New to PHP and in need of help...

[ketarn]

Hi there I'm new to PHP and while the site I am building is coming along nicely I'm stuck.  My problem is, is there someway I can accomplish something like this:

 

<?php

 

  $field1 = 0;

  $field2 = 0;

  $field3 = 0;

  $field4 = 0;

  $field5 = 0;

 

?>

 

With a for loop?

 

for($i=1;$i<=5;$i=$i+1)

 

where the variable $i would replace the numerical portion of the $field variable name?  Again I'm still pretty new to all of this so any help at all would be greatly appreciated.

 

Thanks in advance.

Yea you can buddy

 

<?php

for($i=1;$i<=5;$i++)
{
$field.$i=0;
}

for($i=1;$i<=5;$i++)
{
echo $field.$i;
echo "<br>";
}

?>

This is very basic, and can be achieved using arrays. I would recommend reading about them. However, here is an example:

 

<?php
for ($i = 1; $i <= 5; $i++)
{
   $field[$i] = 0;
}
?>

 

However, if you insist on not using arrays, it is also achievable with variable variables (though I would not recommend this approach):

 

<?php
for ($i = 1; $i <= 5; $i++)
{
    $var = "field$i";
    $$var = 0;
}
?>

You can do that using variable-variables.

 

<?php

for($i=1; $i<=5; $i++)
  ${field.$i} = 0;
echo $field1.$field2.$field3.$field4.$field5;
//output= 00000

?>

 

But this method is not recommended. You should use arrays in this case.

 

Orio.
