It's like this:
foreach($arg['textarea'] as $row) is ALREADY tearing apart the
$arg['textarea'] into pieces.
So $row is "Hello"
When you print $row['body'], PHP is kinda stuck...
You've got a string, which is really a bunch of individual characters
run together.
You're trying to index it like an array.
So you MUST be trying to get at an individual character.
The index you've given is 'body', and PHP needs that to be a number:
0->H
1->e
2->l
3->l
4->o
The data-type conversion rules of PHP convert 'body' to the number 0.
So you're getting 'H' because you are really doing:
$row = "Hello";
echo $row[0];
Maybe what you REALLY wanted was:
//iterate through each 'textarea':
foreach($arg as $row){
echo $row['body'];
}
Or, perhaps:
foreach($arg['textarea'] as $row){
echo $row;
}
