ForEach Loop Video Lecture | PHP for beginners - Software Development

Oh YouTube welcome to tutorial number 15
in the PHP programming series and in
this video we are going to cover the for
each loop so the for each loop will
allow us to loop through variables so
you loop through arrays and take out all
the values from that array and do
whatever you want with them so let's
just start our PHP closing starting and
closing tags and say this as for dot PHP
and the first thing we need to do and
you should know how to do this is
declare an array now this array again is
going to call names I'm going to put the
values of names as an array let me Chris
Tom and Bob and these that's simply just
create an array the name is crystal and
Bob you know we just print our this
array and that will just give us the
value of each of each of the parts of
the array so for the PHP you know we've
got Chris Tom and Bob so what we're
going to do now is we're going to create
a for each loop on this for each loop
we'll look through each value of this
array and then we can do something with
each of those values by setting the
array to a variable so what I'm going to
do is do for each and then we'll have
some brackets and curly braces right
here for when we put our code and the
arguments in for each is we're going to
say for each and then here is going to
be the variable so the array name and
that is names and then we put us and now
we need to declare a name of the
variable that we're going to use in the
code so I'm just going to say person so
what we've done here is every time this
this M loops it's going to look at the
names array and it's going to declare a
variable of the current value so either
Chris timer Bob M as the variable person
so we can now use that we can say echo
the name is and then we can cut cut
innate a person we can use person as the
name of the person and save that and
that should loop through every one of
the people so if
go over this again it's saying for each
part of the names array we are going to
use the variable person to represent the
current array value so 0 then 1 then 2
so if we will load this it says the name
is Chris Tom and Bob
so we've looped through that array using
the for each loop so that's pretty much
all the 42 loop is it can it will loop
through arrays and you might find this
useful useful a lot of times say if
you're passing something out and then
you need to loop through each part of
that array that you've passed it into so
