I have a php echo with regular expression as in
echo preg_replace("/(\[|\])/", '', $paramValue);
I also want to make sure that any spaces are replaced aka if we have hello / world it becomes hello/world
I am not good with regex

Try this.
For just space you can use:
$string = str_replace(' ', '', $string);
For whitespaces you can use:
$string = preg_replace('/\s+/', '', $string);

Try this for removing space using regular expression.
$string = "hello / world";
$string = preg_replace('/\s+/', '', $string);
echo $string;
result:
hello/world

Thanks this is what I did
utag_data.ad_sec<?php echo ($i+1); ?> = "<?php
preg_replace("/(\[|\]) /", '', $paramValue);
$paramValue = str_replace(' ', '', $paramValue);
echo $paramValue;
?>";
