Hey,
I saw this post earlier on, and then I decided to write a small script so it would be easier to learn off it. Then I realised this post begun like 7 months ago, and you probably already have the soloution. But I thought, hell I whipped up a quick script, maybe it will help someone, and I'll post it anyway. So here you go.
(Note: This doesn't use readfile() anymore, as I don't like it as it goes straight to the output buffer, which means it echoed straight away.)
Code:
<?php
// Very BETA file manipulation in php.
// Edit before any commercial use, just made for an example.
// You would have to add support for CHMOD and make a login scheme to protect files.
// Writing to the file.
if ($_POST["action"] == "update" && !empty($_POST["fcontents"]) && !empty($_POST["file"])) {
if(!$fp=@fopen($_POST["file"],"wb")) { // Opens for writing, binary flag is for windows support.
echo "Failed opening ".$_POST["file"]." for writing. This may not be writable.";
}
else {
if (!@fwrite($fp,$_POST["fcontents"])) { // If doesn't write contents/
echo "Failed Writing to ".$_POST["file"];
}
$_GET["file"]=$_POST["file"];
}
}
// Reading The File
if (!empty($_GET["file"])) {
$fp=@fopen($_GET["file"],"r");
if (!$fp) {
echo "Failed to open file.";
}
else {
while(!feof($fp)) { // While not at EOF
$contents.=fgets($fp,4096); // Get contents.
}
$contents=htmlspecialchars($contents); // We need to change tag (< and >) to there html entities, so it will work.
echo "<form name=\"file\" method=\"post\" action=\"".$GLOBALS["PHP_SELF"]."\">";
echo "<input type=\"hidden\" name=\"file\" value=\"".$_GET["file"]."\">";
echo "<textarea name=\"fcontents\" cols=\"50\" rows=\"20\">";
echo $contents;
echo "</TEXTAREA><br>";
if (is_writeable($_GET["file"])) { // If file can be edited, add an update button.
echo "<input type=\"submit\" name=\"action\" value=\"update\">";
}
else { // Else tell them they cannot update it.
echo "This file is not writable.";
}
echo "</form>";
}
fclose($fp); // Close file.
}
// Directory Listing.
$dir=opendir("."); // Open current dir.
echo "<table>";
echo "<tr><td>Filename</td><td>Filesize</td></tr>";
while (false !== ($file = readdir($dir))) { // A loop to collect all files, strange looking loop is needed.
if (!is_dir($file) && is_readable($file) && !is_executable($file)) { // If the selected file is not a directory, executable and is readable.
echo "<tr><td><a href=\"".$_GLOBALS["PHP_SELF"]."?file=$file\">$file</a></td>";
echo "<td>".filesize($file)."</td></tr>";
}
}
echo "</table>";
?>
