How to set up a php environment locally in win7 (detailed steps)

When developing web applications or websites, we often use PHP language to process data and logic. So how to set up a PHP development environment on the Windows 7 operating system? The steps will be explained in detail below.

1. Download the PHP installation package

First you need to download the PHP installation package. It can be downloaded from the PHP official website or from a third-party website. It is recommended to download the zip package under Windows, so that you can use the same PHP version on multiple computers.

2. Unzip the PHP installation package

After the download is complete, unzip the compressed package to any folder. Here we extract it to the C:\php\ directory.

3. Configure PHP environment variables

Add the C:\php\ directory to the system environment variables, so that PHP commands can be used in the command line or other programs . The steps are as follows:

• Right-click the "Computer" icon and select "Properties";
• Click "Advanced System Settings" in the left panel;
• Enter In the "System Properties" interface, click the "Environment Variables" button in the "Advanced" tab;
• Find "Path" in "System Variables" and click the "Edit" button;
• In In the pop-up "Edit Environment Variables" window, add the "C:\php\" folder path, and separate multiple paths with semicolons;
• Click "OK" to close all dialog boxes.

4. Configuring the PHP.INI file

The PHP.INI file is the main configuration file of PHP. It includes various configurations required for PHP to run, such as PHP Modules, MySQL, SMTP, etc. We can modify it as needed.

Save the php.ini-development file in the C:\php\ directory as a php.ini file and copy it to the C:\Windows\ directory. In this way, PHP can automatically load the php.ini file in the C:\Windows directory during execution.

5. Test whether PHP is normal

Save the following code as a test.php file and place the file in the C:\inetpub\wwwroot directory:

phpinfo();
?>

Enter http://localhost/test.php in the browser to access it. If the PHP information page appears, PHP has been successfully built normally.

6. Installing MySQL and Apache

During the development process, we usually need to use MySQL as the database and Apache as the web server. Here we recommend using the XAMPP suite, which integrates PHP, MySQL and Apache and is very convenient to install.

Install XAMPP into the C:\xampp\ directory and start the apache and mysql services.

7. Test PHP connection to MySQL

Create a new testmysql.php file in the C:\xampp\htdocs directory and enter the following code:

$host="localhost"; //Database server name
$username="root"; //Connect to mysql username
$password=""; //Connect to mysql password
$ dbname="test"; //The name of the database

//Connect to the database
$conn=mysql_connect($host,$username,$password) or die("Connection failed");

//Select database
mysql_select_db($dbname,$conn);

//Execute SQL statement
$result=mysql_query("select * from test",$conn);

//Output result
while($row = mysql_fetch_array($result)){

echo $row['name'];

}

The database name here is test and the user name is root. Password is empty. Use a browser to open http://localhost/testmysql.php for testing. You can see that all the data in the test table has been output.

So far, the steps to build a PHP development environment locally in Win7 have been explained. In the subsequent development process, PHP, MySQL and Apache can be configured and modified as needed.
