Jul 25, 2025 pm 05:39 PMTo build a PHP environment with a Mac and support SQLite, the key is to configure the PHP environment and enable SQLite extensions. 1. Check whether PHP is installed. If it is not installed, use Homebrew to run brew install php for installation; 2. Find the php.ini file path, edit the file, and enable pdo_sqlite and sqlite3 extensions; 3. Restart the Apache or Nginx server to make the configuration take effect; 4. Create a test file test.php, and use PDO to connect to the SQLite database to verify whether the extension is enabled successfully; 5. Use the phpinfo() function to further confirm whether the SQLite extension is loaded correctly; 6. If the connection fails, check whether the extension configuration, database path, permissions, files exist and PHP version problems; 7. Use Homebrew to install the sqlite3 command line tool, run sqlite3 on the terminal to operate the database, and execute SQL commands such as library construction, table construction, modification and query. The above steps can be operated in sequence to complete the environment and support SQLite.
It is actually not difficult to build a PHP environment with a Mac and support SQLite. The key is to clarify your ideas and take them step by step. The core is to configure the PHP environment and then make sure that the SQLite extension is enabled correctly.

Solution
-
Check if PHP is installed: Open the terminal and enter
php -v
. If PHP version information is displayed, it means it has been installed. If not, you need to install PHP first. You can use Homebrew to install, the commandbrew install php
. -
Install Homebrew (if not installed): If you don't have Homebrew on your Mac, install it first. Run the following command in the terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
During the installation process, you will be prompted to enter your password and follow the prompts.
Install PHP: Run
brew install php
. Homebrew will automatically install the latest version of PHP.Verify PHP installation: Run
php -v
again to confirm that PHP has been successfully installed and display version information.Find
php.ini
file: PHP configuration information is in thephp.ini
file. Runphp --ini
to find the loaded configuration file path. Usually located in/usr/local/etc/php/版本號/php.ini
.Enable SQLite extension: Open the
php.ini
file, you can use any text editor. Search for;extension=pdo_sqlite
and;extension=sqlite3
. Remove the semicolon in front of each line;
, uncomment, enable both extensions. Save the file. If these two lines are not found, manually addextension=pdo_sqlite
andextension=sqlite3
to the file.Restart the Apache server (if using Apache): If you use Apache as the web server, you need to restart it for the configuration to take effect. Run
sudo apachectl restart
in the terminal. If you are using another web server, such as Nginx, please restart as appropriate.-
Test SQLite connection: Create a simple PHP file, such as
test.php
, and place it in the root directory of your web server. The file contents are as follows:<?php try { $db = new PDO('sqlite:test.db'); echo "SQLite connection succeeded!"; } catch (PDOException $e) { echo "SQLite connection failed: " . $e->getMessage(); } ?>
Visit
http://localhost/test.php
in your browser. If "SQLite connection is successful!" is displayed, the SQLite extension has been enabled successfully. If the error message is displayed, double check the configuration in thephp.ini
file and make sure the SQLite database filetest.db
exists and the web server has permission to access.
How to confirm whether the SQLite PHP extension is successfully enabled?
In addition to the above test connection method, you can also view it through phpinfo()
function. Create a PHP file with the following content:
<?php phpinfo(); ?>
Open this file in your browser. Search for the "SQLite" or "PDO" section. If relevant information is found, the SQLite extension has been successfully enabled. If not found, check the configuration in the php.ini
file again and restart the web server. Sometimes, it may be necessary to completely shut down and restart your web server for the configuration to take effect.
Why can't my PHP program connect to SQLite database?
This is usually a few reasons:
- SQLite extension not enabled: Make sure
pdo_sqlite
andsqlite3
extensions are enabled in thephp.ini
file. - Database file path error: Check whether the database file path specified in your PHP code is correct. The path can be a relative path or an absolute path. The relative path is the path relative to the PHP script.
- Permissions Issue: The web server may not have permission to access the database file. Ensure that web server users (such as
www-data
orapache
) have permission to read and write database files. You can use thechmod
command to change file permissions. - The database file does not exist: make sure the database file does exist. If the database file does not exist, PDO will automatically create it, but only if the web server has permission to create the file.
- PHP version issue: Some older versions of PHP may have compatibility issues with SQLite extensions. Try upgrading to the latest version of PHP.
How to use SQLite in the command line?
In addition to using SQLite in PHP programs, you can also use it on the command line. First, you need to install the SQLite command line tool. On a Mac, you can use Homebrew to install: brew install sqlite3
.
After the installation is completed, you can use the sqlite3
command to operate the database. For example, to create a database called mydatabase.db
, you can run sqlite3 mydatabase.db
. This will open the SQLite command line interface.
In the command line interface, you can execute various SQL commands such as CREATE TABLE
, INSERT
, SELECT
, UPDATE
and DELETE
. For example, to create a table called users
, you can run:
CREATE TABLE users ( id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, email TEXT );
To insert a record, you can run:
INSERT INTO users (name, email) VALUES ('John Doe', 'john.doe@example.com');
To query all records, you can run:
SELECT * FROM users;
To exit the SQLite command line interface, you can enter .exit
.
