PHP Translator, replacement for google translator api?.


I struggled to get the language translator for my php project and found Google API is not WORKING FOR ME, I dont know it works for others. While surfed i got google closed its Free Translator API, and microsoft is providing its API with limited character free subscription.

The code providing by them comes in SOAP, HTTP and Javascript and yes it supported my PHP. Even they are providing exact PHP class files that helped me a lot. You can register your Keys with them, use this link for to Sign up for the Microsoft Translator API "https://datamarket.azure.com/dataset/1899a118-d202-492c-aa16-ba21c33c06cb". They have listed all the subscription plans ranges from free to $6000/ month.

I think this link will also helpful http://www.microsofttranslator.com/dev/. After creating your Keys register with Datamarket and your translator will work good. I have used HTTP >> Translate Method "http://msdn.microsoft.com/en-us/library/ff512421.aspx" and there you can see the PHP class files, and it is very handy......


Happy coding

How to get the meta title, description and keywords using PHP



function getUrlData($url)
{
    $result = false;
   
    $contents = getUrlContents($url);

    if (isset($contents) && is_string($contents))
    {
        $title = null;
        $metaTags = null;
       
        preg_match('/<***title***>([^***>]*)<***\/title***>/si', $contents, $match );

        if (isset($match) && is_array($match) && count($match) > 0)
        {
            $title = strip_tags($match[1]);
        }

How to Resize or Scale your image using CSS

There are many best ways to scale the images for your site. We can use the php resize codes or Jquery resize scripts and others, and one of the best way is to scale the images through CSS. For a demo please check the below code



<*****style type="text/css">
.center-cropped  {
    width: 310px;
    height: 168px;
    background-position: 50% 11%;
    background-size: cover;
 }

<*****div class="center-cropped" style="background-image: url('http://elbadil.com/sites/default/files/styles/428xauto_node_image_2/public/13/08/32/0_73.jpg?itok%3Dk9uRSMGi');">
<******/div>


Note: remove ******


In the above code background-size acts as the center point, I just need a whole cover section, but we can use contain or auto or anything as per your needs.

Check the background-position too. I made as 50: 11 Percentage ratio. You can set the height and width and by this there wont be any stretch in the image. But the whole concept will make the load time bit high when compared to resizing :)




Code to make other site image to get stored in your wordpress database as well as making other site images to your wordpress post featured image


$upload_dir = wp_upload_dir();
$image_data = file_get_contents("Image URL for other site");
$filename = basename($image_url);
if(wp_mkdir_p($upload_dir['path']))
$file = $upload_dir['path'] . '/' . $filename;
else
$file = $upload_dir['basedir'] . '/' . $filename;
file_put_contents($file, $image_data);

$wp_filetype = wp_check_filetype($filename, null );
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name($filename),
'post_content' => '',
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
wp_update_attachment_metadata( $attach_id, $attach_data );
set_post_thumbnail( $post_id , $attach_id );


wp_update_attachment_metadata will make the image to get stored in your database

set_post_thumbnail will make the image to get featured for the post

$post_id - will be ID of your post, for example if you just want to make your post id 5 to get featured image then just replace the variable  $post_id with 5





substr in php is not removing characters?


I had a similar problem before and rectified using mb_substr, for demo please check the below code

$then_truncate_the_value=mb_substr($remove_html_first , 0, 123);

How to scrap the titles of a Wordpress site using CURL php?


$curl1 = curl_init();
curl_setopt($curl1, CURLOPT_URL, 'Your URL');
curl_setopt($curl1, CURLOPT_HEADER, false); 
curl_setopt($curl1, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl1, CURLOPT_FOLLOWLOCATION,true);
curl_setopt($curl1, CURLOPT_ENCODING,"");
curl_setopt($curl1, CURLOPT_USERAGENT, "spider");
curl_setopt($curl1, CURLOPT_AUTOREFERER,true);
$result1 = curl_exec($curl1); curl_close($curl1); 


## get the title
preg_match_all('your h1 tag with calss', $result1, $matches1, PREG_OFFSET_CAPTURE);
preg_match('/your anchor tag/', $matches1[0][0][0], $set1);
$my_title=$set1[2];



1) Initialize the CURL
2) Enter the URL
3) Check whether the wordpress site comes with the h1 tag and with the same class i declared here, else use the correct one
4) I dont want the link tag so i removed the <--a---> tag, and finally we will have the result

How to get images for a URL through php?

We can use many concepts for this eithe we can use DOM or CURL or anything. Lets see a simple example on how to use DOM concept





$doc = new DOMDocument();
$doc->loadHTML('Your URL');
$imageTags = $doc->getElementsByTagName('img');

foreach($imageTags as $tag) {
$img_src= $tag->getAttribute('src');
}





By this we can get all the image tag in the particular URL, you can write separate scripts for Image types too.
