Some MySQL functions in PHP
MySQL can be connected to the web through PHP in two ways, one is through PHP’s MySQL related functions, the related functions are as follows:
MYSQL function
mysql_affected_rows: Get the number of columns affected by the last MySQL operation.
mysql_close: Close the MySQL server connection.
mysql_connect: Open the MySQL server connection.
mysql_create_db: Create a new MySQL database.
mysql_data_seek: Move the internal return indicator.
mysql_db_query: Send query string (query) to the MySQL database.
mysql_drop_db: Remove the database.
mysql_errno: Return error message code.
mysql_error: Return error message.
mysql_fetch_array: Return array data.
mysql_fetch_field: Get field information.
Mysql_fetch_lengths: Returns the maximum length of each column of data in a single column.
mysql_fetch_object: Return object data.
mysql_fetch_row: Returns each column of a single column.
mysql_field_name: Returns the name of the specified field.
mysql_field_seek: Set the indicator to a field of the returned value.
mysql_field_table: Get the name of the data table (table) of the current field.
mysql_field_type: Get the type of the current field.
mysql_field_flags: Get the flags of the current field.
mysql_field_len: Get the length of the current field.
mysql_free_result: Release the occupied memory passed back.
mysql_insert_id: Returns the ID of the last INSERT instruction used.
mysql_list_fields: List the fields of the specified data table.
Mysql_list_dbs: Lists the databases available on the MySQL server.
mysql_list_tables: List the tables (tables) of the specified database.
mysql_num_fields: Get the number of fields returned.
Mysql_num_rows: Get the number of columns returned.
Mysql_pconnect: Enable long-term connection to the MySQL server.
mysql_query: Send a query string.
mysql_result: Get the result of the query.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

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),
