How do you join two php string variables?

[TylerNZ]

Hi, could someone please tell me how I can join two php string variables?! Here's my code:

for ($i=0; $i<$children; $i++) 
{
$child_name.$i = htmlentities($_POST['child_name$i']);
$child_age.$i = htmlentities($_POST['child_age$i']);
$child_mom.$i = htmlentities($_POST['child_mom$i']);
$child_require.$i = htmlentities($_POST['child_require$i']);
} 

???

THANKS!

What exactly is the trouble from what you have there its correct

However id do this differently
$_POST['child_name$i']

as

$_POST['child_name'.$i]

I don't know what the problem is!! ... I've managed to get around it with:

for ($i=0; $i<$children; $i++)  

	{
			$child_name = "child_name".$i;
			$child_age = "child_age".$i;
			$child_mom = "child_mom".$i;
			$child_require = "child_require".$i;

		$child_name = htmlentities($_POST['child_name'.$i]);
		$child_age = htmlentities($_POST['child_age'.$i]);
		$child_mom = htmlentities($_POST['child_mom'.$i]);
		$child_require = htmlentities($_POST['child_require'.$i]);
}

php will not parse single quotes for variables like this-->>
'child_name$i'

The original code has a concatenation taking place on the left side of the = sign, which doesn't make sense.

Compute on the right. Assign to the left.

So there's no way to make a variable like that ... then assign a value to it in the same line? do you have to double it all up like I did in the end there.

and those single quotes seem to be working??? :rolleyes:

Look up "variable variables" in the PHP manual.

But don't do it. If you are trying to make a collection of like items, use an array.
