[英]Print array with alternate colour in PHP
I have an array,我有一个数组,
$arr = arrary("Pune","Nashik","Mumbai");
I want to display Pune
in red colour, then on the next line Nashik
will be blue and the last line will have Mumbai
in green.我想以红色显示Pune
,然后在下一行Nashik
将显示为蓝色,最后一行将Mumbai
显示为绿色。 How do I do this using a " while loop ".我如何使用“ while 循环”来做到这一点。
Like,喜欢,
Pune (in red)
Nashik (in blue)
Mumbai (in green)
Why don't you simply build the logic into the array, eg为什么不简单地将逻辑构建到数组中,例如
$arr = array(
'Pune' => '#ff0000',
'Nashik' => '#0000ff',
'Mumbai' => '#00ff00'
);
Then, when you loop over it, use CSS to display the colours.然后,当你循环它时,使用 CSS 来显示颜色。
<?php foreach ($arr as $something => $colour) : ?>
<p style="color:<?php echo $colour ?>"><?php echo $something ?></p>
<?php endforeach ?>
You could also use CSS class names instead of hex colour values.您还可以使用 CSS class 名称而不是十六进制颜色值。
Also, a while
loop is hardly the best option for iterating over an array.此外, while
循环并不是遍历数组的最佳选择。
