jquery - Get height of image in 2nd LI -

-

In this code to achieve the height of the image contained in the 2nd layer, struggling to get the right jQuery ... any idea ? 

  & lt; Ul class = "example" & gt; & Lt; Li & gt; & Lt; Img src = "example.jpg" width = "500" height = "500" & gt; & Lt; / li & gt; & Lt; Li & gt; & Lt; Img src = "example.jpg" width = "500" height = "500" & gt; & Lt; / li & gt; & Lt; / Ul & gt; Use    
 
 
 or  eq is zero-index based  Therefore it starts with 0  
  $ ('example li: eq (1) img'). Height ();

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.
