You can use shell functions to execute php.

exec("php-cgi /path/to/script.php >/dev/null 2>&1");
exec("php /path/to/script.php >/dev/null 2>&1");


Or you can use wget and run it in background mode to run simultaneous script.

exec("wget -bq -o /dev/null http://www.example.com/script1.php");
exec("wget -bq -o /dev/null http://www.example.com/script2.php");


Or you can use cURL to execute simultaneously.

<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://www.example.com/script1.php");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_URL, "http://www.example.com/script2.php");
curl_setopt($ch2, CURLOPT_HEADER, 0);

//create the multiple cURL handle
$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$running=null;
//execute the handles
do {
curl_multi_exec($mh,$running);
} while ($running > 0);

//close the handles
curl_multi_remove_handle($ch1);
curl_multi_remove_handle($ch2);
curl_multi_close($mh);

?>

Okay it looks like you are on shared host or restricted from having extra processes.
Try this:

exec("wget -q http://www.example.com/script1.php >/dev/null 2>&1");

Hi Kaizoku


<?
error_reporting(0);
require_once "auth/config.php";
$link = mysql_connect($hostname, $username,$password);
if($link)
{
$dbcon = mysql_select_db($dbname,$link);
}
$str= "select * from thread where status like 'free'";
$res=mysql_query($str,$link);
while($row=mysql_fetch_array($res,MYSQL_ASSOC))
{
$tnames[]=$row['tname'];
}
$len=sizeof($tnames);
$str1= "select * from urls where status like 'TBC' limit 0,$len";
$res1=mysql_query($str1,$link);
while($row1=mysql_fetch_array($res1,MYSQL_ASSOC))
{
$url[]=$row1['url'];
}
for($i=0;$i<$len;$i++)
{
$query="update thread,urls set thread.status='busy', urls.status='busy' where tname='$tnames[$i]' and url='$url[$i]'";
$result=mysql_query($query,$link);
exec("wget -bq -o /dev/null http://localhost/sitemapprototype/crawl.php");
}

Even after using above command, it is not working.
In the above code I am executing crawl.php and in crawl.php i want to update some data into the database.

[Kaizoku]

That is strange, the code I gave worked on my server. What OS/Distro are you using? Are you using dedicated or shared hosting?
Also turn error_reporting to E_ALL so you will see errors and debug.

Hi Kaizoku

I am using windows xp os and the file which i executed kept in my local machine

[Kaizoku]

Do you have wget installed on your local box?

[kalaid]

I don't know whether wget is installed in my local machine. If I want to install what I have to do

[shallowink]

Get wget for win32 here:
http://www.christopherlewis.com/WGet/WGetFiles.htm
or here:
http://xoomer.alice.it/hherold/
Version 1.10.2 is on both sites, though the first looks like it was updated recently.
Make sure to put it somewhere in your path or call it explicitly.

[Kaizoku]

Because windows can't execute by just calling wget. It doesn't have the feature like /usr/bin in linux I think.
You have to execute wget using the absolute path.

exec("C:/path/to/wget.exe -q http://www.example.com/script1.php");

[shallowink]

I don't know anything about that, could test it though. If i wanted multi process headaches, I'd just use perl.
Thought if he used wget it would have to be somewhere in the webserver path.

Hi Kaizoku
I have uploaded my files into server and tried to execute with both exec() commands

//exec("wget -bq -o /dev/null http://mycollege.in/crawl.php");
exec("http://mycollege.in/crawl.php >/dev/null 2>&1");


The file crawl.php is not executed, but when i execute the file crawl.php separately then it is executed.
Our's is LINUX Shared hosting
Please help me solve this issue

[Kaizoku]

Dude, you just said you were using windows, now it's linux...

[kalaid]

In am writing coding for my project in my windows machine and after completing i want to upload into our site, which is linux shared hosting site.
Now it is working in windows with this function

exec("C:/path/to/wget.exe -q http://www.example.com/script1.php");

But when i upload and call the file with this either of the function

exec("wget -bq -o /dev/null http://mycollege.in/crawl.php");
exec("http://mycollege.in/crawl.php >/dev/null 2>&1");
It is not working.I want to know whether my server is not supporting wget or i have to use any absolute path for wget as in windows

[Kaizoku]

exec("whereis wget", $output);
print_r($output);

Report back the results.

Hi Kaizoku
I got the result as
Array ( [0] => wget: /usr/bin/wget /usr/share/man/man1/wget.1.gz )

Whether i have to provide this path in exec()

[Kaizoku]

I think your shared hosts restricts you to extra processes.
So try this
exec("wget -q http://mycollege.in/crawl.php");
exec("/usr/bin/wget -q http://mycollege.in/crawl.php");

If all fails, the admin probably restricts the usage of wget for normal users.

Hi
Also I want to pass the arguments along with the file inside exec() function.
I tried like this in windows
exec("C:/path/wget.exe -q http://localhost/sitemapprototype/crawl.php?thread=$tnames[0]&url=$url[0]");
The arguments are not passed

[Kaizoku]

You need to wrap it around apostrophes. Arrays need to be wrapped around curly braces as well.

exec("C:/path/wget.exe -q 'http://localhost/sitemapprototype/crawl.php?thread={$tnames[0]}&url={$url[0]}'");

[kalaid]

Hi
I tried this

exec("wget -q http://mycollege.in/crawl.php");
exec("/usr/bin/wget -q http://mycollege.in/crawl.php");

But it fails, So I have to change the access mode of wget.

[kalaid]

I tried with

exec("C:/path/wget.exe -q 'http://localhost/sitemapprototype/crawl.php?thread={$tnames[0]}&url={$url[0]}'");


but the values are not passed to crawl.php file

[Kaizoku]

hmmm try this:

$link = "http://localhost/sitemapprototype/".rawurlencode("crawl.php?thread={$tnames[0]}&url={$url[0]}");
exec("C:/path/wget.exe -q '{$link}'");

[kalaid]

I tried still it fails
Also I tried passing ordinary variables rather than array variable even though it fails to execute.

[Kaizoku]

Okay I give up...

[kalaid]

ok thanks a lot for your help

[Kaizoku]

Something strange with windows wget, it works perfectly fine with linux wget.

[shallowink]

hey kalaid,
you could try to use wget's file option. write your string to a file and then call wget with this
exec("C:/path/wget.exe -q -i filename.txt");

[kalaid]

Hi
The issue here is when i provide
$link ="http://localhost/sitemapprototype/crawl.php?uurl={$urll}&thread={$nam}";
The argument after '&' is not passed. If I provide like this
$link1 ="http://localhost/sitemapprototype/crawl.php?uurl={$urll}thread={$nam}";
The value for uurl and thread is passed along the file but i cannot get the values for uurl and thread seperately. The thread variable and the value is combined along with the uurl as there is no '&' symbol
What to do in such case
