[英]Defining Variables or constant in XMLwriter PHP
i am new in PHP. 我是PHP新手。 Using xmlwriter to produce an xml file.
使用xmlwriter生成xml文件。 I have below code.
我有下面的代码。
$xml = new XMLWriter();
$xml->openURI('test.xml');
$xml->setIndent(true);
$mmmid = '1981';
$xml->startDocument('1.0', 'UTF-8');
$xml->text('<raml xmlns="raml21.xsd" version="2.1">');
$xml->text(' <cmData scope="all" type="plan">');
$xml->text(' <header>');
$xml->text(' <log dateTime="2012-11-05T12:27:50+02:00" appInfo="Manager" user="WebUI" appVersion="4.5133.90" action="created"/>');
$xml->text(' </header>');
$xml->text(' <managedObject class="MRBTS" distName="IDENTITY-'$mmmid'" operation="create" version="1803">');
$xml->text(' <p name="btsName">B1123</p>');
$xml->text(' </managedObject>');
I want to define the mmmid in the output of xml file, so it will be appeared in the output distName="IDENTITY-1981" 我想在xml文件的输出中定义mmmid,因此它将出现在输出distName =“ IDENTITY-1981”中
How can i define variable mmmid in the code and expected printed in output of the text above? 如何在代码中定义变量mmmid并在上面的文本输出中预期打印?
Thank you a lot, Br,FM 非常感谢Br,FM
That would be it: 就是这样:
$xml->text(' <managedObject class="MRBTS" distName="IDENTITY-' . $mmmid . '" operation="create" version="1803">');
You concatinate strings in PHP via the .
您可以通过来在PHP中添加字符串
.
operator, see the PHP manual on strings 操作符,请参见有关字符串的PHP手册
When concatenating a variable with strings in PHP there are several ways of doing it. 在PHP中将变量与字符串连接时,有几种方法可以实现。
"
as surrounding delimiters "
作为分隔符 When using double quotes "
in PHP you can use variables inside the string as usual 在PHP中使用双引号
"
,您可以照常在字符串内使用变量
$foo = 4;
echo "Hello $foo";
Output : 输出 :
Hello 4
This would give the following solution for your problem: 这将为您的问题提供以下解决方案:
# Note that you need to escape the original double quotes with a backslash
$xml->text("<managedObject distName=\"IDENTITY-$mmmid\" operation=\"create\" version=\"1803\">');
.
.
Another way of binding a variable with text is by using a dot .
将变量与文本绑定的另一种方法是使用点
.
between the variable and string (this also works with only strings or only variables as well). 在变量和字符串之间(这也仅适用于字符串或仅适用于变量)。 For this method you can use either single
'
or double quotes "
. 对于这种方法,你可以使用单
'
或双引号"
。
$foo = 4;
echo 'Hello ' . $foo;
Output 产量
Hello 4
And with this method it would give you this 使用这种方法,它将为您提供
$xml->text('<managedObject distName="IDENTITY-' . $mmmid . '" operation="create" version="1803">');
