PHP gets the string first letter method, PHP gets the string

This example describes how PHP obtains the first letter of a string. Share to everyone for your reference. The implementation method is as follows:

<?php$limit = Array (//gb2312 phonetic sort Array (45217,45252),//a Array (45253,45760),//b Array (45761,46317),//c Array (46 318,46825),//d Array (46826,47009),//e Array (47010,47296),//f Array (47297,47613),//g Array (47614,48118),//h array (0,0),//i Array (48119,49061),//j Array (49062,49323),//k Array (49324,49895),//l Array (49896,50370),//m Array ( 50371,50613),//n Array (50614,50621),//o Array (50622,50905),//p Array (50906,51386),//q Array (51387,51445),//r arr Ay (51446,52217),//s Array (52218,52697),//t Array (0,0),//u Array (0,0),//v Array (52698,52979),//w Array (52 980,53688),//x Array (53689,54480),//y Array (54481,55289),//z); $str = "A: This is a test program 1"; $str = Iconv ("UTF-8", "gb2312", $ STR); Echo $str. "
"; $i =0;while ($i
 
  
   = ' B0 ')    {//The beginning of the kanji $t =getletter (Hexdec (Bin2Hex (substr ($str, $i, 2))); printf ("%c", $t ==-1?    ' * ': $t);  $i +=2;    } else{printf ("%s", substr ($str, $i, 1));  $i + +;  }}function Getletter ($num) {global $limit;  $char _index=65;      foreach ($limit as $k = + $v) {if ($num >= $v [0] && $num <= $v [1]) {$char _index+= $k;    return $char _index; }} return-1;}? >
