PHP Notice: Undefined index: call in /var/www/swvx/timedcdr2.php on line 72

I am getting this error on the following code, and cant figure out why. I think it is looping through each $call twice, but I dont know why. Anyone care to give me a hand proofreading?

PHP Notice: Undefined index: call in /var/www/swvx/timedcdr2.php on line 72

Thanks!

edit- It does work; it just th开发者_如何转开发rows that error once in a while. At least I tihnk it works. I assume that it maybe gets to the last result of the pbx_accountid array and theres no more? I am going to count the number of times it goes, and see if it corresponds.

edit- yes, there are 20 occurences of the error every time it's run, and there are 20 account IDs. How do I force it to stop if there are no more call indexes?

Change this

if($result['calls']['call']) {   //<====LINE 72 ################################

To this

if(isset($result['calls']['call'])) {   //<====LINE 72 ################################

That notice means you're reading a variable which doesn't exist. You're doing so to check if the variable exists. There's a function to check if a variable exists without trying to read it, isset.
