PHP variable like $var['$var']

I'm c开发者_Go百科urrent making a website with a photo album in it. The website in 2 languages, english and dutch. So I made language file like:

$lang['hello'] = 'Hallo'; //Hallo is hello in dutch

With the photo album I'm trying use the same principle like:

$lang['discription_001'] = 'photo of a house';

With showing the images I made a counter, now I want to use the same counter in the dispription like so:

echo $lang['discription_'$counter] 

And $counter being 001 for photo number one. However this does not work, Could someone tell how I could get this to work, or any other method to get what I want.

Thanks in advance, Thomas de Zeeuw

P.S. I'm new in PHP, however I normally pick up things quite fast, so make some explaintion would be appreciated.

You're almost there:

echo $lang['discription_' . $counter]

The . is PHP's concatenation operator, for combining strings.

---

You just forgot the string concatenation operator . to concatenate 'discription_' and the value of $counter:

$lang['discription_'.$counter]

---

You have a typo.

echo $lang['discription_'$counter]

Should be

echo $lang['discription_' . $counter];

---

You could get it to work by simple repairing your code:

echo $lang['discription_'.$counter];

or

echo $lang["discription_{$counter}"];

---

Is $counter a string?? If so your example should work fine if you fix the parse error (You missed the concatenation operator (.).

It would be much better if you showed us actual code from your application.

echo $lang['discription_' . $counter];

---

As you have got answers already you forgot the concatenation operator, but better way in my mind would be to use multidimensional array.

echo $lang['descriptions'][$counter];
