variables in php

acs888

i have a form which has variable names like

Pname0=somestring;
Pname1=somestring;
....

anyway.....the page which takes the data from this form needs to call these variables so i can do something with them. well.....i cannot figure out how to call them.........meaning how do i add the integers to the variables (in my recieving page) to call the initial POSTED variables?

i know this is incorrect but this is what i am after:

print(" Your Pname is : $(Pname+$count)");

where Pname is a String and $count is an integer, i need to combine them into say... $Pname0 where $Pname is a variable.

thanks, hope this makes sense!

Try using this instead:

$user_pname = "Pname" . $count;
echo "Your Pname is :" . $user_pname;

At least I assume this is what you are trying to do. Let me know if this isn't what you are after though.

You can do it with variable variables:
http://www.phpbuilder.com/manual/language.variables.variable.php

<?php
$Pname0 = 'zzzzz';
$user_pname = "Pname" . 0; 
echo "Your Pname is :" . $$user_pname; 
?>

But it would be better to learn how to use an array on the form.

it seems as though my initial post was a bit unclear, my example was not very accurate, i apologize. my form, when submitted calls pageB.php. in this page, pageB.php, i am going to do something with the variables which were posted. the posted variables are like this:

pname0=Joe Shmo;
pname1=Joe Smith;
pname2=......

and so on.

i have a variable that is posted as well, $Key, which tells me how many pname's there are. so i am going to create a while loop to call each posted variable, however i have no idea how to create a variable name (Pname#) out of other variables.

my loop will look a little bit like this:

$count=0;
while($count<$Key)
{
print("Your name is : $("Pname".$count)");
....more stufff.....
}

is this a bit more clear? i need to make a variable $Pname# where # is an integer which will be incremented. thanks for the help guys!

tomhath your solution worked. at first glance i thought your code did something else, then i realized the double $. thanks guys!

You shouldn't be accessing the variables that way anyway since that depends on globals.

Save yourself a massive headache and do this:

for ($i=0; $i <= $_POST['key']; $i++) {
  echo $_POST['pname'.$i];
}
