Saving php output in a file

I have:

echo"<br>";echo"<br><pre>";print_r($array2);echo"</pre>";
echo"<br>";echo"<br><pre>";print_r($array3);echo"</pre>";
 echo"<br>";echo"<br><pre>";print_r($array4);echo"</pre>";

I need to save what all of these print_r print into a file (without pronting anything in the page).

I know I need to do something like that: 

$f = fopen("file.txt", "w");
fwrite($f, "TEXT TO WRITE");
fclose($f);

But I don't know how to put the contents before in it.

Solution

  • Try this out using the true param in the print_r:

    $f = fopen("file.txt", "w");
fwrite($f, print_r($array2, true));
fwrite($f, print_r($array3, true));
fwrite($f, print_r($array4, true));
fclose($f);
