在回显表中更改字体大小

Question

I want to modify the font size based on a echo table. Here you can see me code...

    echo "<table>";
    foreach($pdo -> query($abgÜbersicht) as $row){
        echo "<tr>";
        echo "<td>".$row['Spiel']."</td>";
        echo "</tr>";
    }
    echo "</table>";

I think I have to fill in something like

<font-size: "xy"> 

But I am not really sure how to write it correctly regarding to the correct quote signs.

Answer 1

You need to use the style HTML property.

echo "<table>";
foreach($pdo -> query($abgÜbersicht) as $row){
    echo "<tr>";
    echo "<td style=\"font-size: xy;\">".$row['Spiel']."</td>";
    echo "</tr>";
}
echo "</table>";

Answer 2

You can do it in two ways inline style and with style tag or separate file. Lets first do it in the first way:

echo "<table>";
    foreach($pdo -> query($abgÜbersicht) as $row){
        echo "<tr>";
        echo "**<font size='16px' color='magenta' family='monospace'>**<td>".$row['Spiel']."</td>**</font>**";
        echo "</tr>";
    }
    echo "</table>";

the second way is to put style tag and give class to td.

      echo "<table>";
            foreach($pdo -> query($abgÜbersicht) as $row){
                echo "<tr>";
                echo "<td **class='edit'**>".$row['Spiel']."</td>";
                echo "</tr>";
            }
             ?>
            <style type='text/css'>
              .edit{ color:magenta; font-size:16px; /*and whatever you 
              want*/
               </style>

After this line how to write it correctly regarding to the correct quote signs. i would like to share something about quotes in php . it was prepared few month back but while i fail to post . Most of new developer will not know where to use single quotes and double quotes and how it behave .

1 : First of all you need to know the difference bewtween single quotes and double quotes and when it's used

Single quotes

2 : Inside the single quotes everything consider as string .

$message1 = '<div style="color:#ff0000"> Message 1 </div>';

2.1 : Above example you can use double quotes inside single quotes but you should not use single quotes inside single quotes . if you need to use you need to escape it properly using backward slash (\\) . like this $message1 = '<div style=\\'color:#ff0000\\'> Message 1 </div>';

Double quotes

3 : Inside the double quotes we can use single quotes $message1 = "<div style='color:#ff0000'> Message 1 </div>; but should not use double quotes inside the double quotes .if you need you need to ecape it properly like this like this $message1 = "<div style=\\"color:#ff0000\\"> Message 1 </div>";

4 : $message1 = '<div style="color:#ff0000">$error</div>';

4.1 : In above example $error will consider as string . it will not echo the value of variable ,because it's inside the single quotes .

overcome :

you can concatenate like this

$message1 = '<div style="color:#ff0000">'.$error.'</div>';

5 : $message1 = "<div style="color:#ff0000">$error</div>";

5.1 : In above example $error will consider as variable because it's inside the dobule quotes .

6 : $message1 = "<div style="color:#ff0000">'$error'</div>";

6.1 : In above example $error consider as variable and also it give the value with enclosed by single quotes .
