A snapshot of a Web page that generates picture formats based on LINNUX+PHANTOMJS _php

Install extensions:
(1) The following is my Linux installation process, if not installed Git, please first yum install git
Installing CASPERJS

The code is as follows:

CD/
git clone git://github.com/n1k0/casperjs.git
CD Casperjs
LN-SF/CASPERJS/BIN/CASPERJS/USR/LOCAL/BIN/CASPERJS//Can ignore the actual execution of PHP is performed/casperjs/bin/casperjs

(2) Install PHANTOMJS, download address: http://phantomjs.org/download.html
After downloading the operation is very simple, directly to the decompression \BIN\PHANTOMJS moved to the \USR\LOCAL\BIN\PHANTOMJS on the right. \
Test PHANTOMJS--version Results without error, indicating installation OK

(3) Install fonts
1. First obtain a set of "Microsoft Ya Black" Font library (Google a lot), including two files Msyh.ttf (normal), Msyhbd.ttf (bold);
2. Create a subdirectory in the/usr/share/fonts directory, such as win, with the following command:

The code is as follows:

# Mkdir/usr/share/fonts/win

3. Copy Msyh.ttf and Msyhbd.ttf to this directory, for example, these two files are placed under/root/desktop, using the command:

The code is as follows:

# Cd/root/desktop
# CP Msyh.ttf msyhbd.ttf/usr/share/fonts/win/

4. Create font index information and update font cache:

The code is as follows:

# Cd/usr/share/fonts/win
# Mkfontscale (if prompted Mkfontscale:command not found, you need to install it yourself # Yum install Mkfontscale)
# Mkfontdir
# Fc-cache (if prompted Fc-cache:command not found, you need to install # Yum installs Fontconfig)

At this point, the font has been installed!

<?php   if (isset ($_get[' url ')))   {     set_time_limit (0);       $url = Trim ($_get[' url ');     $filePath = MD5 ($url). PNG ';     if (Is_file ($filePath))     {       exit ($filePath);     }      If you do not add this sentence will be an error "Fatal: [Errno 2] No such file or directory; Did you install PHANTOMJS? ", details refer to http://mengkang.net/87.html    putenv (" phantomjs_executable=/usr/local/bin/ Phantomjs ");    $command = "Phantomjs phantomjs.js {$url} {$filePath}";     @exec ($command);       Exit ($filePath);   } ?>

var page = require (' webpage '). Create (); var args = require (' system '). Args;  var url = args[1]; var filename = args[2];  Page.open (URL, function () {   page.render (filename);   Phantom.exit (); });
