can you foreach() two arrays at once ?

Hello,
So, I was wondering how to do this:

foreach($foo as $k=>$v AND $bar as $k2=>$v2){
echo '<TR><TD>$k</TD><TD>$v</TD><TD>$k2</TD><TD>$v2</TD></TR>;
}

Thanks,

No.

However, you can use "each" to do the same thing, i.e.

reset $array1;
reset $array2;

for ((list($key1, $val1) = each($array1)) &&
(list($key2, $val2) = each($array2)) {
// $key1 and val1 contain the key and value for an element in $array1
// $key2 and val2 contain the key and value for an element in $array2
// Do your stuff here
}

It will stop as soon as you run out of elements in either array.

Ah, cool, I saw similar on the php.net. Is there a way to do it so that it will
go thru all of both, even if one runs out?

if (count ($arr1) count($arr2)) {
$len = count($arr1);
}
else {
$len = count($arr2);
}

Now

foreach($i=0; $i < $len; $i++) {

list($key1, $val1) = @each($arr1);
list($key2, $val2) = @each($arr2);
}

What about this?
I have not checked this.

There I used "foreach" instead of "for".

What do you want to do with the array which runs out? And what do you
want to do with the array with items left?

I figured the var that ran out would just be empty while the other var is still
listing, eaching, etc. It might be handy to be able to specify a default value
instead of empty, like &nbsp for the table exapmle above. Looks like I could
just stick a little if() in Satya's code.

Well, neither of these are working, Jerry's (both scripts) have a syntax error,
(missing ; and I cant figure where it wants it) and Satya's outputs:
0 Array 0 0
1 Array 1 1
2 Array 2 2
3 Array 3 3
4 4

Nope, both if statements are in the loop. Each time through it will
process $val1 then $val2.

Your suggestion of array_pad() is also good, unless the arrays are large.

Isnt there supposed to be 3 expressions in a FOR? I tried with semicolons here

Sorry - it should be a 'while' loop, not a 'for' loop.

What do you want to do with the array which runs out? And what do
you want to do with the array with items left?
I figured the var that ran out would just be empty while the other
var is still
listing, eaching, etc. It might be handy to be able to specify a
default value
instead of empty, like &nbsp for the table exapmle above. Looks like
I could
just stick a little if() in Satya's code.
OK, then try this:

reset $array1;
reset $array2;

for (($val1 = each($array1)) || ($val2 = each($array2)) {
if ($val1) { // false if at the end
// $val1['key'] contains the key
// $val1['value'] contains the value
echo $val1['key'] . '=>' $val1['value'];
}
else
echo '&nbsp;';
if ($val2) { // false if at the end
// $val2['key'] contains the key
// $val2['value'] contains the value
echo $val2['key'] . '=>' $val2['value'];
}
else
echo '&nbsp;';
}

Hmmz, haven't tried it, but won't the second list argument only be run
when the first fails, so in essence 2 foreach loops after one another?

Nope, both if statements are in the loop. Each time through it will
process $val1 then $val2.

<?php
$a = $b = array();
for($i = 1;$i<5;$i++){
$a[] = 'a'.$i;
$b[] = 'b'.$i;
}
while(($val1 = each($a)) || ($val2 = each($b))){
if (isset($val1) && $val1) { // false if at the end
// $val1['key'] contains the key
// $val1['value'] contains the value
var_dump($val1);
}
else
echo 'a not set';
if (isset($val2) && $val2) { // false if at the end
// $val2['key'] contains the key
// $val2['value'] contains the value
var_dump($val2);
}
else
echo 'b not set';
}
?>
Output:
array(4) {
[1]=>
string(2) "a1"
["value"]=>
string(2) "a1"
[0]=>
int(0)
["key"]=>
int(0)
}
b not setarray(4) {
[1]=>
string(2) "a2"
["value"]=>
string(2) "a2"
[0]=>
int(1)
["key"]=>
int(1)
}
b not setarray(4) {
[1]=>
string(2) "a3"
["value"]=>
string(2) "a3"
[0]=>
int(2)
["key"]=>
int(2)
}
b not setarray(4) {
[1]=>
string(2) "a4"
["value"]=>
string(2) "a4"
[0]=>
int(3)
["key"]=>
int(3)
}
b not seta not setarray(4) {
[1]=>
string(2) "b1"
["value"]=>
string(2) "b1"
[0]=>
int(0)
["key"]=>
int(0)
}
a not setarray(4) {
[1]=>
string(2) "b2"
["value"]=>
string(2) "b2"
[0]=>
int(1)
["key"]=>
int(1)
}
a not setarray(4) {
[1]=>
string(2) "b3"
["value"]=>
string(2) "b3"
[0]=>
int(2)
["key"]=>
int(2)
}
a not setarray(4) {
[1]=>
string(2) "b4"
["value"]=>
string(2) "b4"
[0]=>
int(3)
["key"]=>
int(3)
}

So, the original argument still stands: the second expression will not be
evaluated in this conditional as long as the first will return true.

Darn, you're right - I've been in vbscript too much recently (don't ask!
:-)). And it evaluates the entire expression.

Better would be:

for ($val1 = each($a), $val2 = each($b); $val1 || $val2;
$val1 = each($a), $val2 = each($b))

Does that make you happy? :-)

Sorry - that should be:

for (($val1 = each($array1)) || ($val2 = each($array2))) {

Missed an extra paren at the end.

Thanks again for the help, however, I still get:
Parse error: syntax error, unexpected ')', expecting ';' in
/web/sites/asdf/asdf.com/_impexp/test.php on line 55

Isnt there supposed to be 3 expressions in a FOR? I tried with
semicolons here
and there, but couldnt get it.
current code:
for (($val1 = each($users)) || ($val2 = each($newusers))) {
if ($val1) { // false if at the end
// $val1['key'] contains the key
// $val1['value'] contains the value
echo $val1['key'] . '=>' $val1['value'];

try

$keys = array_map(null, array_keys($a), array_keys($b));

if you don't need keys, this can be simplified to

foreach(array_map(null, $a, $b) as $v) {
list($v1, $v2) = $v;
echo "$v1 - $v2 \n";
}

More like that. $a and $b are db results (arrays). Each element has its own
array of feild=>value.

I tried a couple things, nesting those scripts inside each other, but to no
avail.

Same as before, go through each array, for each element, list all the
key=>values for both:
$a[0][key]-val -- $b[0][key]-val
// etc for all key-vals in $a[0] and $b[0]
$a[1][key]-val -- $b[1][key]-val
//etc

OK, so just create an inner loop similar to the existing one, which goes
through each of the elements in the arrays.
