PHP shows deprecated:assigning The return value of the ' new by reference was deprecated in solution

When you imported Excel content to the database with Spreadsheet_excel_reader last night, the following prompts appear:

Deprecated:assigning The return value of new by reference is deprecated in

Navigate to the line that went wrong:

[PHP] View plaincopyprint?

$this->_ole =& New Oleread ();

My local environment is made of php/5.3.3.

Solution: php5.3 started, abolished the "=&" symbol in PHP, so want to copy, directly with = reference can. Details are as follows:

1, PHP5 object replication is the use of the way of reference;

2. If you do not use the reference method, you need to add the keyword clone when copying the object;

3, if in the process of copying, at the same time to change some attributes, then increase the function _clone ();
