Join Kevin Skoglund for an in-depth discussion in this video Foreach loops, part of PHP Essential Training.
- [Instructor] Foreach loops are a little different…from the previous two types of loops.…Foreach loops are going to take an array…and then loop through each item of the array…until it gets to the end.…If you think back, while loops and for loops…know whether to quit or to keep looping…by testing if a condition has been met.…Foreach loops on the other hand are going to know…whether to quit by whether are items left…in the array to loop over.…The end of the array is what ends the looping.…It's really just two approaches to looping.…Let's use a real world scenario for a second.…Imagine that I have a classroom with 20 kids in it…and I have to put name tags on all of them.…
Now I could just go around the room…and I could put a name tag on each kid…and keep track of the numbers as I went,…and knowing that there are 20 kids,…when I had gotten to the number 20, I'd know I was done.…Or since I know that I have a finite set,…I could just line them all up, start at the beginning…and move down the line,…and when I got to the end of the line…
