Does ForEach Loop Take Only Original names of Arrays ?

Php Experts,

I got this array:

Step 1

[code]
//$radio_button_gender_options = array(‘Male’,’Female’,’Male To Female’,’Female To Male’);
$radio_button_gender_options[]=’Male’;
$radio_button_gender_options[]=’Female’;
$radio_button_tos_options = array(‘Yes’,’No’);
[/code]

Step 2
And I did this:

[code]
$value = $form_question_label;
$value_1 = str_replace(“”,”_”,”$value”); //Replaced Spaces to Underscores.
$value_2 = strtolower(“$value_1”); //Replaced Upper Case to Lower Case.

//$radio_button_gender_options = array(‘Male’,’Female’,’Male To Female’,’Female To Male’);
$current_radio_button_options = “$” . “radio_button_” . “$value_2” . “_options”;
$current_radio_button_option = “$” . “radio_button_” . “$value_2” . “_option”;
[/code]

Step 3
Therefore, this should work as the Array Name is correct:

[code]
foreach($current_radio_button_options as $current_radio_button_option) //Loop through the whole appropriate ‘Radio Buttons’ array.
{
echo “<input type=”radio” id=”$current_radio_button_option” name=”$value_2″ value=”$current_radio_button_option”>
<label_for=”$radio_button_gender_option”>$form_question_label</label><br>”;
}
[/code]

But I get error:
**Warning: Invalid argument supplied for foreach() in C:xampphtdocstestsearch_2.php on line 130**

Line 130 is this:

[code]
foreach($current_radio_button_options as $current_radio_button_option) //Loop through the whole appropriate ‘Radio Buttons’ array.
[/code]

It seems php does not recognise this variable as array:

[code]
$current_radio_button_options
[/code]

It should. Look at step 2 above.
The original Array is actually this:

[code]
//$radio_button_gender_options = array(‘Male’,’Female’,’Male To Female’,’Female To Male’);
$radio_button_gender_options[]=’Male’;
$radio_button_gender_options[]=’Female’;
$radio_button_gender_options[]=’Male To Female’;
$radio_button_gender_options[]=’Female To Male’;
$radio_button_tos_options = array(‘Yes’,’No’);
[/code]

But remember at step 2, I did this:

[code]
//$radio_button_gender_options = array(‘Male’,’Female’,’Male To Female’,’Female To Male’);
$current_radio_button_options = “$” . “radio_button_” . “$value_2” . “_options”;
$current_radio_button_option = “$” . “radio_button_” . “$value_2” . “_option”;
[/code]

So it is like say, the array is called “tom”.
But instead of looping (foreach) through Tom, I am doing it like this:

bert = tom
Now loop foreach thru ‘bert’.
Now, doesn’t foreach loop work that way ? Do you have to give the original Array Name or what ?

Why am I doing it like this ? There is a reason for it. Not pasting here the full code as it is too long. If you look at the full code then you will see I have to do it like this.
