Regex Sed command replacement

Question

In my php.ini I have

error_reporting = E_ALL

I want to change it to

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

with sed command

sed -i "s/^error_reporting = .*/error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT/" /etc/php5/apache2/php.ini

I get a different result:

error_reporting = E_ALL error_reporting = E_ALL ~E_DEPRECATED error_reporting = E_ALL ~E_STRICT

but it should be

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

BTW, the sed command is in the bash script.

&

has special meaning in the sed command's replacement entry s

; it is replaced with the matching string. You should avoid this:

sed -i 's/^error_reporting = .*/error_reporting = E_ALL \& ~E_DEPRECATED \& ~E_STRICT/' /etc/php5/apache2/php.ini
