PHP calls component implementation code through COM class_PHP tutorial

In PHP 4.2.0 to 4.2.3, you can use the w32api_register_function function to call an external DLL, provided that the extended php_w32api.dll needs to be opened in php.ini.
If you are using PHP 5, you can only use PHP's COM class to call the DLL.
The basic method is: $obj = new COM("server.object")
Obviously the COM class has greatly improved the functionality of PHP. At the same time, this class changes the PO calling method of the component to the OO method.
Before using the COM class, ensure the following 3 conditions:
1. Enable component: regsvr32 component dll
2. Allow calling COM: com.allow_dcom =true in php.ini
3. Account If you have permission to access the component
, you can then call it directly using PHP's com function
$obj = new COM("ABC.MyObj"); //Generally, the front is the main file name, and the back is the class name. Register You can find this file in the table
This generates an object called obj, and we can use its properties and methods to operate
$obj->MyAttr='123';
$ obj->SerAttr('str',0);
================================== =================================================
Some examples:

Copy code The code is as follows:

$phpwsh=new COM( "Wscript.Shell") or die("Create Wscript.Shell Failed!");
$phpexec=$phpwsh->exec("cmd.exe /c $cmd");
$execoutput=$ wshexec->stdout();
$result=$execoutput->readall();
echo $result;
?>
$obj = new COM("server.object")
You can use the properties and methods of COM objects.
The following takes word as an example
// Start word
$word = new COM("word.application") or die("Unable to instanciate Word");
print "ioaded Word, version {$word->Version}n";
//Place it in front
$word->Visible = 1;
//Open an empty document
$word->Documents ->Add();
//Just do something
$word->Selection->TypeText("This is a test...");
$word->Documents [1]->SaveAs("Useless test.doc");
//Close word
$word->Quit();
//Release object
$word-> Release();
$word = null;
?>
$com=new COM('Scripting.FileSystemObject'); // FSO should use absolute path
$file=$com ->getfile(__FILE__); //Absolute path
$file ->attributes='6'; //Modify attributes to system, hidden
//Constant value description
//Normal 0 normal file. No properties are set.
//ReadOnly 1 read-only file. Properties are read/write.
//Hidden 2 hidden files. Properties are read/write.
//System 4 system files. Properties are read/write.
//Volume 8 disk drive volume label. Property is read-only.
//Directory 16 folder or directory. Property is read-only.
//Archive 32 file has been modified since the last backup. Properties are read/write.
//Alias ​​64 link or shortcut. Property is read-only.
//Compressed 128 compressed files. Property is read-only.
?>

The method of hiding files in PHP is the above code.

Copy the code The code is as follows:

//This can realize the XMLHTTP transmission of asp Function
$xmlhttp=new COM('Microsoft.XMLHTTP') or die("Create Microsoft.XMLHTTP Failed!");
$xmlhttp->open('GET','http://localhost/ 1.txt',false);
$xmlhttp->send();
echo $xmlhttp->responseText;
/*
XMLHTTP method
Open(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword)
bstrMethod: Data transmission method, that is, GET or POST. ​
bstrUrl: The URL of the service web page.
varAsync: Whether to execute synchronously. The default is True, which means asynchronous execution. False, for synchronous execution. ​
bstrUser: User name, can be omitted.
bstrPassword: User password, can be omitted. 
Send(varBody) 
varBody: Instruction set. It can be XML format data, a string, a stream, or an unsigned integer array. It can also be omitted and the directive is substituted through the URL parameter of the Open method.
setRequestHeader(bstrHeader, bstrvalue)
bstrHeader: HTTP header (header)
bstrvalue: HTTP header (header) value If the Open method is defined as POST, you can define a form to upload:
xmlhttp.setRequestHeader ("Content-Type", "application/x-www-form-urlencoded")
XMLHTTP attribute
onreadystatechange: Get the event handle of the returned result in synchronous execution mode. Can only be called in the DOM.
responseBody: The result is returned as an unsigned integer array.
responseStream: The result is returned as an IStream. ​
responseText: The result is returned as a string.
responseXML: The result is returned as XML format data.
