PHP MEMCACHE高级缓存应用详解
Memcache函数库是在 PECL(PHP Extension Community Library)中,主要作用是搭建大容量的内存数据的
临时存放区域,在分布式的时候作用体现的非常明显,否则不建议使用。 本人在ubuntu上安装
完运行的时候报错:
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2:
cannot open shared object file: No such file or directory
按照:《libeven、memcached、libmemcache安装》中的方法,使用:
sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
可以修正这个BUG
通过新得立安装php的memcached模块,注销/etc/php5/conf.d/memcached.ini里面的“;”,重启apache
,调用phpinfo()出现memcached的信息
执行:
$memcache = new Memcache;
$memcache->connect(localhost, 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Servers version: ".$version."
";
?>
$memcache = new Memcache;
$memcache->connect(localhost, 11211) or die ("Could not connect");
print_r($memcache->getStats());
/**

?>
$memcache = new Memcache;
$memcache->connect(localhost, 11211) or die ("Could not connect");
$memcache->set( name, leo, 0, 30);
if(!$memcache->add( name, susan, 0, 30))
{
echo susan is exist;
};
$memcache->replace

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
