I know that PHP is a powerful tool for making dynamic and interactive Web pages. So I am making some practice in PHP. Recently I have started the PHP, so I don't have an enough knowledge. I have come through libxml Functions. Can anyone explain me what are the PHP libxml Functions.? If possible give me some attributes or an examples. Please provide me some useful information. Any positive information about the topic are warmly welcomed..!!

As you said that PHP is a powerful tool for making dynamic and interactive Web pages. It is also widely-used, free, and efficient alternative to competitors such as Microsoft's ASP. The following are some functions of PHP that the latest version supports :
If you want to Clear libxml error buffer, you can use the function libxml_clear_errors().
If you want to retrieve array of errors, you can use the function libxml_get_errors().
Here is an example for libxml_clear_errors().

<?php
libxml_clear_errors()
?>

This is an example of libxml_get_errors().

<?php
libxml_get_errors()
?>

[void]

The function libxml_get_last_error() is also related to the PHP libxml Functions. If you want to retrieve last error from libxml, you can use the function libxml_get_last_error(). The libxml_get_last_error() returns an error object on success, and FALSE on failure or if there are no errors in the libxml error buffer. Here is an example for that function :

<?php
libxml_get_last_error()
?>

You can use the function libxml_use_internal_errors() for disabling the ibxml errors and allow user to fetch error information as needed. This function is also related with PHP libxml Functions. The libxml_use_internal_errors() function disables standard libxml errors and enables user error handling. Also this function returns the previous value of the use_lib_errors parameter. Here is the example of libxml_use_internal_errors() :

<?php
libxml_use_internal_errors()
?>

I am providing you with some PHP libxml Constants :

• LIBXML_DTDLOAD - Used to Load external subset.
• LIBXML_DTDATTR - Set default DTD attributes.
• LIBXML_NOCDATA - Used to set CDATA as text nodes.
• LIBXML_NOBLANKS - For Removing the blank nodes.
• LIBXML_COMPACT - For setting small nodes allocation optimization. This may improve the application performance.
• LIBXML_DTDVALID - Validate with the DTD.
