Escapeshellarg

Escapeshellarg bypass php

Escapeshellarg adds single quotes around a string and quotes/escapes any existing single quotes allowing you to pass a string directly to a shell function and having it be treated as a single safe argument. Escapeshellarg, as its name indicates, is used as passing shell argument (s). For example, you want to list current directory. Description: - escapeshellarg strip non-ascii characters if the LANG environment variable is not set to somthing like LANG=.ISO-8959-1 e.g. LANG=enUS.ISO-8959-1 The job of escapeshellarg is only to escape characters and NOT to remove them!!! The manual say nothing about removing characters!!!

Php Escapeshellcmd

I wrote function, that gets proxy server value from the Internet Explorer (from
registry). It was tested in Windows XP Pro
(Sorry for my English)
<?php
function getProxyFromIE()
{
exec('reg query 'HKEY_CURRENT_USERSoftwareMicrosoft'.
'WindowsCurrentVersionInternet Settings' /v ProxyEnable',
$proxyenable,$proxyenable_status);
exec('reg query 'HKEY_CURRENT_USERSoftwareMicrosoft'.
'WindowsCurrentVersionInternet Settings' /v ProxyServer',
$proxyserver);
if(
$proxyenable_status!=0)
return
false; #Can't access the registry! Very very bad...
else
{
$enabled=substr($proxyenable[4],-1,1);
if(
$enabled0)
return
false;
else
{
$proxy=ereg_replace('^[ t]{1,10}ProxyServertREG_SZ[ t]{1,20}',',
$proxyserver[4]);
if(
ereg('[=;]',$proxy))
{
$proxy=explode(';',$proxy);
foreach(
$proxy as $i => $v)
{
if(
ereg('http',$v))
{
$proxy=str_replace('http=',',$v);
break;
}
}
if(@!
ereg('^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}:'.
'[0-9]{1,5}$',$proxy))
return
false;
else
return
$proxy;
}
else
return
$proxy;
}
}
}
?>
Note, that this function returns FALSE if proxy is disabled in Internet
Explorer. This function returns ONLY HTTP proxy server.
Usage:
<?php
$proxy
=getProxyFromIE();
if(!
$proxy)
echo
'Can't get proxy!';
else
echo
$proxy;
?>
