Question

I’m using trim() to get rid of characters from a string, but I get the warning message in the question title. How can I get rid of the warning, I’ve tried arranging the values in several different ways.

Code:

trim($temp2_description[0], "\xA0..\x0d..\x0a..\x09");

Also tried:

trim($temp2_description[0], "\x09..\x0a..\x0d..\xA0");

Hex values of the part of the string I want to trim:

a0
a0
a0
a0
a0
0d
0a
09
09
09
09
09
09
09
a0
0d
0a
09
09
09
09
09

How can I specify the trim function so it doesn’t return the warning message in my question title?

Answer 1

Your ranges are incorrect. They have to be start..endstart..endstart..end. You’ve got start..end..end..end.
