[PHP] String construction help required please

2003-12-01 Thread Dave Carrera 
Hi List,

I need to construct a string to visually show to the user some $_POST vars.

I need to display : $_POST[$var], 

Including the  and the , .

I have tried : \\$_POST[\.$var.\], but that is very wrong.

Could one of you kind list members show me what it should be please ?

Thank you in advance for any help.

Dave C

Doyou mean you want to do the following? :

echo ''.$_POST[$var].',';

Cheers,
Rob.

You have a couple of options... just pick the one that suits you...

?
echo \{$_POST[$var]},\;
echo ''.$_POST[$var].',';
?

var should not have a $ in front of it, should it? 

echo \{$_POST['var']},\;
echo ''.$_POST['var'].',';

That all depends. Consider the following:

Assume:
input type='text' name='something' value='foo'
to be posted to the script

print '$_POST[$var],'; // prints (literally): $_POST[$var],
print ''.$_POST['something'].,; // prints: foo,
print ''.$_POST[$var].,; // Issues a 'notice: undefined index..' and
prints: ,

$var = 'something';
print ''.$_POST[$var].,; // prints: foo,

Pick your flavor.
