solution to installation of expect module in php5

following message will come if php expect module didn't find on web server expect example page.

fopen(): Unable to find the wrapper "expect" - did you forget to enable it when you configured PHP?

This means expect.so is not there in /usr/lib/php5/extensions

to install expect module  follow streps :


1.   Before installation install dependencies  : expect-devel, tcl-devel packages

2. run following command to build and install expect module

pecl install channel://pecl.php.net/expect-0.3.1

It will create /usr/lib/php5/extensions/expect.so file

3. Now add config file for php in /etc/php5/conf.d/expect.ini

cat > /etc/php5/conf.d/expect.ini  << END
; comment out next line to disable mysqli extension in php
extension=expect.so

END

4. Now check php modules  by following command:

php -m   

 If you get following error  :

1   /usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: cannot find -lexpect
/usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: cannot find -ltcl
collect2: error: ld returned 1 exit status
make: *** [expect.la] Error 1
ERROR: `make' failed

for that  go to /usr/lib/ 

ln -s libexpect<version>.so  libexpect.so

ln -s libtcl<version>.so libtcl.so

Nginx Error - 413 Request Entity Too Large

Hi if you get 413 Request Entity Too Large error in Nginx Serve to avoid this error some people suggest increase post size in php.ini ie
post_max_size = 25M
But even changing this value error still occurring means you need to change nginx configuration file.
add client_max_body_size 20M to nginx configuration file of server. check below where to add that line.

server {
    client_max_body_size 20M;
    listen 80;
    server_name example.com;
    access_log /var/log/nginx/nginx.access.log;
    error_log /var/log/nginx/nginx.error.log;
....
....
}
