Technically ...
If you had the same OS as the Server and Built PHP5 from Source and then copied all the Libraries reqiuired and uploaded them...
you could write a work around Shell Script to run PHP5 from your own Space and possible use
.htaccess[/] to run it as if it were a CGI binary (I believe) I maybe wrong.
php5 (chmod 777)
#!/bin/sh
cd /files/homeX/username/cgi-bin/php5 #perhapse /share/storeage/XX/un/username/cgi-bin/php5 where (un) == 1st 2 letters of username
export @LD_LIBRARY_PATH="./libs/"
./php5.bin
I would read thorugh the "install" Script. somewhere it is bound to use the function "
phpversion()" with an if statment following:
$PHPVersion = phpversion(); //format Major.Minor.Revision
$PHPVer = explode('.',$PHPVersion);
$PHPVerMajor = $PHPVer[0];
$PHPVerMinor = $PHPVer[1];
$PHPVerRevision = $PHPVer[0];
if($PHPVerMajor == 5){
...
}
Null this section of code using Multi-line /* */ Comment like so.
/*
$PHPVersion = phpversion(); //format Major.Minor.Revision
$PHPVer = explode('.',$PHPVersion);
$PHPVerMajor = $PHPVer[0];
$PHPVerMinor = $PHPVer[1];
$PHPVerRevision = $PHPVer[0];
if($PHPVerMajor == 5){
...
}*/
Otherwise, I would seek a previous version of the package which works with PHP4 and secure it to the maximum.
If that previous version doesn't have the functionality you were after,
I would seek any Change Log files of PHP which relate to compatability of functions and just check through the source. (hours of work)
To be honest I wouldn't know any differences between PHP4 and PHP5, as such in terms of the Core code and functionality that would affect the majority scripts from working as they would on PHP4 even though they specifiy PHP5...
The only functions which I would have thought would change are entirely specific
optional modules such as
GD,
MySQL etc...
Hope that was of some help!
Jim,
