one know how to automatically create a file through PHP so when the tag is clicked it also have the file right now it's only a path which is displayed through a loop. but when you click it there is no file, of course, long story short how can I also create a file too with a loop so all links have files created through fopen or something, just like all of them have paths generated.
<?php
function display_user_docs($doc_array) {
// set global variable, to test later if this is on the page
global $doc_table;
$doc_table = true;
?>
<br>
<form name="doc_table" action="delete_doc.php" method="post">
<table width="300" cellpadding="2" cellspacing="0">
<?php
$color = "#cccccc";
echo "<tr bgcolor=\"".$color."\"><td><strong>Documentations</strong></td>";
echo "<td><strong>Delete?</strong></td></tr>";
if ((is_array($doc_array)) && (count($doc_array) > 0)) {
foreach ($doc_array as $doc) {
if ($color == "#cccccc") {
$color = "#ffffff";
} else {
$color = "#cccccc";
}
echo "<tr bgcolor=\"".$color."\"><td><a class=\"all-doc-link\" href=\"".$doc.".php\">".htmlspecialchars($doc)."</a></td>
<td><input type=\"checkbox\" name=\"del_me[]\"
value=\"".$doc."\"></td>
</tr>";
}
} else {
echo "<tr><td>No documentation on record</td></tr>";
}
?>
</table>
</form>
<?php
}
?>

You can use file_put_contents to create a file in PHP.
It takes two parameters, the first of which is the name of the file to create, and the second of which is the contents to put inside of the file.
For example, if I wanted to make a file called 123.txt which contains hello world, I would do the following:
file_put_contents("123.txt", "hello world");
The filename can contain slashes /, so that you can specify which folder to create the file in. Thus, if I wanted to make my 123.txt file in the folder abc, I can put abc/123.txt as the filename (as long as abc is in the same folder as the PHP script).
You can find more about file_put_contents in the PHP manual.
