What is the Ruby function to remove all white space? Kind of like php's trim() ?

如果你只想删除前后的空格（比如PHP的修剪），你可以使用.strip ，但是如果你想删除所有的空格，你可以使用.gsub(/s+/, "") 。

s = "I have white space".delete(' ')

并模仿PHP的trim()函数：

s = "   I have leading and trailing white space   ".strip

Related answer:

"   clean up my edges    ".strip

returns

"clean up my edges"
