Type Juggling in PHP

[r_honey]

There are two things I am trying to accompolish with PHP types & arrays. Hope somebody here can help me:

 

1) You can use

$a = integer;

in PHP. That helps you to recapture the purpose of the variable when you  or others visit the code later.

I am trying to initialize the above variable, i.e. something like

$a = integer =5 ;

or

$a = integer(5);

All these give parse errors. Is it possible to accompolish what I am trying???

 

2) You can return an array for indexing with both associative & otherwise, with mysql functions. I need to provide a similar functionality in my library, where users can enter elements in an array using keys, but retrieve it later using numeric indexes in the order in which they were entered.

So, is this feasible???

1)

<?php
   $a = 5 //integer
   $b = 5.01 //float

   if (is_numeric($a)) echo '$a is numeric<br />';
   if (is_numeric($b)) echo '$b is numeric<br />';

   if (is_int($a)) echo '$a is an integer<br />';
   if (is_int($a)) echo '$b is an integer';
?>

 

2) You mean something, like an array?

I believe you did not get my point. Ok then, tell me if

 

$a = integer;

 

is valid or not in PHP???

 

And ues, I mean like an array...

This is the only way ok

 

post ansaw has already been posted

<?php
   $a = 5 //integer
   $b = 5.01 //float

   if (is_numeric($a)) echo '$a is numeric<br />';
   if (is_numeric($b)) echo '$b is numeric<br />';

   if (is_int($a)) echo '$a is an integer<br />';
   if (is_int($a)) echo '$b is an integer';
?>

 

 

please tell us what ur tying to do ok.

You can use typecasting in php. eg;

 

<?php

  $a = (int) 5;

?>

Looks like type casting or type checking is the only solution.

Thanx guys...

PHP is a dynamically typed language. Its a feature. If you really need this functionality, your probably using the wrong language.
