我有一个包含很多单词的数组，但有些句子是大写的。例如：

THIS SENTENCE IS UPPERCASE

this sentece is in lowercase

我想把这两个句子分开\r\n，但我找不到怎么做

这是我如何检索这个数组：

    $result_pk_info = array();
    while ($row = odbc_fetch_array($sql_pk_info))
    {
        $opisanie = iconv("cp1257", "UTF-8", trim($row['opis']));
        $id = iconv("cp1257", "UTF-8", trim($row['pacientid']));
        $date = iconv("cp1257", "UTF-8", trim($row['data']));

        $desc = explode('@#$', $opisanie);

        $all_info = "<tr><td>".$desc[1]."</td></tr>";

        $result_pk_info[] = $all_info;
    }

在$desc我有单词数组，我想在其中搜索和拆分大写和小写。

那么任何人都可以帮助我吗？

UPD我有类似这种结构的文本： SENTENCE IN UPPERCASE Sentece in lower case

此功能是您正在寻找的：

    function split_upper_lower ($string)
{
    $words = explode (' ', $string);
    $i = 0;
    foreach ($words as $word)
    {
        if (ctype_upper ($word))
            $new_string_array[++$i]['type'] = 'UPPER';  
        else
            $new_string_array[++$i]['type'] = 'LOWER';
        $new_string_array[$i]['word'] = $word;
    }
    $new_string = '';
    foreach ($new_string_array as $key => $new_word)
    {
        if (!isset ($current_mode))
        {
            if (ctype_upper ($new_word))
                $current_mode = 'UPPER';
            else
                $current_mode = 'LOWER';
        }
        if ($new_word['type'] === $current_mode)
        {
            $new_string .= $new_word['word'];
            if (isset ($new_string_array[$key + 1]))
                $new_string .= ' ';
        }
        else
        {
            $new_string .= "\r\n" . $new_word['word'];
            if (isset ($new_string_array[$key + 1]))
                $new_string .= ' ';
            if ($current_mode === 'UPPER') $current_mode = 'LOWER';
            else $current_mode = 'UPPER';
        }
    }
    return $new_string;
}

测试它br：

$string = 'HI how ARE you doing ?';
echo split_upper_lower ($string);

输出 ：

HI 
how 
ARE 
you doing ?

使用 preg_match： http: //php.net/manual/en/function.preg-match.php

$string = 'THIS SENTENCE IS UPPERCASE';
$string2 = 'this sentece is in lowercase';

if(preg_match ( '/[A-Z ]$/' , $string))
{
echo 'uppercase';
}
else
{
echo 'lowercase';
}

通过 $desc 在循环中使用它。其中 $string 是包含一个字符串的数组的一个元素。

/[AZ ]$/ 将匹配所有带有空格的大写字母。您可以升级您的正则表达式以从字符串中获取其他内容。

这可以使用preg_match_all(). 使用以下代码，

$result_pk_info = array();
    while ($row = odbc_fetch_array($sql_pk_info))
    {
        $opisanie = iconv("cp1257", "UTF-8", trim($row['opis']));
        $id = iconv("cp1257", "UTF-8", trim($row['pacientid']));
        $date = iconv("cp1257", "UTF-8", trim($row['data']));

        $desc = explode('@#$', $opisanie);
        //converting $desc array to string 
$string = implode(" " , $desc);
//Upper case Matching
$upprCase = preg_match_all('/[A-Z]/', $string, $uprmatches, PREG_OFFSET_CAPTURE);

if($upprCase){
foreach ($uprmatches as $match)
{
    foreach($match as $value)
    //Iam a uppercase
    print $UpperCase = $value[0];
}}

//Splitting with \r\n
print "\r\n";

//lower case matching
$lowrCase = preg_match_all('/[a-z]/', $string, $lowrmatches, PREG_OFFSET_CAPTURE);
if($lowrCase){
    foreach ($lowrmatches as $match)
    {
        foreach($match as $value)
            //Iam a lowercase
            print $lowerCase = $value[0];
    }}
}

如果我理解你的问题，你可以这样做......

$desc = array ("abcd","ABCD","bbb","B");

foreach($desc as $value) {

     if(ctype_upper($value)) {
      // character is upper
     } else {

      // character is lower

    }

}
