In PHP, you can utilize the following code to generate random strings:

function generateRandomString($length = 10) {
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $randomString = '';
    
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, strlen($characters) - 1)];
    }
    
    return $randomString;
}

// 生成一个长度为10的随机字符串
$randomString = generateRandomString();
echo $randomString;

This code defines a function called generateRandomString, which takes a parameter $length to specify the length of the generated random string, defaulting to 10. Inside the function, a character set $characters containing numbers, lowercase letters, and uppercase letters is defined. Then, by looping through and randomly selecting characters, they are concatenated to create the final random string.

You can use the generateRandomString function to generate random strings of varying lengths as needed.
