Example of converting php Chinese characters to pinyin

This article mainly introduces the example of converting Chinese characters into pinyin in php. For more information, see The code is as follows:
Class Helper_Spell {
Public $ spellArray = array ();

Static public function getArray (){
Return unserialize(file_get_contents('pytable_without_tune.txt '));
}
/**
* @ Desc get the first letter of the string
* @ Param $ string the string to be converted
* @ Param $ whether isOne is the first letter
* @ Param $ whether the upper is converted to uppercase
* @ Return string
*
* For example, getChineseFirstChar ('I am the author') must start with all letters and lowercase letters.
* Return "wo"
*
* For example, getChineseFirstChar ('I am the author', true) first letter + lower case
* Return "w"
*
* For example: getChineseFirstChar ('I am the author', true, true) first letter + uppercase
* Return "W"
*
* For example, getChineseFirstChar ('I am the author', false, true) must start with all letters and uppercase letters.
* Return "WO"
