Remove space from regex expression in php

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 removing space using regular expression.

$string = "hello / world";
$string = preg_replace('/\s+/', '', $string);
echo $string;

result:

hello/world

Try this.

For just space you can use:

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

For whitespaces you can use:

$string = preg_replace('/\s+/', '', $string);
