[RESOLVED] Test for simplexml_load_file() support?

Code:

---

/* 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:

PHP Code:

---

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.

Beautiful. Thanks again VisualAd.
