[How Can I......]

[Matthewtung]

I want to write a php script to get a content of a file( which is a php or a normal txt file......) all into a TEXT box....and I can save it afterwards online using $fwrite...I don't have a clue how to start........can someone provide some source or some details about it????

You can start by using either the file() function or a combination of fopen() and fgets().

heres an example of both:

$fp = @fopen("/path/to/file", 'r' )
		         || die( "sorry, I cannot open file\n" );
print "<textarea name=\"text\" rows=\"3\" cols=\"40\">";		  

if ( $fp ) {	// parse file
	while ( $line = @fgets( $fp, 1024 )) {
		// code to parse file here
		print $line . "\n";
	}
}
print "</textarea>";

or with the file() function:

$lines = file("path/to/file")
		  		  or die( "sorry, I cannot open file\n");
print "<textarea name=\"text\" rows=\"3\" cols=\"40\">";
if ($lines) {	// parse file
	for ($i = 0; $i < sizeof($lines); $i++) {
		// loop through lines[] in file
		print $lines[$i] . "\n";
	}
}
print "</textarea>";

the file function is neat cause it breaks the file into any array with each line as an element that you can traverse.....

If you print the contents of a file into a textarea, you should use htmlspecialchars() or htmlentities().

When the used press the Send button, you'll get the content of the textarea with $_POST["the name of the textarea"]. Example:

$usertext = $_POST["contents"];

But you should use stripslashes to convert all \" to ", \' to ', etc...

$usertext = stripslashes($_POST["contents"]);

Then, to write it to a file :

$fp = fopen("/path/filename.extension", "w+");
fputs($fp, $usertext);
fclose($fp);

And that's it !
