Rename the split() function to explode() function.
That will solve it.

Few month ago, while upgrading my blog,i have came across with this error message.

You can implement it to other script that generate same error message.

Ugly fix for ‘ereg () is deprecated error.’

While installing my php script last night, i have came across with this error message.Most probably you have installed PHP 5.3 or upper version.If you upgraded to PHP 5.3, chances are high you’re going to run into a few warnings or deprecated function messages.
An example is the ereg family of functions, which are gone for good, as they were slower and felt less familiar than the alternative Perl-compatible preg family.

To migrate ereg():

ereg('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/', $this->file_src_name, $extension);

Notice that I wrapped the pattern (\.([^\.]*$)) around / /, which are RegExp delimiters. If you find yourself escaping / too much (for an URL for example), you might want to use the # delimiter instead.

To migrate ereg_replace():

$this->file_dst_name_body = ereg_replace('[^A-Za-z0-9_]', '', $this->file_dst_name_body);

becomes

$this->file_dst_name_body = preg_replace('/[^A-Za-z0-9_]/', '', $this->file_dst_name_body);

Again, I just added delimiters to the pattern.
If you are using eregi functions (which are the case-insensitive version of ereg), you’ll notice there’re no equivalent pregi functions. This is because this functionality is handled by RegExp modifiers.

Basically, to make the pattern match characters in a case-insensitive way, append i after the delimiter:

eregi('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/i', $this->file_src_name, $extension);
