Array Simply question

[Angela]

[code]<?=$wcr[$i['country']]?>[/code]
This code prints country name from Array
[code]$wcr=array(
'All countries',
'Albania',
.... etc ...
...'
);[/code]
Need to print only value from Array (0, 1, etc.) not country name. How i must change code?
Thank you in advance.

I'm not totally sure I get what you're asking, but...

[code]
<?
echo array_search($i['country'], $wcr);
?>
[/code]

[Barand]

or do you want


[code]<?=$i['country']?>[/code]

[Angela]

Not works. Thanks anyway.
I need not echo, just how to retreive as Array keys - 0, 1, 2 etc (not their values -Albania, etc).

[Zubaz]

okay then:
[code]
<?=array_search($i['country'], $wcr);?>
[/code]

[code]
foreach ($wcr[$i] as $key=>$value):
    echo $key[$i];
endforeach;
[/code]
perhaps this?

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]foreach ($wcr[$i] as $key=>$value):
echo $key[$i];
endforeach;[/quote]
not works again : Invalid argument supplied for foreach()
[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]<?=$i['country']?> [/quote] - get no results

What i need:
[code]<?=$wcr[$i['country']]?> [/code]- it gets value from array (i.e. Germany)
Need to get ONLY Array key. i.e number for Germany in array $wcr.

Then need no echo, i want to insert this varable into link
[code]<A href="http://someurl.com/search.php?from=0&amp;country=0"><?=$wcr[$i['country']]?></A>[/code]

Now country=0. need to change it, when country will change.

I suppose you have the country name, and you need to find out key location.

Here is one way to do it:

$country = "Germany"; // say you want to find key location for Germany

foreach ($wcr as $key=>$val)
{
if ($val == $country)
return $key;
}

Yes, you are right it so easy, but just courious - NOT WORKS :-( no results

I might be jumping into the middle of things here, but you can't do a return in a foreach loop.

[Angela]

It works when:
[code]<? foreach($wcr as $key=>$value)
{ print_r ($i['country']); }?>[/code]
but need some correcting in code, because prints as key too many copies like this: 77777777777777777777....7
How to change that get without copies?
Maybe someone can help...

[ober]

Why are you printing an entire array repeatedly that doesn't have ANYTHING to do with the foreach loop?

I don't know. ober please tell me what can i do?

[emehrkay]

so you want to print each key in the array? or do you want to print the key that matches a specific country?

to print each key, someone wrote this earlier with the wrong syntax

foreach($wcr as $key => $value){
echo $key."<br />";
}



to mactch simply provide the country

$country = "Albania";

foreach($wcr as $key => $value){
if($value == $country){
echo $key."<br />";
break; //im not too sure if you need it or if it works in this type of loop
}
}
