If an array is not NULL

[etrader]

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);

Have you tried doing if empty($array)? 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 }....

You mean

 if (!empty($test_array)) { echo "nothing to display";
} else { running the main code}

 if (!empty($test_array))

worked   THANKS
