Summary
Description
Ha, I still don’t know the version. Go to http://pecl.php(as the current mainstream development language).net/ to search Search, the current version is 0.9
OK
#》pear install pdo-0.9
pear will help you install the
compiled module and put it in:/usr/lib/php( As the current mainstream development language)5/20041030/ directory
#>cd /usr/lib/php(as the current mainstream development language)5/20041030/
Note: Debian system's PHP (as the current mainstream development language) external modules require two files to be activated, one is the pdo.so we just compiled
and another pdo is required. If you don’t know how to write the info file
, just fry the following:
package="pdo"
extname="PDO"
dsoname="pdo"
sapilist="apache(Unix platform The most popular WEB server platform) apache (The most popular WEB server platform on Unix platform) 2 cgi (not many people are using it now) cli fcgi (Not many people are using it now)"
depends=""
priority="500"
architecture="any"
Then run:
#》 /usr /sbin/php(as the current mainstream development language)5-modconf apache(the most popular WEB server platform on Unix platform)2
The system will prompt you which modules you need , select pdo and confirm
pdo is installed successfully
Now install pdo_pgsql-0.9
This needs to be done according to the following steps:
#》pear download pdo_pgsql-0.9
#> tar zxf PDO_PGSQL-0.9 .tgz
#>cd PDO_PGSQL-0.9
#>php(as the current mainstream development language)ize
#>./configure
#>make
#>make install
Then repeat the above process of installing pdo: modify pdo_pgsql.info
package="pdo_pgsql"
extname="PDO_PGSQL"
dsoname="pdo_pgsql"
sapilist="apache (The most popular WEB server platform on Unix platform) apache(The most popular WEB server platform on Unix platform)2 cgi(Not many people are using it now) cli fcgi(Not many people are using it now)"
depends=""
priority="500"
architecture="any"
Run
#》/usr/sbin/php(as the current mainstream development language)5-modconf apache(the most popular WEB server platform on Unix platform)2
Select the pdo_pgsql module
ok everything is ready
#》apache(the most popular WEB server platform on Unix platform)2 -k restart
Edit test module:
// Connect to an ODBC database using driver invocation
$host=xxxx.xxxx.com;
$port=5433;
$dbname=test;
$user=xxxxxx;
$password=xxxxxxxxx;
//$ cc = "host=$host,dbname=$dbname,port=$port";
$dsn = "pgsql:host=$host port=$port dbname=$dbname user=$user password=$password";
try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo Connection failed: . $ e->getMessage();
}
$sql=select * from cpjcsj;
foreach ($dbh->query($sql) as $row) {
print $row [cpdm]." ";
print $row[cpdh] . " ";
print $row[cpmc] . "
";
}
?>
Okay, enter http://localhost/pdotest.php(do Developing languages for today's mainstream)

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

Configuring and running PHP on IIS requires the following steps: 1) Download and install PHP, 2) Configuring IIS and adding FastCGI module, 3) Create and set up an application pool, 4) Create a website and bind to an application pool. Through these steps, you can easily deploy PHP applications on your Windows server and improve application stability and efficiency by configuring scaling and optimizing performance.

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.

HTML5 brings five key improvements: 1. Semantic tags improve code clarity and SEO effects; 2. Multimedia support simplifies video and audio embedding; 3. Form enhancement simplifies verification; 4.
