What is the name of the method that erases all blank characters in the string?

I'm looking for a method to erase blank characters such as trim in php.

Ruby has pretty much everything already made, so I'm sure it's somewhere, but I don't know the name

If you want to erase the blank character at the front/back, like PHP's trim, you can use strip

irb(main):001:0> mystr = "   hello     "
=> "   hello     "
irb(main):002:0> puts mystr
   hello     
=> nil
irb(main):003:0> puts mystr.strip
hello
=> nil
irb(main):004:0>

Use .gsub(/\s+/, "") to remove blank characters from the entire string

irb(main):001:0> mystr = "   hello Ruby    "
=> "   hello Ruby    "
irb(main):002:0> puts mystr.strip
hello Ruby
=> nil
irb(main):003:0> puts mystr.gsub(/\s+/, "")
helloRuby
=> nil
irb(main):004:0>
