What is the difference between the iconv_strlen, mb_strlen and strlen functions?
And what is each used for in the real world?
The difference of
strlen()tomb_strlen()is, that the second respects multibyte characters. This means, that this is the real character count. The first one assumes, that the string is always in ascii, what also means, that it always returns the size in bytes (very useful when handling binary “strings”).As far as I can see
iconv_strlen()is quite similar tomb_strlen(), but fails on bad character sequences, in contrast tomb_strlen(), that just ignores them. And it uses theiconv-library (obviously ;)).
