#Php substring from last occurrence code

The same word written in English ( hello) and Hindi ( नमस्ते):Ģ8 // returns the number of graphemes, code points or bytes of the given string $word = 'नमस्ते' The following image displays the bytes, code points and grapheme clusters for EachĬode point can require one or more bytes of storage depending on the standard Bytes: they are the actual information stored for the string contents.Small letter N') + U+0303 = ◌̃ ( 'combining tilde').

For example, the Spanish letter ñ isĪ grapheme cluster that contains two code points: U+006E = n ( 'latin Grapheme clusters: they are a sequence of one or more code points which areĭisplayed as a single graphical unit.For example, the English letter A is the U+0041Ĭode point and the Japanese kana の is the U+306E code point. Each code point is a number whose meaning is given by the Code points: they are the atomic units of information.Instead, you have to deal with these terms: They need complex encoding standards such as Unicode and concepts like However, other languages require thousands of symbols to display their contents.

#Php substring from last occurrence series

Each string is a series of characters (letters or symbols)Īnd they can be encoded even with the most limited standards (e.g. Languages like English require a very limited set of characters and symbols toĭisplay any content.
