php - Get Meta-Title, Description & Images. -

I have a text box that allows users to post URLs 

  File_get_contents_curl ($ url);   
  $ image_regex = '/ & lt; img [^ & gt;] * ' 'Src = [\ "| \'] (. *) [\" | \ '] / UI';   
 This displays all the images in the URL, I would like to show only one image tag of OG: This URL contains the image.   
 
 
 You can get the first match with this code.
