Function ereg_replace() is deprecated - How to clear this bug? [duplicate]

I have written following PHP code:

$input="menu=1&type=0&";

print $input."<hr>".ereg_replace('/&/', ':::', $input);

After running above code, it gives following warning,

Deprecated: Function ereg_replace() is deprecated

How can I resolve this warning.

Solution 1:

Switch to preg_replace^Docs and update the expression to use preg syntax (PCRE) instead of ereg syntax (POSIX) where there are differences^Docs (just as it says to do in the manual for ereg_replace^Docs).

Solution 2:

print $input."<hr>".ereg_replace('/&/', ':::', $input);

becomes

print $input."<hr>".preg_replace('/&/', ':::', $input);

More example :

$mytext = ereg_replace('[^A-Za-z0-9_]', '', $mytext );

is changed to

$mytext = preg_replace('/[^A-Za-z0-9_]/', '', $mytext );

Solution 3:

change the call to ereg_replace to use preg_replace instead
