A few day ago a needed to compare some cyrillic words and letters with PHP. In the example I take last name and check if the last letter is cyrillic “a”.

function check_female( $last_name = "Иванова" ){

	if(strcmp(mb_substr(($last_name), -1,1,"UTF8"), "а") == 0){
		return 1;
	}else{
		return 0;
	}

}

//IN_ARRAY for multidimensional array			
function in_array_r($needle, $haystack, $strict = false) {
    foreach ($haystack as $item) {
        if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) {
            return true;
        }
    }

    return false;
}	

function currency_convert($amount, $from, $to){
	$result = file_get_contents("https://www.google.com/finance/converter?a=$amount&from=$from&to=$to");
	$result = explode("",$result);
	$result = explode("",$result[1]);  
	$converted_amount = preg_replace("/[^0-9\.]/", null, $result[0]);
	echo $converted_amount;
}

currency_convert(1,'gbp','usd');

Ajax contact form template

function randomWords($paragraph){ //get one from the words in {}
		preg_match_all('/{(.*?)}/s', $paragraph, $matches);
		foreach($matches[1] as $variations){
			$variations_array = explode('|',$variations);
			$paragraph = str_ireplace('{'.$variations.'}',$variations_array[array_rand($variations_array)],$paragraph);
		}
		return $paragraph;
	}

For example {traces | trails | spots}. Will return one of the words in brackets.

Here I prepared some excel file with initial steps for new instalation of OpenCart. These steps will be edited and more will be added later.

This function will download images from another site , resize them and put suffix (if needed).

function download_resized_jpeg($filename,$width,$height,$suffix){
	$name = explode('/',$filename);
	$newfilename = end($name);

	// Content type
	//header('Content-Type: image/jpeg');

	list($width_orig, $height_orig, $type) = getimagesize($filename);

	$ratio_orig = $width_orig/$height_orig;

	if ($width/$height > $ratio_orig) {
	   $width = $height*$ratio_orig;
	} else {
	   $height = $width/$ratio_orig;
	}

	// Resample
	$image_p = imagecreatetruecolor($width, $height);
	if ($type == 1)
    {
        $image = imagecreatefromgif($filename);
    }
    elseif ($type == 2)
    {
        $image = imagecreatefromjpeg($filename);
    }
    elseif ($type == 3)
    {
        $image = imagecreatefrompng($filename);
    }
    else
    {
        $image = imagecreatefromwbmp($filename);
    }
	
	if($type==1 or $type==3) //this code below should preserve transparency but I couldn't try it out for now...
    {
        imagealphablending($image_p, false);
        imagesavealpha($image_p, true);
        imagecolortransparent($image_p, imagecolorallocatealpha($image_p, 0, 0, 0, 127));
    }
	
	imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

	// Output
	if ($type == 1)
        imagegif ($image_p, "../pictures/$newfilename$suffix".".gif", 100);
    elseif ($type == 2)
        imagejpeg($image_p, "../pictures/$newfilename$suffix".".jpg", 100);
    elseif ($type == 3)
        imagepng ($image_p, "../pictures/$newfilename$suffix".".png", 0);
    else
        imagewbmp ($image_p, "../pictures/$newfilename$suffix".".bmp", 100);
}

If you are doing a ajax call to retrieve data from your own server on a platform which is set to prevent these ajax calls . To bypass “Access-Control-Allow-Origin” you need to allow cross domain access by including this in your server php code.

 header('Access-Control-Allow-Origin: *'); 

OR – for only one domain

 header('Access-Control-Allow-Origin: http//your-domain.com'); 

I hope this will help you gain access to you cross-domain data.
