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.

You can use Output Buffering, which comes pretty handy when you want to control what you output in your PHP scripts and how to output it. Here's a small sample:
ob_start();
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>";
$content = ob_get_contents();
$f = fopen("file.txt", "w");
fwrite($f, $content);
fclose($f);
EDIT: If you dont want to show the output in your page, you just have to call ob_end_clean():
ob_start();
//...
$content = ob_get_contents();
ob_end_clean();
//... write the file, either with fopen or with file_put_contents
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);
Another way to save all output to a file using ob_start() (before any output) with callback function:
ob_start(function ($buffer) {
file_put_contents('file.txt', $buffer, FILE_APPEND);
return $buffer; // remove this line if you dont want to show the output
});
