如何在file_get_contents和echo $ content之后为数字着色;

Question

Excuse me for my bad description of what I am looking to learn. I am new on coding sites.

I am trying to colorize the results of a variable. If the value is bigger than zero then color should be red.

My code is the following:

$content="
    <h2>---3 HH and 3 LL FIBO--- </h2>
        <code>
            <pre>".htmlspecialchars(file_get_contents("$path/$file"))."</pre>
        </code>";
echo $content;

And the result is something like this:

Balance | Equity | Used Mr | Usable Mr, % |

38.610,21 | 65.781,67 | 19.900,00 | 69,75 | 

Symbol |Amount|S/B| P/L | Gross P/L | 

EUR/CAD | 500 | S | 201,2 | 7.687,34 |

Is it possible to color the numbers if they are bigger than zero? Any ideas?

Answer 1

You can appy a preg_replace on your content to check for numbers and wrap it around for exemple!

$regex = '/((?!0)\d+((\.|\,)\d+)*)/';    
$content="
    <h2>---3 HH and 3 LL FIBO--- </h2>
        <code>
            <pre>".preg_replace($regex, '<span class="color-red">$1</span>', htmlspecialchars(file_get_contents("$path/$file")))."</pre>
        </code>";
echo $content;

(Haven't tested but might work)
