PHP error: deprecated: assigning the return value of new by reference is deprecated in

PHP of many friendsProgramAfter the PHP version is upgraded to 5.3, "deprecated: assigning the returnvalue of New by reference is deprecatedin" will appear. This is because after 5.3, the "= &" symbol cannot be used. You can simply use "=.

So there are two solutions to this problem:

1. Downgrade PHP to Version 5.3 or lower, but it is not a wise choice to move back.

2. replace all the "= &" symbols in the program with "=.

When I used spreadsheet_excel_reader to import the Excel content to the Database last night, the following prompt was displayed:

Deprecated: assigning the return value of new by reference isdeprecated in

Locate the line with the error:

1$ This-> _ Ole = & New oleread ();

My local environment uses PHP/5.3.3.

The following passage is referenced by thinking

Solution: After php5.3 starts, the "= &" symbol in PHP is abolished. to copy the file, use = to reference it directly. The details are as follows:

1. PhP5 object replication adopts the reference method;
2. If the reference method is not used, add the keyword clone when copying the object;
3. If you want to change some attributes during the replication process, add function _ clone ();
