It also generates HTML output that repeats the form data to the screen.The first parameter of fread() contains the name of the file to read from and the second parameter specifies the maximum number of bytes to read.The following PHP code reads the "webdictionary.txt" file to the end: The feof() function checks if the "end-of-file" (EOF) has been reached.If we open the "newfile.txt" file it would look like this: Now that "newfile.txt" contains some data we can show what happens when we open an existing file for writing.In the following exercise you will create a simple application that allows you to enter data into a form and upload it to a server as a text file, and use another form to view and edit the data on the server. Create the page using the code shown below, and save it with the filename "create_contact.html". It needs to load the text into the textarea, and be able to replace the content in the text file. If we could then put a WYSIWYG editor on the textarea such as it would make a really fantastic basic CMS.
The text file is then used as an 'include' in a single webpage. By putting // in front of $text = fread($file, $size); it now doesn't load the text into the textarea from the text file (which it would need to do to edit the text). On the results page showing what has been submitted (not the text file) it needs a couple of links under the text (because re-entering the url is showing the results and not the form).
The example below creates a new file called "testfile.txt".
The file will be created in the same directory where the PHP code resides: The fwrite() function is used to write to a file.
* more info: @return bool TRUE file created succesfully FALSE failed to create file.
*/ I had some troubles using file_put_contents with an absolute but no canonicalized path (eg.
When the user makes changes to the data and clicks on the "Save changes" button, the amended details are passed to the "save_contact_details.php" script, which writes the new details back to the "mydata.txt" file.
