phplib中常用的方法有set_file,set_block,set_var,parse,ppasre,p,get等。
语法介绍:
phplib中常用的方法有set_file,set_block,set_var,parse,ppasre,p,get等。
声明:由于本系统采用的是phplib,如果页面中有大括号对,这将会替换成空白,所以在写此文章时,用"[[","]]"来替代大括号。大家在用的时候是用大括号便是,此处仅为写文章方便而作此约定。
set_file:是用来引入模板文件。
用法:
代码如下:
$t->set_file("show_main","main.htm");
或
$t->set_file(array(
"show_header"=>"header.htm",
"show_main"=>"main.htm"
));
set_block:用来声明一个区块
用法:
$t->set_block("show_main","rowlist","RL");
稍微解释一下,show_main是用set_file取得的文件句柄,rowlist是模板页面中的区域标识一般如下方式来写
代码如下:
[[param]] |
如上是将
区块是可以嵌套的
代码如下:
[[param]] |
如上所示,这声明一个嵌套区块,这在boeiBlog的像册部分采用了这种方式,有兴趣的朋友可以找出来看看
对于嵌套的模板,我们可以这样来使用
$t->set_block("show_main","rowlist","RL"); // 里面的参数从前向后依次是包含的关系,最后一个是别名,主要用来区块识别
$t->set_block("rowlist","collist","CL"); // 第一个参数是外层块的名称,第二个是自己的名乐,第三个是别名
循环这样的区块时要特别注意
如下:
代码如下:
$t->set_block("show_main","rowlist","RL");
$t->set_block("rowlist","collist","CL");
for($i=0;$i {
$t->set("CL");// 这里要对追加的列循环执行一次清理,否则会多出一堆东西
for($ii=0;$ii {
$t->set_var("param","boeiBlog");
$t->parse("CL","collist",true);// true参数表明这是追加
}
$t->parse("RL","rowlist",true);// 这里的true也是表追加
}
上述代码将会产生一个5X5的表格,每个单元格里会出现一个boeiBlog
set_var:用来作变量替换
上述代码里的$t->set_var("param","boeiBlog");就是把模板中的param变量替换成boeiBlog这个字符串,当然也可以替换成变量,如:
代码如下:
$curdate = date("Y-m-d");
$t->set_var("param",$curdate);
set_var也有追加属性,如:
代码如下:
$curdate = date("Y-m-d");
for($i=0;$i {
$t->set_var("param","
".$curdate,true);
}
这将产生十个连续的当前日期
有时候可以用set_var的追加属性来替代block的循环.
set_var是可以用数组的,如:
代码如下:
$t->set_var(array(
"param"=>"boeiBlog",
"title"=>"柏艾网络"
));
模板如下:
代码如下:
[[param]],[[title]] |
parse:用于解析文件
当我们将模板中的所有变量都处理完之后,可以用parse一将这个模板进行解析。这是模板处理的最后几道工序。
如:
代码如下:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
我们所用的模板可能是:
代码如下:
main.htm
[[param]] |
如果此时还有另外一个模板,其结构如下:
index.htm
那么上述代码将会把main.htm中的变量替换成boeiBlog后再放到index.htm中的main处,最后形成一个在标签中的表格
解析完成之后便是输出页面,
p:用于输出页面
如:
代码如下:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->parse("index","show_index");
$t->p("index");// 此处便会将整个index页面输出,注意main.htm已经被嵌入到index.htm,所以不用$t->p("main");
pparse:同p一样也用来输出页面
如:
代码如下:
上述代码可以如下简化
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->pparse("index","show_index");// 此处将p和parse结合到一起,立即完成解析并输出
get:用于获得文件内容
如:
代码如下:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->parse("index","show_index");
$getstr = $t->get("index");
echo $getstr;// 你将会看到这实际上和p是一样的。
利用get,我们可以轻松的取得生成页面的内容,这可以用于静态页面的生成。可以看到phplib用来处理静态页面是非常方便的

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
