如何用PHP删除字符串中出现的所有c2a0？

Question

I'm working with a CSV file which is exported from Excel.

I have a column that contains a value of 1 234,00. I need to get all whitespaces away from these kinds of columns with PHP and I've tried to do it with preg_replace("/\s*/","",$column) as well as with str_replace(" ","",$column). I was almost ready to lose it so I took a glance into the csv-file with a HEX-editor and noticed, that this space consist of two hex values, C2 and A0 which seems to be UTF-8 non-breaking space.

But I suck with encoding stuff and I'm still confused in finding a way to remove them. Any ideas?

Answer 1

$column = str_replace("\xc2\xa0", '', $column);
