how to make php scripts executable instead of downloadable using nginx - php

Question

Recently I set up a virtual machine through vagrant and I'm using nginx as a web server. The OS I'm using for the VM is Ubuntu Linux 12.04. The problem is that any script I write in PHP gets downloaded, instead of being executed on the browser. Seeing as the PHP interpreter is normally installed I figured I'd post here the config file of nginx, as this is where the problem is likely to be found. Being a novice in the world of web development, I can't figure out what is out of the ordinary, can you guys take a look and tell me if you see something wrong? Thanks.
server {
listen 80;
server_name localhost;
root /vagrant/www/web;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
#strip app.php/ prefix if it is present
rewrite ^/app\.php/?(.*)$ /$1 permanent;
location / {
index app.php;
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
# pass the PHP scripts to FastCGI server listening socket
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_pass unix://var/run/php5-fpm.sock;
fastcgi_keep_conn on;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
# enable global phpMyAdmin
location /phpmyadmin {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/phpmyadmin/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
fastcgi_pass unix://var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /phpMyAdmin {
rewrite ^/* /phpmyadmin last;
}
}

Answer 1

Looks like you're having double // to indicate the fastcgi_pass path of php in your location block, try this instead
location ~ \.php$ {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_keep_conn on;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}

Answer 2

As was my suspicion the problem was in this location block:
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_pass unix://var/run/php5-fpm.sock;
fastcgi_keep_conn on;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
The parameter to the location directive is a regular expression that defines only two possible file names: app.php and app_dev.php, thus making any other filename non-executable. For this to change, one needs to either add the names of one's php scripts to the parameter or change the regular expression to a more inclusive form as per Frederic Henri's suggestion.
