Some errors that occur after PHP upgrade to 5.3+, such as Ereg (); Ereg_replace (); Function Error _php Instance

Running in a php5.3 environment often occurs

deprecated:function Ereg () is Deprecated in ... and Deprecated:function ereg_replace () is a deprecated in ... These types of error alerts.

The reason for this is that the php5.3 version does not support the Ereg () function, but instead uses the Preg_match () function; the ereg_replace () function is not supported, and the Preg_replace () function is used.

　　Workaround: Modify the unsupported function to a supported function.

For example

　Copy the Code code as follows:
if (eregi (' ^ (' value '), $value)

Switch

　Copy the Code code as follows:
if (Preg_match ('/value/', $value)

Again for example:

　　Copy the Code code as follows:
$string = ereg_replace (' value ', ' ', Trim ($string));

Switch

Copy the Code code as follows:
$string = Preg_replace (' {value} ', ', trim ($string));

Fix deprecated:assigning The return value of new by reference was deprecated in error

Because we now PHP is 5.3 reason, in the php5.3 can be used directly with "=", and before because the local test is 5.3 below the PHP environment with the "=&" symbol.

The "=&" symbol is not allowed to be used in the program after version 5.3. If your site appears deprecated:assigning the return value of the new by reference was deprecated in error, do not worry, first locate the wrong file, find out if it is used in the program "=& ", found using the" =& "symbol, remove the ' & ' symbol after the program runs normally.

Problem: Deprecated:function set_magic_quotes_runtime () is Deprecated in

The reason for this hint is that this attribute (Set_magic_quotes_runtime ()) has been turned off after PHP5.3.

This feature has been completely removed from the PHP6.

You can comment or delete the line that went wrong, or add the @ sign before set_magic_quotes_runtime ()
