How to bold a variable?
提问by space ranger
How can I have text within a php variable be bold??
如何让 php 变量中的文本变粗？
function show_balance_header ($balance, $currency)
{
(string)$display_output = null;
$display_output = fees_main::display_amount(abs($balance), $currency, true);
return $display_output;
}
I want to bold $balance. Is there an easy way or do I need to edit display_amount?
我要大胆$balance。有没有简单的方法或者我需要编辑display_amount？
I've tried doing this:
我试过这样做：
"<b>".$balance"</b>"but this did not get the correct variable,
"<b>".$balance"</b>"但这没有得到正确的变量，
thanks in advance!!
提前致谢！！

answer is to edit the inner function display_amount using Raeki's suggestion, for future questions, i think you must edit the inner-most function as only editing function show_balance_header did not get the correct variable
答案是使用 Raeki 的建议编辑内部函数 display_amount，对于以后的问题，我认为您必须编辑最内部的函数，因为只有编辑函数 show_balance_header 没有得到正确的变量

Needs to be "<b>" . $balance . "</b>". Concatenate <b>to $balanceand concatenate again to </b>
需要"<b>" . $balance . "</b>"。连接<b>到$balance并再次连接到</b>
Edit:
Assuming this does the printing/formatting: fees_main::display_amount(abs($balance)
编辑：假设这会进行打印/格式化：fees_main::display_amount(abs($balance)
You want fees_main::display_amount('<b>' . abs($balance) . '</b>', $currency, true).
abs($balance) gets the absolute value as a number, and the concatenation (explained above) automatically casts them to strings. The rest of the parameters are passed the same way (unmodified, unbolded).
你要fees_main::display_amount('<b>' . abs($balance) . '</b>', $currency, true)。abs($balance) 以数字形式获取绝对值，并且连接（如上所述）会自动将它们转换为字符串。其余参数以相同方式传递（未修改、未加粗）。
(string)$display_output = null;is unnecessary
(string)$display_output = null;没有必要

On your element html, example:
在您的元素 html 上，例如：
<p> text <?php echo "<b>{$balance}</b>"; ?> text</p>
