looping two arrays

[stefano.troiani]

Hi,

i have two arrays and I would like to loop both of them one inside the
other.
The first one comes from a readdir and present an array with the
document's names, the second one is an array with the names i want to
appear for that documents as a link.
My need is to sort both of them so that i got something like this:
<a href="first element of array 1" first element of array 2</a>
<a href="second element of array 1" second element of array 2</a>
..........................................

but i don't know how to do it.

Thanks for any help,

stefano

$array1 = array('first', 'second');
$array2 = array('one', 'two');
for ($i=0; $i<count($array1); $i++) {
echo "<a href=\"".$array1[$i]."\" >".$array2[$i]."</a>";
}

Hi Stefano,

That is very straightforward.
I assume the arrays are both the same length.
(if not your setup makes little sense.)

<?
// both arrays are filled by your code
$arrHyperlink = array(.....);
$arrHyperlinkText = array(.....);

for ($i=0;$i<count($arrHyperlink);$i++){
?>
<a href="<?= $arrHyperlink[$i] ?>"><?= $arrHyperlinkText[$i] ?></a>
<?
}
?>

Simple he? Or did I miss someting? (Happens the whole day to me. :P)

foreach( paths_array AS $key =$path ){

// if document in path exists
if( file_exists($path) ){

// if there is a name for this document, set defined name else set name as "no name"
( $names_array[$key] ) ? $name = $names_array[$key] : $name = "no name";

// print link with document path and document name
print "<a href=\"".$path."\">$name</a>";

}

}

No over head of $i, $i < comparison, and $i increment.
foreach is a far too underused language construct. The other
solutions posted are perfectly workable, I just have a strong
preference for foreach when working with arrays.

Indeed, and it works with named keys, also a handy feature..

How exactly are you linking the document names and descriptions?
If link them purelay on the numerical indexes in both arrays, with one to
one relations, try:

$combined = array_map(null,$files,$desciptions);
foreach($combined as $link){
vprintf('<a href="%s">%s</a>',$link);
}
