Print Each Row With A Different Color Php

So i'm exploring PHP and working on a web app. I display a table from my database. However, i want each row to be displayed in a different color. For example: row1 in green; row2 i

Solution 1:

Here's some simple code that will show different $cur_color on each iteration:

$colors = array('red', 'green', 'blue', 'yellow', 'black');
$i = 0;
while ($row = mysqli_fetch_array($stid1)) {
    $cur_color = $colors[$i % count($colors)];
    echo'$cur_color is ' . $cur_color;
    $i++;
}

Just add $cur_color to the style of your tr/td.

Solution 2:

You can try this code

<?php$username = 'root';
$pwd = '';
$db_name = 'fileattente';

$db = new mysqli('localhost', $username, $pwd, $db_name) ordie("Unable to connect.");
?><table><tr><th><spanclass="Style1">SERVICE</span></th><th><spanclass="Style2">NUMERO</span></th><th><spanclass="Style3">GUICHET</span></th><th><spanclass="Style4">EN ATTENTE</span></th></tr><?php$req_service_1="SELECT `LIBESERV`, `CODESERV`, `CODEGUIC` , `NOMBATTE` FROM `v_attente_service`";
  $stid1= mysqli_query($db, $req_service_1);
  $records = mysqli_fetch_array($stid1)
  $colors = array('red', 'green', 'blue', 'yellow', 'black');
  for($i=0; $i<$count($records); $i++){
  ?><trstyle="background-color: <?phpecho$colors[$i]; ?>"><td><span><?phpecho$row['LIBESERV'];?></span></td><td><?phpecho$row['CODESERV'];?></td><td><blink><?phpecho$row['CODEGUIC'];?></blink></td><td><?phpecho$row['NOMBATTE'];?></td></tr><?php
  }
  ?>

Solution 3:

Try echo like this

<?php$colors = Array("bfbfbf","cccc","fbfbff","00ffff","bffbff");

$x = 0;

while ( $row = mysqli_fetch_array($stid1)) 
{ 

  if(!isset($colors[$x])){
      $x = 0; //if color will less then records it will start from 0 again
   }

echo"<tr>
  <td style='color:#".$colors[$x]."'><span>".$row['LIBESERV']."</span></td>
  <td style='color:#".$colors[$x]."'>".$row['CODESERV']."</td>   
  <td style='color:#".$colors[$x]."'><blink>".$row['CODEGUIC']."</blink></td>
  <td style='color:#".$colors[$x]."'>."$row['NOMBATTE']."</td> 

   </tr>";


$x++;
}


?>

Solution 4:

This PHP code will generate a table with rainbow colors:

<?phpfunctionhue2rgb($t)
{
    if ($t < 0) $t += 1;
    if ($t > 1) $t -= 1;
    if ($t < 1/6) return6 * $t;
    if ($t < 1/2) return1;
    if ($t < 2/3) return (2/3 - $t) * 6;
    return0;
}
functioncolor_hex($hue)
{
    return sprintf('#%02x%02x%02x',
        round(255 * hue2rgb($hue + 1/3)),
        round(255 * hue2rgb($hue)),
        round(255 * hue2rgb($hue - 1/3))
    );
}

$rows = 100;
?><tablestyle="width:100%"><?phpfor ($i = 0; $i < $rows; $i++):?><trstyle="background:<?=color_hex($i / $rows)?>"><td>Row <?=$i + 1?></td></tr><?phpendfor?></table>

Solution 5:

Technique #1

<?php$rand = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f');
$color = '#'.$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)];

?>

Then echo out the $color value anywhere you need it. For example:

<bodystyle="background: <?phpecho$color; ?>;">

Technique #2

<?php printf( "#%06X\n", mt_rand( 0, 0xFFFFFF )); ?>

My favorite one is:

<?php$color = sprintf("%02x%02x%02x", mt_rand(0x22, 0xaa), mt_rand(0x22, 0xaa), mt_rand(0x22, 0xaa)); ?>
