Question

although i use foreach and while,

i was wondering if using the for(i=0;i<varlength;i++) will have some difference, how does php process for() and foreach() differently?

Answer 1

For loops are a bit faster, but consider the following:

$bar = array("cow"=>"moo", "cat"=>"meaw", "dog"=>"barf");
foreach($bar as $key => $value){
 echo "The ".$key." goes ".$value.".<br>";
}

• With foreach you have easier access the the values as well as the key values. This becomes easier and more apparent with associative array operations.
• foreach is a bit easier to read and maintain.
