Hi

I have this code :

Code: Select all

<?PHP
$a = 'df';

$b_df = 'Woow';

print $b_$a;
?>
How could I get the string : $b_$a ?? it must equal to $b_df

Take a look at http://www.php.net/manual/en/language.v ... riable.php or (even better) use arrays instead.

Code: Select all

$a = 'df';
$b = array('df'=>'Woow');
print $b[$a];

What you need this for, I have no idea. But see http://www.php.net/manual/en/language.v ... riable.php for how to do variable variables.

Code: Select all

<?php
$a = 'bc';
$d_bc = 'Woow';

echo $d_{$a};
?>
Untested, but i should work.

Arrays are the easiest and most sensible option.
