Question About The Print_R Function

[nomadsoul]

Hi,

In the script on page 5 line 40, in the print_r function's argument, what is the "1" for?

echo '<h3>Array As Is</h3><pre>' . print_r($students, 1) . '</pre>';

 

thanks

If you want to return the information from print_r rather than print it, use TRUE (1 boolean as in this example).

 

echo '<h3>Array As Is</h3><pre>' . print_r($students, TRUE) . '</pre>';

Is working exactly the same way.

Thanks, Antonio. For future reference, this is the kind of question that's very quickly answered by looking up the function definition in the PHP manual.
