Question

PHP Convert String to Integer?

Asked by: jrram

Can someone tell me what is the PHP equivalent of the ASP's CInt() function?

I am trying to convert this piece of code to PHP

for k=1 to 4
   if CInt(userChoice) = k Then choiceChecked = "checked"
next

This is what I have so far:

for ($k=1; $k<5;$k++)
   if (CInt($userChoice) == $k) $choiceChecked = "checked";

I'm just unsure of the conversion function.  And could you also point me to a list of the PHP string conversion functions.

=== matches both value and data type
== matches only value.

-r-

Alternatively you can use the intval() and floatval() functions.

Thank Roonan,

I'm trying to put all the asp to php tips together in this question, but i'm not getting any results back.  Take a look and help if you can.  I can break it up into multiple parts if 500pts isn't enough.
