How to format font style and color in echo
提问by ValleyDigital
I have a small snippet of code that I want to style from echo.
我有一小段代码，我想从 echo 中设置样式。
foreach($months as $key => $month){
if(strpos($filename,$month)!==false){
echo '<style = "font-color: #ff0000"> Movie List for {$key} 2013 </style>';
}
}
This is not working, and I've been looking over some resources to try to implement this. Basically I want font-family: Arial and font-size: 11px; and the font-color: #ff0000;
这不起作用，我一直在寻找一些资源来尝试实现这一点。基本上我想要 font-family: Arial 和 font-size: 11px; 和字体颜色：#ff0000;
Anyphp assistance would be helpful.

foreach($months as $key => $month){
if(strpos($filename,$month)!==false){
echo "<div style ='font:11px/21px Arial,tahoma,sans-serif;color:#ff0000'> Movie List for $key 2013</div>";
}
}

echo "<span style = 'font-color: #ff0000'> Movie List for {$key} 2013 </span>";
Variables are only expanded inside double quotes, not single quotes. Since the above uses double quotes for the PHP string, I switched to single quotes for the embedded HTML, to avoid having to escape the quotes.
变量只在双引号内展开，而不是单引号。由于以上对 PHP 字符串使用双引号，因此我为嵌入的 HTML 切换到单引号，以避免对引号进行转义。
The other problem with your code is that <style>tags are for entering CSS blocks, not for styling individual elements. To style an element, you need an element tag with a styleattribute; <span>is the simplest element -- it doesn't have any formatting of its own, it just serves as a place to attach attributes.
您的代码的另一个问题是<style>标签用于输入 CSS 块，而不是用于设置单个元素的样式。要为元素设置样式，您需要一个带有style属性的元素标签；<span>是最简单的元素——它没有任何自己的格式，它只是作为附加属性的地方。
Another popular way to write it is with string concatenation:
另一种流行的写法是字符串连接：
echo '<span style = "font-color: #ff0000"> Movie List for ' . $key . ' 2013 </span>';

Are you trying to echo out a style or an inline style? An inline style would be like
你是想呼应一种风格还是一种内联风格？内联样式就像
echo "<p style=\"font-color: #ff0000;\">text here</p>";

echo "<a href='#' style = \"font-color: #ff0000;\"> Movie List for {$key} 2013 </a>";

You should also use the style 'color' and not 'font-color'
您还应该使用样式 'color' 而不是 'font-color'
<?php
foreach($months as $key => $month){
if(strpos($filename,$month)!==false){
echo "<style = 'color: #ff0000;'> Movie List for {$key} 2013 </style>";
}
}
?>
In general, the comments on double and single quotes are correct in other suggestions. $Variables only execute in double quotes.
一般来说，双引号和单引号的注释在其他建议中都是正确的。$Variables 只在双引号中执行。
