在php上用星号计数单词

Question

我有一个用明星字符来计数单词的代码，结果是这样的：

Sentence "Today is Monday" have :
Count word = 3 word
Word-1 :Today
Word-2 :is
Word-3 :Monday

以及源代码：

<?php
$sentence = "Today is Monday";
$word=explode(" ", $sentence);
$count = count(explode(" ", $sentence));
//$count2 = count(explode(" ", $word));
echo "Sentence <b>\"".$sentence."\"</b> have : <br>";
echo "Count word = $count<br>\n";
echo "Word-1 :".$word[0]."<br>";
echo "Word-2 :".$word[1]."<br>";
echo "Word-3 :".$word[2]."<br>";
?>

结果，我想要这样：

Today is Monday
count word = 3 word

* * * * * = Today
* * = is
* * * * * * = Monday

Answer 1

试试下面的代码。

$sentence = "Today is Monday";
$word=explode(" ", $sentence);
$count = count(explode(" ", $sentence));
//$count2 = count(explode(" ", $word));
echo "Sentence <b>\"".$sentence."\"</b> have : <br>";
echo "Count word = $count<br>\n";
echo str_repeat('*', strlen($word[0])) . " = " . $word[0] . "<br>";
echo str_repeat('*', strlen($word[1])) . " = " . $word[1] . "<br>";
echo str_repeat('*', strlen($word[2])) . " = " . $word[2] . "<br>";

输出：

Sentence "Today is Monday" have :
Count word = 3
***** = Today
** = is
****** = Monday

Answer 2

重复和斯特伦函数应该可以帮助您这样做：

foreach ($word as $w) {
    echo sprintf('%s = %s<br>', str_repeat('* ', strlen($w)), $w);
}

Answer 3

你也可以试试这个

 <?php $sentence = "Today is Monday";
 $word=explode(" ", $sentence);
 $count = sizeof($word);
 echo "Sentence <b>\"".$sentence."\"</b> have : <br>";
 echo "Count word = $count<br>\n";
 $i=0;
 while($i<$count){
 echo str_repeat('*', strlen($word[$i])) . " = " . $word[$i] . "<br>";
 $i++;
 }
 ?>
