I am not able to understand the example of foreach loop and what is the foreach ($name is $name)in it

Answer 1

foreach is used to iterate through an array. consider an example :
$fruits = array('apple','orange','banana');
now we want to get each element of the array fruits. So we can use for each.
foreach($fruits as $fruitname)
{
echo $fruitname;
}
here $fruitname is any arbitrary name for the variable.
Each time the loop iterate, value of the current
element is assigned to $fruitname.
so first iteration $fruit name will be apple and will echo apple and pointer is incremented.
next $fruitname will be orange.
and next banana.

foreach loop is used for array. if we want to get each element of an array then we can foreach loop in php..for example
$color= array('red','green','black');
foreach($color as $value)
{
echo $value;
}
all colors will display on screen. $value is a copy of variable color. you can use any other name its up to u..foreach loop is used for array..when loop execute first time then then value on 0 index is red. pointer then move on second index then the value will get that is green and so on
