Question

这有什么问题：

<?php echo '<div id="testID"> <p class="testClass">
<?php echo $textToPrint; ?> </p> </div>'; ?>

我尝试了innerHTML赋值，但它打印出一些乱码（放置一些额外的字符，而不仅仅是$ textToPrint中的字符，这是字符串php变量）。

这个完美无缺：

<?php echo '<h3>helloe</h3><br><p class="testClass">messing around</p>
<br>'; ?>

谢谢！

Answer 1

你不需要两个回音就可以试试

  <?php echo '<div id="testID"> <p class="testClass">' . $textToPrint .'</p> </div>'; ?>

Answer 2

<?php echo '<div id="testID"> <p class="testClass">'; ?> #<--missing
<?php echo $textToPrint; ?> </p> </div> <!--remove-->

Answer 3

你应该关闭php标签和引号：

<?php echo '<div id="testID"> <p class="testClass">'; ?>
<?php echo $textToPrint . '</p> </div>'; ?>

或者用完整的PHP中的一句话来说：

<?php echo '<div id="testID"><p class="testClass">'.$textToPrint.'</p></div>'; ?>

或者只用PHP中的php变量的html

<div id="testID"><p class="testClass"><?php echo $textToPrint;?></p></div>

Answer 4

你可以尝试一下

$roleInstances = Get-AzureRole -ServiceName $cloudServiceName -Slot Production -InstanceDetails
Write-Output "Retrieved all role instances for cloud service: $cloudServiceName. Number of instances: " + $roleInstances.Count

# Group instances per update domain
$roleInstanceGroups = $roleInstances | Group-Object -AsHashTable -AsString -Property InstanceUpgradeDomain
Write-Output "Number of update domains found: " + $roleInstanceGroups.Keys.Count

# Visit each update domain
foreach ($key in $roleInstanceGroups.Keys)
{
    $count = $perDomainInstances.Count;
    Write-Output "Rebooting $count instances in domain $key"    

    $perDomainInstances = $roleInstanceGroups.Get_Item($key)

    foreach -parallel($instance in $perDomainInstances)
    {
        $instanceName = $instance.InstanceName
        Write-Output "Rebooting instance $instanceName"

        Reset-AzureRoleInstance -ServiceName $cloudServiceName -Slot Production -InstanceName $instanceName -Reboot -ErrorAction Stop
    } 
}

祝你好运！
