regarding print_r()

[Sachin Raut <imsachinraut@xxxxxxxxx>]

Hello,


I am trying to print following array using print_r(), but it appends number
"1" to the output. Can someone pls tell me what is the issue here or is
there any setting i need to do in PHP.


Thanks

<?php

 $a[]="Paris";

$a[]="London";

 echo print_r($a);

?>


Output :

Array ( [0] => Paris [1] => London ) 1
