Temp downgrading of PHP version.

The situation I find myself in right now is that my home (read: development)
machine has PHP5 installed but my target machine (read: production) only has
version 4 installed. This has caused a couple of problems with testing
passing my code but the production machine failing. (one example is the
str_ireplace() function). I have been doing testing for the existence of a
function but I first have to know if it is exclusive to version 5 whether or
not it is necessary. Is there a flag I can set on my local machine to
temporarily downgrade my version so that I will have the same limitations as
the host machine?

Thanks,
Don Freeman

There is no flag, but you could install both versions and, when using
Apache, toggle modules in your httpd.conf file:

# PHP4 enabled
LoadModule php4_module modules/mod_php4.so
#LoadModule php5_module modules/mod_php5.so

# PHP5 enabled
#LoadModule php4_module modules/mod_php4.so
LoadModule php5_module modules/mod_php5.so

Also a PHPINIDir directive is useful, as you'll likely have a slightly
different config between the two versions, such as different loadable modules.
Probably more relevant on Windows, though - you'll need a different
extension_dir. On Unix there's more of a tendency to compile the extensions
statically into PHP.

Perhaps could do a batch conversion using Alan's
