Strip comma at end of loop

This is going to sound like a very beginner question, because it is. I am modifying some free code snippets to fit my use and stuck. It's probably a simple fix.

 

First here is the code. This is printing from a while loop.

<?php print("[". $current_month .",". number_format($remaining_balance, "2", ".", ",") . "],");?>

 

Here is the last remaining items from the loop at it comes to an end:

[343,14,495.86], [344,13,682.26], [345,12,863.91], [346,12,040.79], [347,11,212.87], [348,10,380.12], [349,9,542.52], [350,8,700.02], [351,7,852.61], [352,7,000.26], [353,6,142.94], [354,5,280.62], [355,4,413.26], [356,3,540.85], [357,2,663.34], [358,1,780.72], [359,892.95], [360,0.00], 

 

My question is kind of simple, how do I get it do the comma doesn't print on the last print? I need it to end like this: [359,892.95], [360,0.00]

 

Does that make sense? I don't know if I explained it well. I could really use some help! Thanks so much!

Hi JDest,

 

The way I would do this is buffer the output into a variable which will then allow you to strip the last , before you print it out as the final step.

 

E.g.

<?php
$buffer = "";
while($current_month<10) {
$buffer .= "[". $current_month .",". number_format($remaining_balance, "2", ".", ",") . "],";
}
print(substr($buffer, 0, -1)); //Remove the last character and print
?>

 

Hope that helps!

I would first confirm that the last character is comma itself, before trimming it. Just as a precaution that I don't accidentally delete any other character,

 

 

<?php
$buffer = "";
while($current_month<10) {
$buffer .= "[". $current_month .",". number_format($remaining_balance, "2", ".", ",") . "],";
}

if( substr("abcdef", -1) == ',')
print(substr($buffer, 0, -1)); //Remove the last character and print
?>
