avoid insert duplicate batch entry?

[Yohanne]

Hi Coders,

 

any idea how to avoid duplicate entry? ex.. numbers below that i want to insert in just one entry or single line and now i don't want to duplicate the numbers inside the comma? is this possible to trigger to avoid duplicate batch numbers.

Thanks

<?php

$string = "123,456,123";

$split = explode(',',$string);

$split = array_unique($split);

$string = implode(',',$split);



echo $string;



?>

Thanks Jairathnem,

 

and okay.. i gut your idea and its good to be close the situation.  but i only use one input and only comma are the border to identify the unique.

What do you mean by one input?

 

Jairathnem code will filter out any duplicated numbers in the comma delimited list. Which is what your original question was
