通过CRON加载PHP页面

Question

I am running the following command in cpanel

/ramdisk/bin/php5 -q /home#/username/etc/php.ini /home#/username/public_html/sitename/subfolder/twitter.php

It is supposed to display search results for a certain keyword from twitter. The twitter.php file works just fine...however my impression was that setting the cron job to execute the php file every minute will reload the page with new content.

This isn't happening as twitter.php just remains the same (when viewed in my browser).

Am i missing something? what could the problem be?

EDIT: (I thought the problem was more with the "cron part") Here's twitter.php:

<?
//searches for tweets mentioning "bieber", prints out....

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://search.twitter.com/search.json?q=bieber&rpp=100' );

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

$var = curl_exec($ch);


curl_close($ch);

$obj = json_decode($var, true);

for($i = 0; $i<100; $i++){

echo $obj['results'][$i]['text']."<br/>";
}

echo "<br/>".sizeof($obj);



?>

when i manually refresh twitter.php in the browser i get new results...the goal is to set up an automation of this process so visitors of the site see new (processed) results every minute or so...

EDIT: I actually eventually want to process the search results every minute BEFORE displaying them every minute...how do i pass new values to the $var variable in twitter.php every minute

Answer 1

A cronjob does not affect the browser. In order to refresh the page you could refresh the page automatically with HTML

<META HTTP-EQUIV="refresh" CONTENT="60">

or use javascript

function reloadPage(){
    window.location.reload();
}

setTimeout ( reloadPage, 60000);
