在重复字符数的下一行中打印不同的字符并打印星号

Question

我有一个字符串$string = "CONSTANTMAINONE";

我想打印不同的字符，并在重复字符数的下一行中打印星号。

C   O   N   S   T   A   M   I   E
*   *   *   *   *   *   *   *   *
    *   *       *   *           
        *                  
        *

我试过的

Loop the characters Add the character as a key and count as a value Then printed, but that output is not coming vertically and the question should be do not use table or pre tags

$string = "CONSTANTMAINONE";
$repeated_char = [];
for($i=0; $i<=strlen($string);$i++){
  if(!array_key_exists($string[$i], $repeated_char)){
     $repeated_char[$string[$i]] = 1;
  }else{
     $repeated_char[$string[$i]] += 1;
  }
}

到目前为止，输出为

C => 1
o => 1
N => 4
s => 1
T => 1
..etc..,

然后，打印字符

foreach($repeated_char as $key=>$val){
  echo $key. "&nbsp;";
  for($j=0; $j<$val; $j++){
    echo "*";
  }  
   echo "<br/>";
}

所以，我的代码的最终输出

C *
o **
N ****
S *
T **
A **
M *
I *
E *

这应该适合你：

（这里我使用 str_split() to create a array out of the string. After this i count all array values with array_count_values()。然后它只是一个简单的打印事情。首先我打印所有唯一值，然后我打印开始并递减 tmp 数组中的值）

<?php

    $string = "CONSTANTMAINONE";
    $array = str_split($string);
    $count = array_count_values($array);
    $tmp = $count;

    echo "<table border='1'><tr>";
        foreach($count as $k => $v)
            echo "<td>" . $k . "</td>";

        echo "</tr>";

        for($i = 0; $i < max($count); $i++) {
            echo "<tr>";
            foreach($tmp as $k => $v) {
                if($v >= 1)
                    echo "<td>*</td>";
                else
                    echo "<td></td>";
                $tmp[$k]--;
            }
            echo "</tr>";
        }
    echo "</table>";

?>

输出：

C   O   N   S   T   A   M   I   E
*   *   *   *   *   *   *   *   *
*   *   *   *   *   *   *   *   *
    *   *       *   *       
        *
