带有xml数据的php字符串变量 - php string variable with xml data

php string variable with xml data

我有一个字符串变量，其中包含一些xml数据：

$temp = '<chart manageResize="1" dateFormat="dd/mm/yyyy" ganttLineColor="CCCCCC" ganttLineAlpha="20" gridBorderAlpha="20" showTaskNames="1" hoverCapBgColor="F1F1F1" hoverCapBorderColor="333333" paletteThemeColor="333333" hoverBandColor="3d3d3d" hoverBandAlpha="95" showGanttPaneHorizontalHoverBand="0" showGanttPaneVerticalHoverBand="0">'n'
<categories bgColor="333333"  baseFont="Arial" baseFontCOlor="FFFFFF" baseFontSize="12" showhoverband="0" >'n'
    <category start="1/1/2005" end="31/5/2005" align="center" name="Sales Territory Assignment" fontColor="ffffff" isBold="1" fontSize="16" />'n'
</categories>'n'
<categories font="Arial" fontColor="ffffff" isBold="1" fontSize="12" bgColor="333333">'n'
    <category start="1/1/2005" end="31/1/2005" name="January" />'n'
    <category start="1/2/2005" end="28/2/2005" name="February" />'n'
    <category start="1/3/2005" end="31/3/2005" name="March" />'n'
    <category start="1/4/2005" end="30/4/2005" name="April"/>'n'
    <category start="1/5/2005" end="31/5/2005" name="May" />'n'
</categories>'n'
<processes headerbgColor="333333" fontColor="ffffff" fontSize="12" bgColor="333333" align="right" >'n'
    <process Name="Tom" id="1" />'n'
    <process Name="Harry" id="2" />'n'
    <process Name="Mary" id="4" />'n'
    <process Name="Mike" id="3" />'n'
</processes>'n'
<tasks  color="" alpha="" font="" fontColor="" fontSize="" isAnimated="1">'n'
    <task name="North" processId="1" start="3/1/2005" end="4/2/2005" Id="1_1" color="e1f5ff" borderColor="AFD8F8"/>'n'
    <task name="East" processId="1" start="6/2/2005" end="24/3/2005" Id="1_2" color="e1f5ff" borderColor="AFD8F8"/>'n'
    <task name="Vacation" processId="1" start="25/3/2005" end="18/4/2005" Id="1_3" color="e1f5ff" borderColor="AFD8F8" height="2" showBorder="1" topPadding="49%"/>'n'
    <task name="South" processId="1" start="18/4/2005" end="24/5/2005" Id="1_4" color="e1f5ff" borderColor="AFD8F8"/>'n'
    <task name="South" processId="2" start="15/1/2005" end="5/3/2005" Id="2_1" color="F6BD0F" borderColor="F6BD0F"/>'n'
    <task name="West" processId="2" start="21/3/2005" end="10/5/2005" Id="2_2" color="F6BD0F" borderColor="F6BD0F"/>'n'
    <task name="Global" processId="3" start="7/1/2005" end="26/5/2005" Id="3_1" width="12" color="8BBA00" borderColor="8BBA00"/>'n'
    <task name="South" processId="4" start="13/3/2005" end="19/4/2005" Id="4_1" width="12" color="FF654F" borderColor="FF654F" />'n'
</tasks>'n'
'n'
</chart>';

然后，当我尝试用简单的（echo）回显我的变量时，我得到：

''n''''n''n''n''n''''n

当我使用打印时

echo nl2br(htmlentities($temp));

然后我正确地得到了所有的数据现在，我正试图将这个变量传递到java脚本中，如下所示：

var php_var = "<?php echo $temp; ?>";

但这里传递的值是：

''n''''n''n''n''n''''n

有传递真实数据的想法吗？

您可以使用json_encode将PHP字符串（或数组/对象）安全地重写为javascript:

<script>
    var php_var = <?php echo json_encode($temp); ?>
</script>

json_encode将放置开始和结束的

除此之外：不要在用单引号打开的PHP字符串中使用，这只适用于双引号（"）。
