Question

我需要使用HTML和PHP打印不同颜色（不是随机颜色）的字符串的每个字符。它几乎可以工作，但阵列的第一个字母是黑色的。你知道为什么吗？

<html>
    <?php
        $myString = ["s","t","r","i","n","g"];
        $myColors = ["blue","green","yellow","brown","gray","pink"];

        for ($i = 0; $i < count($myString); $i++) { 
            echo "$myString[$i] <span style='color:$myColors[$i]'</span>";
        }
    ?>
</html>

Answer 1

好像你没有正确关闭你的span标签，把你的字符串放在你的跨度中会有助于它的着色。

<?php
$myString = ["s","t","r","i","n","g"];
$myColors = ["blue","green","yellow","brown","gray","pink"];

for ($i = 0; $i < count($myString); $i++) { 
   echo "<span style='color:$myColors[$i]'>$myString[$i]</span>";
}

Answer 2

角色不在彩色范围内且你错过>：

echo "<span style='color:$myColors[$i]'>$myString[$i]</span>";

Answer 3

我认为您的HTML已损坏。您需要在$myString[$i]元素中加入<span>并正确关闭它。

$myString = ["s","t","r","i","n","g"];
$myColors = ["blue","green","yellow","brown","gray","pink"];

for ($i = 0; $i < count($myString); $i++) { 
   echo "<span style='color:$myColors[$i]'>$myString[$i]</span>";
}

Answer 4

<html>
<?php
$myString = ["s","t","r","i","n","g"];
$myColors = ["blue","green","yellow","brown","gray","pink"];

for ($i = 0; $i < count($myString); $i++) { 

   echo "<span style='color:$myColors[$i]'> $myString[$i] </span>";

}
?>
</html>
