how do I make it a string

Anon

When I used to develope in ASP I had this really nice function that I could pass just about anything to and it would always come back to me as a string with all the escape characters converted to HTML safe. I am tryingo tdo something similar with PHP but I am having a hell of a time with forcing something to be a string because there is no variable declaration.

Here is my old ASP function:
function undefRemove(t)
{
t = new String(Request(t));
t = t.replace(/\\"/g, \""\");
t = t.replace(/>/g, \">\");
t = t.replace(/</g, \"<\");
t = t.replace(/\\'/g, \"`\");
if(t == \"undefined\") t= null;
return t;
}

Can anyone help me to make it a PHP function? Probably something like this but not exactly...
function undefRemove($t)
{
$t = new String(Request($t));
$t = eregi(\"\\"\", \""\");
$t = eregi(\"\>\", \">\");
$t = eregi(\"\<\", \"<\");
$t = eregi(\"\\'\", \"`\");
if($t == \"undefined\") {$t= null;}
return $t;
}

I'm not sure I got what you're triing to do, but check addSlashes(), addCSlashes, htmlentities() (all under "String Functions") and urlencode() ("URL Functions") in manual. One of them should be what you're looking for.

OK, I understand the htmlentities() function and the urlencode() but I am not quite sure that the addSlashes() will do for me.

What brought this all about is my need to concatinate a string and a variable and so that PHP will see that as another variable from a POST. So I have a root string called $name it then increments $name0, $name1, $name2.... I had thought I could through it in a for loop with a variable $i as the counter and then just set $name = $name.$i. But that does not seem to work...

ideas?

${"name".$i} or

${"name$i} or

$varname = "$name$i";
use $$varname

variable variables.

Yup that worked great thanks.

I take it the { lets PHP know that there is a string following?

Not exactly. PHP treats the expression in "${" "}" as variable name (so, yes, it is string, but is interpreted as the name).
