etrader Posted January 19, 2011 Share Posted January 19, 2011 I have an array which can be empty; in this case, I get error. I want to skip when the array is empty. When calling the array from file, I use the following code if (file_exists($array_file)) { "the doing code" } else { echo "File does not exist"; } How I should use this If Else condition when array comes from a string like $test_array = explode(', ', $examplestring, -1); Quote Link to comment Share on other sites More sharing options...

It would work with your exploded variable too, since explode returns an ARRAY of strings. So empty($array), or if (!empty($test_array)) { do whatever }....

etrader Posted January 19, 2011 Author Share Posted January 19, 2011 You mean if (!empty($test_array)) { echo "nothing to display"; } else { running the main code} Quote Link to comment Share on other sites More sharing options...
