[PHP] System('wget') problem


Question

I'm trying to download a file through php using wget. I have the wget exe in system32 and I can use it successfully over the command line but when I try to use it through php I get a 'wget' not found error as shown below.

Here's the code:

<?php 
	system('wget http://site.com/stuff.sql -O data/tmp.sql');
?>

I'm very new to php so if it's something simple don't hurt me :p

Am using Windows 7, PHP 5.3 and also IIS though I haven't show it above.

Thanks!

I'm not using apache however if I use the code:

<?php

	  echo '<pre>';

	  system('cmd /c "dir"', $retval);

	  echo '
	  </pre>
	  <hr />Return value: ' . $retval;

?>

It shows the current directory list on the webpage and works fine =/

I will look through the php.ini file to see where I can declare wget.

<?php
if(false === file_exists('wget.exe'))
{
	printf(
		"I cannot find wget.exe, the current working directory is '%s'",
		getcwd()
	);
}
?>

Explorer has global scope, so there can be called regardless of the CWD.

Check your CWD using getCWD().

Ah thanks SilverBullet - I've just found that by copying the exe to the root of the C: drive it seems to all work okay.

So now I'm just wondering how do I make it so I can access the wget when it is stored in the System32 directory?

edit: I can also access print the output of the command 'Shutdown.exe -?' which is also only in System32 whereas 'wget' just won't happen :(

Certain commands such as explorer, tasman, cmd, shutdown etc are accessible without specifying a path (as SilverBulletUK said). However wget isn't installed by default on Windows computers (I presume you've found a Linux port on the internet somewhere) so you need to specify the full path to the executable. For example instead of just doing system("wget ...."); run system("C:\WINDOWS\System32\wget.exe ....");

if you just want to get a remote file and save it, why not use file_get_contents and file_put_contents?

I didn't know about them, as I said I'm new to php so I'll see what I can find out about them.

I did try that however it still could not be found, I have no idea why but it just wouldn't happen.

system('C:\Windows\System32\wget.exe http://site.com/stuff.sql -O data/tmp.sql');

Also tried with forward slashes but no luck.

In the end I just copied the binary to the directory php was installed in (c:\program files x86\PHP) and it seems to work without the file path.

However after all that, a new problem came up with deleting the tmp.sql file, can you please look at this code and tell me what's wrong? The folder in the error mentioned below has been given full permissions for IIS_IUSRS.

	if (file_exists('data/tmp.sql')) {
		unlink('data/tmp.sql');
	}

PHP Warning: unlink(data/tmp.sql) [<a href='function.unlink'>function.unlink</a>]: Permission denied in C:\inetpub\wwwroot\Test\Update.php on line 40

Thank you!

    • I think it's bloody great, old chap!
    • Not the deal that 2nd hand purchasers tend to look for - no.  It's cheaper than the sum of it's parts new - yes.  But people looking for 2nd hand, pre-built computers are rarely looking for what you are selling. Don't misunderstand; as an informed enthusiast I like that computer, and as an informed enthusiast I am often asked "My son wants a gaming PC and here's my budget" - in which case, as an informed enthusiast I would totally point them in this sort of direction.  But I am not the mass market, hence you may well have to wait longer for a sale. If you're looking for speed - then breaking it into parts is likely to pay off better on that front, as there will be more people who suit that market and their likelihood of buying 2nd hand is more fruitful.  But - chore!
    • What is the purpose of this article? You didn't even mention that CPU is powering it, so we don't know what GPU/iGPU it has. We don't know if the memory is on chip, on the motherboard, is expandable or replaceable. And that's only the internals. Display type, resolution, brightest you didn't even mention the DPI. Without one or more if these capabilities no one who reads these strung together words will know if they should or shouldn't buy it. The only HINT is from the sticker on the photo of the laptop. Q: what do you get for wasting people's time? Their must be some value or you wouldn't have wasted your time either.
    • That is some storage. I have an old F4-210 and it works well for what it is, just a shame Terramaster will not update the software for it.
