Array Processing

[J Huntley Palmer]

How may I concatenate the index respective questions and answers into
one string per index using ONE foreach loop? I do not want to use
numerical indexes just the named ones as below.

In other words, in one foreach loop, if possible, I want to have the
results as question0+answe r0 and question1+answe r1 in 2 separate
strings entered into an array.

Thanks much.

Array
(
[0] => Array
(
[0] => question0
[1] => question1
)

[QUEST] => Array
(
[0] => question0
[1] => question1
)

[ANSW] => Array
(
[0] => answer0
[1] => answer1
)

[1] => Array
(
[0] => answer0
[1] => answer1
)

)

Do you mean this:

for ($i = 0; $i < count($arr[0]); $i++) {
$result[] = $arr[0][$i].$arr[1][$i];
}

Actually I wanter to use the named indexes such as [QUEST] AND [ANSW]
not the numerical ones.

Array
(
[0] => Array
(
[0] => question0
[1] => question1
)

[QUEST] => Array
(
[0] => question0
[1] => question1
)

[ANSW] => Array
(
[0] => answer0
[1] => answer1
)

[1] => Array
(
[0] => answer0
[1] => answer1
)

)
Thanks

This will also create an out of bounds error since there are named
indexes mixed in.

$stuff = array("QUEST" => array(0 => "question0" , 1 => "question1" ),
"ANSW" => array(0 => "answer0", 1 => "answer1")) ;


$strings = null;
foreach ($stuff["QUEST"] as $key => $value)
{
$strings[$key] = $value . $stuff["ANSW"][$key];
}

How do you want to establish the relationship between the questions and
answers? With your example array, only the following would make sence:

$results = array(
$array['QUEST'][0] . $array['ANSWER'][0],
$array['QUEST'][1] . $array['ANSWER'][1]
);
