来自 mysql 数据库的 PHP 颜色表

Question

我的 echo '<tr style="background-color: . $color . '">'; 遇到一些问题它不断给我Parse error: syntax error, unexpected 'background' (T_STRING) in C:\xampp\htdocs\test.php line 146而且我对 php 还很陌生，所以我不知道我能做什么。

我使用这段代码的目的是从mysql数据库中的列中获取一些信息，然后将其显示为网站中的表格(我已经修复了，但我需要颜色才能工作)，然后它将在数据库中的某些值之后对某些表行进行着色。

P.S:这不是我的全部代码。

希望有人能帮忙，谢谢。

 while($row = mysql_fetch_array($rs)) {


if ( ($row['Flyttet'] == "NEI") && ($row['Slettet'] != "JA") && ($row['Delt'] != "NEI") ) {
    $red ='#ff0000';    
}
else {
    $red = false;
}

if ( (($row['Flyttet'] == "NEI") && ($row['Slettet'] != "NEI") && ($row['Delt'] != "JA")) || (($row['Flyttet'] == "JA") && ($row['Slettet'] != "NEI") && ($row['Delt'] != "JA"))  ) {
    $gul ='#FFFF00';    
}
else {
    $gul = false;
}

if ( ($row['Flyttet'] == "JA") && ($row['Slettet'] != "NEI") && ($row['Delt'] != "NEI") ) {
    $blue ='#1E90FF';    
}
else {
    $blue = false;
}

if ( ($row['Flyttet'] == "NEI") && ($row['Slettet'] != "NEI") && ($row['Delt'] != "JA") ) {
    $green ='#3CB371';    
}
else {
    $green = false;
}


$color = ";
if(!$red && !$gul && !$blue) $color = $green;
if(!$red && !$gul && !$green) $color = $blue;
if(!$red && !$green && !$blue) $color = $gul;
if(!$green && !$gul && !$blue) $color = $red;

    //Første kolone som skal vises
    echo '<tr style="background-color: . $color . '">';
    echo "<td>" . utf8_encode($row['ID']) . "</td>";
    echo "<td>" . utf8_encode($row['Vsite']) . "</td>";

    echo "<td>" . utf8_encode($row['Varenr']) . "</td>";
    echo "<td>" . utf8_encode($row['Server']) . "</td>";
    echo "<td>" . utf8_encode($row['Sistoppdatert']) . "</td>";
    echo "</tr>";

您初始化变量color错误。 它必须是$color = "";。

$color = "";
    if(!$red && !$gul && !$blue) $color = $green;
    if(!$red && !$gul && !$green) $color = $blue;
    if(!$red && !$green && !$blue) $color = $gul;
    if(!$green && !$gul && !$blue) $color = $red;

    //Første kolone som skal vises
    echo '<tr style="background-color:' . $color . '">';
    echo "<td>" . utf8_encode($row['ID']) . "</td>";
    echo "<td>" . utf8_encode($row['Vsite']) . "</td>";
    echo "<td>" . utf8_encode($row['Registrar']) . "</td>";
    echo "<td>" . utf8_encode($row['Eier']) . "</td>";
    echo "<td>" . utf8_encode($row['NS']) . "</td>";
    echo "<td>" . utf8_encode($row['A']) . "</td>";
    echo "<td>" . utf8_encode($row['MX']) . "</td>";
    echo "<td>" . utf8_encode($row['Flyttet']) . "</td>";
    echo "<td>" . utf8_encode($row['Slettet']) . "</td>";
    echo "<td>" . utf8_encode($row['Delt']) . "</td>";
    echo "<td>" . utf8_encode($row['Behkd']) . "</td>";
    echo "<td>" . utf8_encode($row['Varenr']) . "</td>";
    echo "<td>" . utf8_encode($row['Server']) . "</td>";
    echo "<td>" . utf8_encode($row['Sistoppdatert']) . "</td>";
    echo "</tr>";

    }
