How to find out what version of php is running in the console, x32 or x64?

Question

PHP

Both versions of
php-cli.i386 5.3.8-2.el5.art installed
php-cli.x86_64 5.3.8-2.el5.art installed

php -v and php -vv show nothing.

Answer 1

See what exactly is run by the php command with which php. There's probably some kind of link to another link. Follow to the end of the path, at the end there will be a binary on which you need to set file.
For example in debian it looks like this:
$ which php
/usr/bin/php
$ ls -l /usr/bin/php
lrwxrwxrwx 1 root root 21 Jul 9 16:21 /usr/bin/php -> /etc/alternatives/php
$ ls -l /etc/alternatives/php
lrwxrwxrwx 1 root root 13 Jul 9 16:21 /etc/alternatives/php -> /usr/bin/php5
$ file /usr/bin/php5
/usr/bin/php5: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0x39e3f1f9c4293920472b0ab8cc15cc3b1aa88f30, stripped
