土耳其语段落中句子首字母大写

这可能对你有用

 $str= "YAĞMUR YAĞIYORDU. ŞEMSİYESİNİ 
 ÇIKARDI"; //Example sentence
function my_mb_ucfirst($str) {
   $fc = mb_strtoupper(mb_substr($str, 0, 1));
   return $fc.mb_substr($str, 1);
}
 echo  my_mb_ucfirst($str);

function ucfirst_turkish($str) {
  $tmp = preg_split("//u", $str, 2,    
 PREG_SPLIT_NO_EMPTY);
 return mb_convert_case(
    str_replace("i", "İ", $tmp[0]),     
  MB_CASE_TITLE, "UTF-8").
    $tmp[1];
}
$str= "YAĞMUR YAĞIYORDU. ŞEMSİYESİNİ 
 ÇIKARDI"; //Example sentence
echo ucfirst($str) ."'n";   
echo ucfirst_turkish($str); 

N。B:如果它不能工作，那么在这里检查一些土耳其语的例子http://php.net/manual/en/function.ucfirst.php

好吧，这是可怕的，但它的工作…至少对于您提供的字符串是这样。

我无法让你的preg_match在句号后得到那个' ' '，无论我怎么折腾，在你原来的例子中用mb_convert_case替换strtoupper()也没有做到这一点。

所以，我已经将它重构成一个针对字符的可怕循环，测试作为句子的句点。

<?php
// the string. i've made it lower case here to make the test simpler
$string = "yağmur yağiyordu. şemsiyesini çikardi"; //example sentence
// multibyte-safe splitting of the string into an array of chars. note that php arrays are by default one byte
// so simply accessing $string[3] may not give you the char you think.
$bodyArray = preg_split('//u', $string, -1, PREG_SPLIT_NO_EMPTY);
// us mb_convert_case to get the first char  of the sentence. you may wish to do some trimming here to 
// confirm that it's not a space..
$bodyArray[0] = mb_convert_case($bodyArray[0],MB_CASE_UPPER);
// the buffer to hold your capitalized string
$buffer  = "";
// each char
for($i=0;$i<count($bodyArray);$i++) {
    // if previous char was a period and the current char is not a space, uppercase the char
    if($ucflag && $bodyArray[$i] != " ") {
        $bodyArray[$i] = mb_convert_case($bodyArray[$i],MB_CASE_UPPER);
        $ucflag = false;
    }
    // if this char is a period, set a flag to uppercase the next non-space char
    if($bodyArray[$i] == ".") {
        $ucflag = true;
    }
    // add the char to the buffer
    $buffer .= $bodyArray[$i];
}
print $buffer;
