Hi all, I have a wsdl (xml) file that provides course number, name and textbook. I am using foreach ($result as $course) to get courseID so that I can get the courseName and textBook for each course. Some courses have more than one textBook so the course is listed multiple times. For example, if a course has 3 textBooks, it is displayed 3 times, like so: CourseID CourseName TextBook 1101 Biology101 biology textBook title 1 1101 Biology101 biology textBook title 2 1101 Biology101 biology textBook title 3 I would like to list the course once and then check for multiple textBooks and display all textBooks at the same time, as follows: CourseID CourseName TextBook 1101 Biology101 1. biology textBook title 1 2. biology textBook title 2 3. biology textBook title 3 I have put the information into an array which displays like this: Array ( [0] => 1101 , Biology101 , biology textBook title 1 [1] => 1101 , Biology101 , biology textBook title 2 [2] => 1101 , Biology101 , biology textBook title 3 [3] => 1106 , Math106 , math textBook title 1 [4] => 1106 , Math106 , math textBook title 3 ) What is the best way of accomplishing this? Should I use an array to add all the information or try another approach? Thanks for any suggestions.
