PHP中错误处理的一些方法
已经玩php一段时间了,基本是from0开始的,经常出现的问题也很多,慢慢的可以熟练的查询文档了,而且,经验也不是很多。
先lookhere。:
error_reporting(1048);//1,2,4,7,...,1048
ob_start();
session_start();
date_default_timezone_set('Asia/Shanghai');
php的递给调用会吃掉很多的内存。
一般的,不要太多的使用define。
在类的构造和属性器方面,5已经做了很多的工作,克服的bug就不说了,__系列的函数都有一些看点,也是支持static的。
按照我现在的写过的程序,很少用到框架页面的,我感觉在php里面速度不在是一个问题。
注意类的调用次序,特别是已经extends的,准确的释放掉内存。
@mysql_fetch_array($result,MYSQL_ASSOC);
这个注意使用乱用,MYSQL_ASSOC,MYSQL_NUM和MYSQL_BOTH是一个enum吧。默认的是MYSQL_BOTH.
mysql的语句,如果执行in的话不再支持limit。so...很麻烦。
支持distinct,group之,程序循环执行,md。
if(get_magic_quotes_gpc()){
$_GET= stripslashes_gpc($_GET);
$_POST= stripslashes_gpc($_POST);
$_COOKIE= stripslashes_gpc($_COOKIE);
}
set_magic_quotes_runtime(0);#magic_quotes_runtime
functionstripslashes_gpc($array){
while(list($key,$value)=each($array)){
if(is_string($value)){
$array[$key]=addslashes(stripslashes($value));
}elseif(is_array($value)) {
$array[$key]=stripslashes_gpc($value);
}
}
return$array;
}

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Building an SQL database involves 10 steps: selecting DBMS; installing DBMS; creating a database; creating a table; inserting data; retrieving data; updating data; deleting data; managing users; backing up the database.
