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.

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.
