Help with confusing syntax

[mclamais]

I have list of say 10 products on a page with a form field (used as quantity) as follows.

<input id="quantity" name="product[<?=$row1['sku'];?>]" type="text" size="2" maxlength="2" />

The user can enter the desired quantity of those products they are interested in, then the form post back to the same page. I want to populate the form field value="" with the value entered by the user. Usually done like this <?php echo $_POST['name'] ?>

But in this case the files names are like product[BGS-113468-001]

I have tried getting the values from the array as follows, but I can't seem to get it syntax right

<input id="quantity" name="product[<?=$row1['sku'];?>]" 
   type="text" size="2" maxlength="2" 

<?php 
	if(isset($_POST['updateform'])){ 
	   //$val = $_POST['product']['.$row1['sku'].'];
	    $val = "$_POST['product']['".$row1['sku']."']";
	      echo "value='".$val."'";
	   }
?>   

/>

I need help with the $val = line

I try in 2 ways and get these errors
I get these respective errors

Parse error: syntax error, unexpected T_STRING, expecting ']' in ...

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING ...

Thanks

//print_r($_POST['product']);

foreach ($_POST['product'] as $key => $value) {
    echo "$key:$value\n";
}

Try this

<input id="quantity" name="product[<?=$row1['sku'];?>]" 
   type="text" size="2" maxlength="2" 

<?php 
    $sku = $row1['sku'];
    if(isset($_POST['product'][$sku])) { 
          echo "value='{$_POST['product'][$sku]}'";
       }
?>

/>

The variable $sku isn't totally necessary, but it makes the code easier to read.

Try this

    if(isset($_POST['product'][$sku])) { 
          echo "value='{$_POST['product'][$sku]}'";
       }
?>

try this
$val = $_POST['product']."['".$row1['sku']."']";
