Writing to a file. (PHP)

It's possible to ammend data within a file vs. just adding data to the beginning or the end of the file? Mean to change something in the "middle" of the file.

Thanks.

Hi. Here's one way to do it.

PHP Code:


		
			
<?php



$filename = "filename.ext";

$oldtext = "old text";

$newtext = "new text";



if (is_writable($filename)) {

    $buffer = implode("", file($filename));

    $buffer = str_replace($oldtext, $newtext, $buffer);

    $handle = fopen($filename, "wb");

    fwrite($handle, $buffer);

    fclose($handle);

}

else {

    clearstatcache();

    echo "Cannot write to ".$filename." - Check permissions.";

}



?>
