incrementing array index

[effennel]

I am trying to access the content passed via $_POST in a loop. What I'm trying to get is this:

 $insAmt_1 = $_POST"['1ins1']";
 $insAmt_2 = $_POST"['1ins2']";
 $insAmt_3 = $_POST"['1ins3']";

then

 $insAmt_1 = $_POST"['2ins1']";
 $insAmt_2 = $_POST"['2ins2']";
 $insAmt_3 = $_POST"['2ins3']";

etc.

What I tried and get parse error with is:

for ($i = 1; $i <= 8; $i++) {
 $insAmt_1 = $_POST"['".$i."ins1']";
 $insAmt_2 = $_POST"['".$i."ins2']";
 $insAmt_3 = $_POST"['".$i."ins3']";
 ...
}

Any suggestions?

Try this:

for ($i = 1; $i <= 8; $i++) {
$insAmt[$i] = $_POST[$i.'ins1'];

}

Sorry, misread your code:

for ($i = 1; $i <= 8; $i++) {
 $insAmt_[$i] = $_POST['1ins'.$i];
 
}

To get the 2ins results either do another loop:

for ($i = 1; $i <= 8; $i++) {
 $insAmt_[$i] = $_POST['2ins'.$i];
 
}

Or put a loop around your first loop:

for($a = 1; $a < 3 ; $a++)
{
  for ($i = 1; $i <= 8; $i++) {
   $insAmt_[$i] = $_POST[$a.'ins'.$i];
 
   }
}

Not sure why you'd want to set and then change the variables for though.

OK.

Looks good. Thanks for your help Dweezel!

Is there anyways that the variable

$insAmt_[$i]

be available as
$insAmt_1
$insAmt_2
$insAmt_2
etc..

outside the loop?

 

[Dweezel]

The code that I posted puts all of the results into an array called '$instAmt_'. So if you wanted to access the variables you could use $instAmt_[0], $instAmt_[1], $instAmt_[2] etc.
