[RESOLVED] Test for simplexml_load_file() support?

[solitario]

/* INITIALIZE THE XML FILE */
	$xml_file=@simplexml_load_file('path/to/my/file.txt');
/* PERFORM AN ERROR TEST */
	if($xml_file) {
		/* LOOP THROUGH THE XML */
			foreach($xml_file->xml_tag AS $tag) {
				/* THE ARRAY */
					// here i fill the array elements
				/* INCREMENT THE VARIABLE */
					$i+=1;
			}
	} else {
		// my alternate code
		// parse it another way...
	}

Hello all.
Is there a way of determining whether or not a server supports simplexml, and if it does not, then go to my alternate code?
Thanks in advance.

A call to undefined function always throws a fatal error in PHP. Fatal errors cannot be caught so your best option is to test it exists first. Use the extension_loaded / function_exists function:

if (extension_loaded("simplexml")) {

}

// OR

If (function_exists("simplexml_load_file")) {
} 

Also, if you are using PHP 4 simple XML will not be available you can test this with the phpversion function too. The simplest way is - function_exists.
