Since I used cURL, I tried to deal with different headers, but with no luck at all. I found the solution at MSDN website. The correct string is:

curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Expect:’));

You need to add it to your cURL block. This issue is related to Twitter only; I have no idea why they decided to accept only blank Expect header. Hope it saves you some time.

$string = "Строка";
$string = mb_convert_case($string, MB_CASE_LOWER, "UTF-8");
echo $string;

//output is: строка
?>

You can check reference table for functions, I think you will find more useful functions for you.

// strpos that takes an array of values to match against a string
// note the stupid argument order (to match strpos)
function strpos_arr($haystack, $needle) {
if(!is_array($needle)) $needle = array($needle);
foreach($needle as $what) {
if(($pos = strpos($haystack, $what))!==false) return $pos;
}
return false;
}
?>

This function will be useful if you need to find whether ANY element of array is presented in the source string. Else you have to either modify it, or create another one.

The solution is very simple. The only restriction is that you should have rights to use exec() or system(). Though, I don’t think there is any reason to deal with the paths if you are not allowed to run system applications. Here is the code:


$var=exec ("which unzip");
echo $var;


What does this code do? It catches the output of system which command to a variable. Then you can use this variable for your purposes. Of course, you should verify the value of the variable before using it. You may also need to echo something, if unzip is not installed.

This technology can be applied to any other system binary you need to know the path of. $var=exec (“which sh”); will tell you the location of sh, if you need to run any shell scripts with your PHP script, and so on.


$srcfile="/path/to/db4file";
$id=dba_open($srcfile, 'c', 'db4');
dba_close($id);
?>


The solution is quite simple. If there were no changes made to user data, you should update your time. Yes, you should sync your server time to any time server. I can’t know the reason, but LR should ensure your time is correct before letting you use their API functionality. You can check Ntp Synchronisation setup or sync your time manually. Hope this saves you some time, as this feature is not documented.

I will show it as PHP code:

preg_match(‘/^(http:\/\/|https:\/\/)([^\.\/]+\.)*([a-zA-Z0-9])([a-zA-Z0-9-]*)\.([a-zA-Z]{2,4})(\/.*)?$/i’, $_POST['url']);

It will check whether url suits the pattern. May not be ideal, but it’s working.

<?
set_time_limit(0);
// Here is our search term
$search=”Test search”;
// Let’s prepare it for Google
$slovo=urlencode(trim($search));
// Here comes the Google URL
$google=”http://www.google.com/search?q=”.$slovo.”&num=10″;
// Let’s place all the links into a single file.
$links=fopen(“$slovo.txt”,”a+”);
// Getting the page contents from Google
$content= @file_get_contents($google);
// Simple and dirtty regular expression, that does the job $matches is the result.
preg_match_all(‘/<h3><a href=”([^">]+)/’, $content, $matches);
// Here are our urls: let’s echo them and write to a file
foreach ($matches[1] as $url)
{
echo $url.”\r\n”;
fwrite($links, $url.”\r\n”);
}
fclose($links);

?>

It works at the moment; Google might change the SERP output format, then you will need to change the regexp. The rest is very simple, this script should work on any host, even without cURL support.
