In daily operation, I believe many people have doubts about how to solve the problem of error report after upgrading php to 5.3 +. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "how to solve the error report after upgrading php to 5.3 +". Next, please follow the editor to study!

Running in a php5.3 environment, there are often

Deprecated: Function ereg () is deprecated in... And Deprecated: Function ereg_replace () is deprecated in... These types of error messages.

The reason for this is that versions above php5.3 do not support the ereg () function, but use the preg_match () function; do not support the ereg_replace () function, but use the preg_replace () function.

Solution: change an unsupported function to a supported function.

For example

The copy code is as follows:

If (eregi ('^ ('value', $value))

Change to:

The copy code is as follows:

If (preg_match ('/ value/', $value)

Another example is:

The copy code is as follows:

$string = ereg_replace ('value','', trim ($string))

Change to:

The copy code is as follows:

$string = preg_replace ('{value}',', trim ($string))

Resolve Deprecated: Assigning the return value of new by reference is deprecated in error report

Because we are now php 5.3, we can use "=" directly in php5.3, whereas previously we used the "= &" symbol in php environments where local tests were less than 5.3.

The "= &" symbol is no longer allowed in programs after version 5.3. If your website has a Deprecated: Assigning the return value of new by reference is deprecated in error, don't worry, locate the wrong file first, find out if "= &" is used in the program, and find that the "= &" symbol is used. after removing the'& 'symbol, the program works fine.

Question: Deprecated: Function set_magic_quotes_runtime () is deprecated in

The reason for this prompt is that this feature (set_magic_quotes_runtime ()) has been turned off after PHP5.3.

And this feature has been completely removed from PHP6.

You can comment or delete the wrong line, or add the @ symbol before set_magic_quotes_runtime ()

At this point, the study on "how to solve the error report after upgrading php to 5.3 +" is over. I hope to be able to solve your doubts.
