When I write a file using PHP,
<?php
header('Access-Control-Allow-Headers: *');
$texttowrite = $_POST['articletext'];
$title = $_POST['title'];
$name = $_POST['name'];
// Illegal characters on Unix and Linux or any *nix server
$illegal = array(" ", "?", "/", "\\", "*", "|", "<", ">", '"');
// Legal characters
$legal = array("-", "_", "_", "_", "_", "_", "_", "_", "_");
// Replace it!
$newtitle = str_replace($illegal, $legal, $title);
$newname = str_replace($illegal, $legal, $name);
$filename = "content/" + $newtitle + "-" + $newname;
$myfile = fopen($filename, "w") or die("Unable to open file!");
fwrite($myfile, $texttowrite);
?>
note: this program is supposed to read output and a file name from POST form data and write it to a server.
it just creates a file called "0" in the root directory of the server's file system. Is there anything that's going wrong?
No errors were generated by the compiler.
String concatenation in PHP is ., not +.
