limit number of characters to 200 / array

[randall]

Hey folks! Happy what ever you are celebrating

 

I am trying to limit the number of characters to 200 that this array echos. I have tried a few things... I have tried using "substr($arr_tem, 0, 200)" but obviously it is not working... but I think I am close-ish. Any assistance would be great!

 

###print array###
echo (implode(", ", array_keys($arr_tem)));

 

Thanks!

cant substr the array, but you can substr the outcome of the implode.

 

###print array###

echo substr(implode(", ", array_keys($arr_tem)),0,200);
