for each loop

[BlueM]

Hey guys this is pretty simple i guess but i need some help.

 

I am trying to output both information from the arrays but without doing the loop twice.

 

 

this is my output:

 

applefruit
appleveggie
appletree
carrotfruit
carrotveggie
carrottree
pinefruit
pineveggie
pinetree

 

but I would like to have an output like :

 

applefruit

carrotveggie

pinetree

 

here is my code

<?php
$first="apple,carrot,pine";
$second="fruit,veggie,tree";


$array1=explode(",", $first);
$array2=explode(",", $second);

foreach($array1 as $number1) {

foreach($array2 as $number2) {

echo $number1.$number2."</br>";


}}
?>

Code inside a loop executes once for every time in the loop. Code inside a loop inside a loop executes once for every time in one loop and again for every time in the other loop. 3 fruit * 3 other things = 9 times total.

 

PHP doesn't have a loop you can use for multiple arrays at once, so you have to do it yourself. The job is easier with functions like reset, key, current, and next. (There are other ways too.)

$first = "apple,carrot,pine";
$second = "fruit,veggie,tree";

$array1 = explode(",", $first);
$array2 = explode(",", $second);

reset($array1);
reset($array2);

while (key($array1) !== null && key($array2) !== null) {
	$number1 = current($array1);
	$number2 = current($array2);

	echo $number1, $number2, "<br>";

	next($array1);
	next($array2);
}

or you could combine the two arrays

$array3 = array_combine($array1, $array2);
foreach ($array3 as $k=>$v) echo "$k$v<br>";
