a little function/fwrite help...

Ok,

I have a function that pulls info out of DB,

I want this info to be written to a textfile.

Code looks like this..

$myFile = "../sitemap.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = 'displayInfo()';
fwrite($fh, $stringData);
fclose($fh);

PHP:

There is of course an error, $stringdata needs to contain the output from the function or a variable with the function info in...


My eyes hurt..reps going for help !

 

is displayinfo a function in the file ?.

 

Take the single quotes off the function name. Like this:
$stringData = displayInfo();

 

$stringData = 'displayInfo()'; makes it constant.

Correction : $stringData = displayInfo();

Thanks

 

no problem.

 

thanks fot the help, this still does not print the data into the text file. Just a blank t.xt file !

$myFile = "../sitemap.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = displayInfo();
fwrite($fh, $stringData);
fclose($fh);

 

Try this :

echo displayInfo;

What is output ?

 

use file_put_contents() instead.

 

so it would ook like this -

echo file_put_contents("../sitemap.txt","displayUsers()");

 

No.. I suggest you learn php from the basics..

 

echo displayInfo();

Try this man.

 

that just echos out the results to the page...

 

Why do you have an echo here?

Anyway, you need to get the contents (file_get_contents) and then append the new data to the contents then put the contents (file_put_contents).

so somethining like:

<?php
$myFile = "../sitemap.txt";

//get contents
$fh = file_get_contents($myFile);

//append
$stringData = displayInfo();
$fh .= $stringData;

//put
file_put_contents($myFile, $fh);
?>

Code (markup):

But the other method might be better i'm just trying to explain this method

 

thanks for your help, adopting wd_2k6 's method still prints nothing to the text file. Odd as it looks as it should..

 

Do a test to see if displayUsers() is actually returning a value. If it isn't then nothing will be added to the text file.

 

File might be readonly but ya it must produce error / warning.


Following must put contents to sitemap.txt, am not sure if you php distribution has this function.

file_put_contents( "../sitemap.txt", displayInfo() );

PHP:

IMPORTANT

Make sure displayInfo() returns something. If it just displays as its name is, then it means it is not returning anything and file contents will be empty. In such case use following:

<?

	ob_start();

	displayInfo(); //output to be grabbed
	
	$data = ob_get_contents(); //store output to a variable
	
	ob_end_clean();

	file_put_contents( "../sitemap.txt", $data );

?>

No you don't, you can use the FILE_APPEND flag.
