This will work

{
    $color="color:yellow";
}
else 
{
    $color="color:red";
}
 echo "<table><tr><td></td><td></td><td></td><td></td><td></td><td style='$color'>".$status ."</td></tr></table>";

How to change color of text based on $value

Store your calculation in a variable and then add a condition to your style to change colour vased on value of you variable. (e.g.:

<?php $value = round(100 * ($data[$tabele[$i]][$keys[$tabele[$i]][0]] + $data[$tabele[$i]]["RESERVED"] + $data[$tabele[$i]]["BIZ_AVAILABLE"]) / ArraySum($data[$tabele[$i]]) ,2)); ?>

<td style="font-weight: bold; color: <?php if($value<10):?>red<?php else:?>black<?php endif;?>;"><?php echo $value?>%</td>

How can i change the color of my text if it equals a given value in PHP

You need to use echo to display HTML inside PHP tags.

The font tag is not supported in HTML5. You're better off using p and changing its colour using CSS.

From your question, it seems like you're trying to loop through an array. It can be done like this:

<?php
foreach($arrayValues as $arrayValue) {
   $Danger = $arrayValue[2];
   if($Danger == "High") {
      echo'<p style="color: red;">'.$Danger.'</p>';
   }else if($Danger == "Medium") {
      echo'<p style="color: green;">'.$Danger.'</p>';
   }
}
?>

PHP: Change color of text based on $i

Put the color script under counting script and change $v to $i

<div id="body">
<ul>
    <li>Folder 1:<strong>
    <?php 
        // integer starts at 0 before counting
        $i = 0; 
        $dir = 'folder1/images/';
        if ($handle = opendir($dir)) {
            while (($file = readdir($handle)) !== false){
                if (!in_array($file, array('.', '..')) && !is_dir($dir.$file)) 
                    $i++;
            }
        }

        $color = "#000000";

        if (($i >= 0) && ($i <= 9))
           $color = "#E54028";
        else if (($i >= 9) && ($i <= 15))
           $color = "#F18D05";
        else if ($i >= 15)
           $color = "#61AE24";

        // prints out how many were in the directory
        echo "<span style=\"color: $color\">$i items</span>";
    ?>
    </strong></li>
</ul>
</div>

You might want to adjust the ranges for $i

Change font colour inside php echo statement depending on variable value

Try this:

<td><span style="font-family:Arial, Helvetica, sans-serif;<?php if($variable<0)echo "color:red"?>"><?php echo $variable; ?></span></td>

Note that the <font> tag was deprecated a long time ago so I replaced it with a <span> tag.

PHP setcookie function to remember the selected BackGround and Text Color

there are quite a few issues in the above code.You need to echo the colours, you should use the style declaration for the body tag (would be better as css!) and you ought to test that the various form elements are set in the POST array. Perhaps this might be of interest?!

<?php

    if( isset( $_POST["chk"], $_POST['NewBGColor'], $_POST['NewTextColor'] ) ) {
        setcookie( "BColor", $_POST['NewBGColor'], time()+3600 );  
        setcookie( "TColor", $_POST['NewTextColor'], time()+3600 );
    }

    $Bcolor = isset( $_COOKIE['BColor'] ) ? $_COOKIE['BColor'] : 'white';
    $TxtColor = isset( $_COOKIE['TColor'] ) ? $_COOKIE['TColor'] : 'black';

?>

<html>
    <head>
        <title>Cookie</title>
    </head>
    <body style="background:<?php echo $Bcolor;?>;color:<?php echo $TxtColor;?>">

        <form method="Post">

            Select A New BG Color:
            <Select name="NewBGColor" >
                <option value="WHITE">WHITE
                <option value="BLACK">BLACK
                <option value="RED">RED
                <option value="BLUE">BLUE
            </Select>

            Select A New Text color:

            <Select name="NewTextColor" >
                <option value="WHITE">WHITE
                <option value="BLACK">BLACK
                <option value="RED">RED
                <option value="BLUE">BLUE
            </Select>
            <input type="hidden" name="chk" value="true"/>
            <input type="submit"  value="submit" />

        </form>
    </body>
</html>

Or a slight modification that uses PHP to generate the HTML and remember the chosen values

<?php

    if( isset( $_POST["chk"], $_POST['NewBGColor'], $_POST['NewTextColor'] ) ) {
        setcookie( "BColor", $_POST['NewBGColor'], time()+3600 );  
        setcookie( "TColor", $_POST['NewTextColor'], time()+3600 );
    }

    $Bcolor = isset( $_COOKIE['BColor'] ) ? $_COOKIE['BColor'] : 'white';
    $TxtColor = isset( $_COOKIE['TColor'] ) ? $_COOKIE['TColor'] : 'black';

    $colours=array(
        'white','red','blue','black'
    );
?>

<html>
    <head>
        <title>Cookie</title>
    </head>
    <body style="background:<?php echo $Bcolor;?>;color:<?php echo $TxtColor;?>">

        <form method="Post">

            Select A New BG Color:
            <select name="NewBGColor" >
                <?php
                    foreach( $colours as $colour ){
                        $selected=$colour==$Bcolor ? ' selected' : '';
                        printf('<option value="%1$s"%2$s>%1$s',$colour,$selected);
                    }
                ?>
            </select>

            Select A New Text color:
            <select name="NewTextColor" >
                <?php
                    foreach( $colours as $colour ){
                        $selected=$colour==$TxtColor ? ' selected' : '';
                        printf('<option value="%1$s"%2$s>%1$s',$colour,$selected);
                    }
                ?>
            </select>
            <input type="hidden" name="chk" value="true"/>
            <input type="submit"  value="submit" />
        </form>
    </body>
</html>
