Writing/Reading Txt files

dniezby

I need to create a script that will receive data from a variable.
open (or create if it doesn't exist) the text file and enter the information into the text file.

Then I have another program that has to read the contents of that file and output it to screen.

Here is what I have:

/* Take the contents of the variable $update and write it to 
    text.txt  */
$update=fopen("text.txt","w+");
fwrite($update);
fclose($update);

Maybe you should read up on the fwrite() function:

didn't really help

How did it not help?

You obviously arent able to deal with writing to 1 file, so learn that first.

Then you can learn to work with 2 files.

No I'm not...that's why I'm here...To learn how.

I've been using PHP for about 3 weeks now.

I only need to write to the file.

Then another program is going to open that same file and read it.

Try...

write.php

<?
$var = 'some stuff you want into the textfile';
$TFile = 'file_you_want_to_write_to.txt';
if( !file_exists( $TFile ) )
{
	$fp = fopen( $TFile, 'a+' );
	fwrite( $fp, $var );
	fclose( $fp );
}
else
	die( 'The file already exists.' );
?>

read.php

<?
$TFile = 'file_you_want_to_read.txt';
$TContent = nl2br( implode( '', file( $TFile ) ) );
echo $TContent;
?>
