I am writing a sql query creator using some parameters. While doing that ,I came across this problem. In java , Its very easy to detect the last element of an array from inside the for loop by just checking the current array position with the array length.

for(int i=0; i< arr.length;i++){

     boolean isLastElem = i== (arr.length -1) ? true : false;        

}

php has some different fashion. They have non integer indexes to access arrays. So you must iterate over an array using foreach loop. But it becomes very problematic when you need to take some decision (in my case to append or/and parameter while building query).

I am sure there must be some standard way of doing this.

How do you solve this problem normally in php ?
