帶Fwrite（）的PHP循環並寫入文件

Question

我已經有一個循環，可將“梅森拼寫為梅森”打印到一個名為result.txt的文本文件中。

現在，我正在處理一個循環，以打印名稱中的每個字母“ m的十進制表示為109的二進制表示形式為1101101 m的十六進制表示為6d的m的八進制表示形式為155”。 我已經弄清楚了這部分，但是我需要對名稱中的每個字母進行遍歷，然后將表示形式寫入result.txt。

我想我需要使用一個foreach循環，該循環類似於我在第一個fwrite語句中使用的循環。 我不知道如何設置它。 這是我到目前為止的內容：

<?php
$name = "mason";
$nameLetterArray = str_split($name);

$results = fopen("results.txt", "w");

$output = " ";

foreach ($nameLetterArray as $nameLetter) {
$output .= $nameLetter." ";
}

fwrite($results, $name." is spelt ".$output);
fclose($results);

//here is what i need the loop to do for each letter in the name and save to 
//.txt file
$format = "Decimal representation of $nameLetterArray[0] is %d";
echo sprintf($format, ord($nameLetterArray[0]));
echo "<br>";
$format = "Binary representation of $nameLetterArray[0] is %b";
echo sprintf($format, ord($nameLetterArray[0]));
echo "<br>";
$format = "Hexadecimal representation of $nameLetterArray[0] is %x";
echo sprintf($format, ord($nameLetterArray[0]));
echo "<br>";
$format = "Octal representation of $nameLetterArray[0] is %o";
echo sprintf($format, ord($nameLetterArray[0]));
echo "<br>";

?>

如果您想在mason之后使用它，可以這樣編寫另一個循環：

<?php
$name = "mason";
$nameLetterArray = str_split($name);

$results = fopen("results.txt", "w");

$output = " ";

foreach ($nameLetterArray as $nameLetter) {
$output .= $nameLetter." ";
}

foreach($nameLetterArray as $nameLetter){

    $format = "Decimal representation of $nameLetter is %d";
    $output.="\n\n".sprintf($format, ord($nameLetter));

    $format = "Binary representation of $nameLetter is %b";
    $output.="\n\n".sprintf($format, ord($nameLetter));

    $format = "Hexadecimal representation of $nameLetter is %x";
    $output.="\n\n".sprintf($format, ord($nameLetter));

    $format = "Octal representation of $nameLetter is %o";
    $output.="\n\n".sprintf($format, ord($nameLetter));

}


//then write the result into the file

fwrite($results, $name." is spelt ".$output);
fclose($results);

//if you want to see the output in the browser replace the \n by <br>
$output=str_replace("\n","<br>",$output);
echo $output;

?>

我試過了，它起作用了。 請閱讀代碼中的注釋
