PHP installation guide linux five_PHP tutorial
The installation method of PM package is created by REDHAT company. This installation method makes it extremely easy to install applications. Now many LINUX distribution companies have also added RPM installation methods to their products, so that the installation of RPM packages has become a standard for LINUX program installation.
Before installing the RPM package, we need to be familiar with some of the command forms and parameters of RPM. In the LINUX text interface, enter the following command:
rpm -help
You can see that there are many parameters. Use the following command to display the HELP file in split screen:
rpm -help |more
Among the many parameters of RPM, the most common ones are -e, -ivh, and -ql.
These three commands are to delete installed RPM packages, install RPM packages, and query installed RPM packages. After understanding the use of these three commands, we can install the program.
First, we need to find the installation file, which is the RPM package to be installed. This package can be obtained from many FTP sites, and these RPM packages can also be found in LINUX versions distributed by many companies. Remember, you must ensure your ROOT status before installation. Only the ROOT identity can load hardware, install programs, and other operations. Let's take installing the php-3.0.7.i386.rpm package as an example to explain how to install it. In the command line, type the following command to start the PHP installation:
rpm -ivh php-3.0.7.i386.rpm
You will see a progress bar, which is used to indicate the progress of the installation. When the progress bar reaches the end, php-3.0.7.i386.rpm is installed.
In this RPM package of PHP, because it supports relatively few options, it generally cannot meet our requirements. Then we can also customize and compile PHP (only suitable for users using REDHAT6.1).
The specific steps are as follows:
First obtain the PHP source code package, unzip it and enter the package.
Modify the apxs file in the /usr/sbin/ directory. Change:
my $CFG_LIBEXECDIR =modules; #substituted via APACI install
to:
my $CFG_LIBEXECDIR =/usr/lib/apache; #substituted via APACI install
Check freetype- Whether the devel package is installed? If not, please install it according to the following command:
rpm -I freetype-devel-1.3.6.i386.rpm
Start the configuration. This step can be done by referring to the previously compiled options. The following options are recommended:
./configure--with-apxs=/usr/sbin/apxs--with-mysql--with-ldap--with-config-file-path=/etc/httpd/conf
Then, use the following commands to compile and install the new PHP.
Make
Make install
Copy the php3.ini-dist file in the source file directory to the /etc/httpd/conf directory and rename it to php3.ini. Use the following command to restart the APACHE service.
/etc/rc.d/init.d/httpb tart
At this time, the new PHP version will take effect.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.

The... (splat) operator in PHP is used to unpack function parameters and arrays, improving code simplicity and efficiency. 1) Function parameter unpacking: Pass the array element as a parameter to the function. 2) Array unpacking: Unpack an array into another array or as a function parameter.

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

Strict types in PHP are enabled by adding declare(strict_types=1); at the top of the file. 1) It forces type checking of function parameters and return values to prevent implicit type conversion. 2) Using strict types can improve the reliability and predictability of the code, reduce bugs, and improve maintainability and readability.

Composer is a dependency management tool for PHP. The core steps of using Composer include: 1) Declare dependencies in composer.json, such as "stripe/stripe-php":"^7.0"; 2) Run composerinstall to download and configure dependencies; 3) Manage versions and autoloads through composer.lock and autoload.php. Composer simplifies dependency management and improves project efficiency and maintainability.

There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.
