Create a cron schedule for php run

I wanted to insert a record to database every minute. this is the my php script.

<?php

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

$user="ppuser";
$password="ppuserbb";
$database="test";
$host="192.168.1.22";

$names=array('test1','test2','test3','test4');

$id=array_rand($names);
$name=$names[$id];



mysql_connect($host,$user,$password);
@mysql_select_db($database) or die( "Unable to select database");

$sql="INSERT INTO `crontest` (
        `name` ,
        `insert_time`
        )
        VALUES ('".$name."', NOW());";
 mysql_query($sql);
 mysql_close();

?>

then open the crontab in linux.

run  crontab -e on terminal. then add below line to crontab.

*/1 * * * * php /opt/lampp/htdocs/test2/sanjicron.php

1st *: Minute (0-59)
2nd *: Hours (0-23)
3rd *: Day (0-31)
