Need Help with Code

andyy15

I am attempting to create a comma delimited string that I can convert to an array using explode();.

I have the following code:

$cPath_new_a = tep_get_path($categories['categories_id']);
$cPath_new_b  = str_replace("cPath=", "", "$cPath_new_a");
$cPath_new_c  = str_replace("_", "", "$cPath_new_b");
$cPath_new_d = substr("$cPath_new_c", -2, 2); 

$cPath_new_e = $cPath_new_d . ",";

echo $cPath_new_e;

This outputs 23,53,

I need it to output 23,53

Using the substr($cPath_new_e, 0, -1); and/or rtrim() method to remove the last character
for some reason removes all of the commas.

Am I approaching this the right way?

I really appreciate any feedback.

Isn't this line:

$cPath_new_e = $cPath_new_d . ",";

adding the extra comma at the end? What if you remove that line?

Altnernatively, [man]rtrim/man is the way to go:

$string = rtrim($string, ',');

Hi bradgrafelman,

I put in

$cPath_new_e = $cPath_new_d . ",";

on purpose to enter in the comma. Removing it will produce 2353 which is not what I wanted :queasy:

    	  

$cPath_new_a = tep_get_path($categories['categories_id']);
$cPath_new_b  = str_replace("cPath=", "", "$cPath_new_a");
$cPath_new_c  = str_replace("_", "", "$cPath_new_b");
$cPath_new_d = substr("$cPath_new_c", -2, 2); 
$cPath_new_e = $cPath_new_d . ",";

$cPath_new_f = rtrim($cPath_new_e, ',');

like I said previously for some reason removes all commas and I get 2353.

Doesn't this work:

$cPath_new_a = tep_get_path($categories['categories_id']);
$cPath_new_b  = str_replace("cPath=", "", "$cPath_new_a");
$cPath_new_c  = str_replace("_", "", "$cPath_new_b");
$cPath_new_d = substr("$cPath_new_c", -2, 2); 
$cPath_new_e = $cPath_new_d;

echo $cPath_new_e;

Hi rowanparker,
No, that would output 2353.

ok I shortened my code down to this:

$cPath_new_a = $categories['categories_id']. ","; 
$cPath_new_b = rtrim($cPath_new_a , ',');  

$cPath_new_c = $cPath_new_b; 

echo $cPath_new_c;

However, same issue that outputs 2353. What am I missing here?

Let me try to explain things:
$categories['categories_id'] pulls a sub category ID out of the database based on what main category the user is in. The example I have been using is a main category with 2 subcategories 23 and 53. $categories['categories_id'] alone echos 2353. I want to make this into an array that contains 23 and 53.

I thought the best way to accomplish this would be to add a , to make the string 23,53, then remove the last , then use explode(); to convert the comma delimited string into an array. However rtrim/substr both are not working for me. Is there some way to convert $cPath_new_a into an actual string within the code (not a dynamic variable) then apply rtrim or substr? Or am I approaching this whole thing incorrectly?
