PHP check every string separately in a foreach loop if it is equal-CodePudding

I would like to make my table more viewable. My table will be created from a database. And it's simple like:

Test1 | Test2 ...
---------------
Yes   | No    ...
Yes   | Yes   ...
No    | Yes   ...
Yes   | No    ...

And I want that all Yes'es are green and all No's are red.

The entries of the table will be created by a foreach loop.

I have an example but I used array instead because it's easier to show the problem. But I think it's the same principle. (I only tested the first row)

<!DOCTYPE html>
<html>
<body>

<?php
$contacts = array('N', 'J', 'N', 'N', 'J');
$demo_str = 'J';
?>

<table style="border-radius: 10px; overflow: hidden; background: #fff; box-shadow: 5px 5px 5px #dfdfdf;" >
    <thead>
        <tr>
            <td style="width: 180px;">Test1</td>
            <td style="width: 105px;">Test2</td>
            <td style="width: 100px;">Test3</td>
            <td style="width: 80px; ">Test4</td>
            <td style="width: 80px; ">Test5</td>
            <td style="width: 98px; ">Test6</td>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($contacts as $contact): ?>
        <tr>
            <td><?php  if ($demo_str == $contact) {
      echo "<html>
<head>
     <style>
     .redifnull1 {
         color: green;
     }
    </style>
</head>
</html>";
  }
  else {
      echo "<html>
<head>
     <style>
     .redifnull1 {
         color: red;
     }
    </style>
</head>
</html>";
  };
     ?><strong ><?=$contact['test1']?></strong></td>
                <td><?=$contact['test2']?></td>
                <td><?=$contact['test3']?></td>
                <td><?=$contact['test4']?></td>
                <td><?=$contact['test5']?></td>
                <td><?=$contact['test6']?></td>
            </tr>
            <?php endforeach; ?>
        </tbody>
    </table>

</body>
</html>

And the problem is, that it only compare with "$contacts = array('N', 'J', 'N', 'N', --->'J'<---);", so with the last "letter" and everything is green, if the last one is "N" everything is red.

Does anyone knows how a can solve this problem? Thank you very much,

best

Creating different <style> blocks doesn't work like this. All the styles in the page are merged, and the last style for a selector takes precedence.

You also can't have multiple <html> and <head> tags in a document. You're creating new ones each time through the loop.

Instead, create a single style block that defines two classes, redifnull and greenifnull. Then use the appropriate class in your table rows.

<!DOCTYPE html>
<html>
<head>
<style>
    .rediffnull {
        
        color: red;
    }

    .greenifnull {
        color: green;
    }
</head>
<body>

<?php
$contacts = array('N', 'J', 'N', 'N', 'J');
$demo_str = 'J';
?>

<table style="border-radius: 10px; overflow: hidden; background: #fff; box-shadow: 5px 5px 5px #dfdfdf;" >
    <thead>
        <tr>
            <td style="width: 180px;">Test1</td>
            <td style="width: 105px;">Test2</td>
            <td style="width: 100px;">Test3</td>
            <td style="width: 80px; ">Test4</td>
            <td style="width: 80px; ">Test5</td>
            <td style="width: 98px; ">Test6</td>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($contacts as $contact): ?>
        <tr>
            <td>
            <td><strong greenifnull" : "redifnull" ?>"><?=$contact['test1']?></strong></td>
                <td><?=$contact['test2']?></td>
                <td><?=$contact['test3']?></td>
                <td><?=$contact['test4']?></td>
                <td><?=$contact['test5']?></td>
                <td><?=$contact['test6']?></td>
            </tr>
            <?php endforeach; ?>
        </tbody>
    </table>

</body>
</html>

Try it like this:

<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.green { color: green; }
.red { color: red; }
</style>
</head>
<body>

<?php
$contacts = array('N', 'J', 'N', 'N', 'J');
$demo_str = 'J';
?>

<table style="border-radius: 10px; overflow: hidden; background: #fff; box-shadow: 5px 5px 5px #dfdfdf;" >
    <thead>
        <tr>
            <td style="width: 180px;">Test1</td>
            <td style="width: 105px;">Test2</td>
            <td style="width: 100px;">Test3</td>
            <td style="width: 80px; ">Test4</td>
            <td style="width: 80px; ">Test5</td>
            <td style="width: 98px; ">Test6</td>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($contacts as $contact): ?>
        <tr>
            <td>
                <strong ><?=$contact['test1']?></strong>
            </td>
            <td><?=$contact['test2']?></td>
            <td><?=$contact['test3']?></td>
            <td><?=$contact['test4']?></td>
            <td><?=$contact['test5']?></td>
            <td><?=$contact['test6']?></td>
       </tr>
            <?php endforeach; ?>
