Add ob_start(); function from where you want to put output to a file
Use following function to get output of code execution :
$contents = ob_get_contents();
Put the content to a file:
file_put_contents(<FILE PATH WITH NAME>,$contents);
Clean the output with using ob_end_clean();
Example:
…..
ob_start();
print_r($data);
$contents = ob_get_contents();
file_put_contents(‘var/www/html/dumprequest.txt’,$contents);
ob_end_clean();
Step 1 – Installing Apache
Update the package list for upgrades and new packages:
sudo apt-get update
Now Apache can be installed.
sudo apt-get install apache2
Step 2 – Installing MySql
Install MySql Server
sudo apt-get install mysql-server
After MySql has been installed, you will need to set the root password of the database and secure it using the following command :
sudo mysql_secure_installation
You will be presented a screen where MySQL asks whether you would like to activate the VALIDATE PASSWORD PLUGIN. For now, keeping things simple, type no.
In the next type the root password of your choice. Confirm it again.
In the next screen MySql will ask whether to remove anonymous users. Type yes Disallow root login remotely?
Type No Remove test database and access to it?
Type Yes Reload privilege tables now?
Type Yes
After the password has been set you can check the whether MySQL is working correctly by logging into the database with the command :
sudo mysql -u root -p
Password is the same that was set in the previous step.
Step 3 – Installing PHP with Common Extensions
Now install PHP and commonly used PHP extensions by using the following command :
sudo apt-get install php libapache2-mod-php php-mysql php-curl php-gd php-json php-zip php-mbstring
After PHP has been installed, restart Apache.
sudo service apache2 restart
Update System
sudo apt update && apt upgrade -yInstall PHP 8.2
sudo apt install php8.2 -yIf system doesn’t found this package, then add Ondrej repository :
sudo add-apt-repository ppa:ondrej/phpUpdate system:
sudo apt updateInstall main extensions of PHP 8.2
sudo apt-get install -y php8.2-cli php8.2-common php8.2-fpm php8.2-mysql php8.2-zip php8.2-gd php8.2-mbstring php8.2-curl php8.2-xml php8.2-bcmathCheck PHP installed version:
php --versionCheck installed extensions:
php -m
or
php8.2 -m (If you are using multiple versions of PHP)For PHP 7.x
sudo service php7.x-fpm startReload configuration without start
sudo service php7.x-fpm stop
sudo service php7.x-fpm restart <- restart it
sudo service php7.x-fpm reload <-
For PHP 8.x
sudo service php8.x-fpm startReload configuration without start
sudo service php8.x-fpm stop
sudo service php8.x-fpm restart <- restart it
sudo service php8.x-fpm reload <-
Update the cache using:
sudo apt-get updateInstall the package using:
sudo apt-get install sqlitebrowserAdd UITextField in your controller or view
class UITextViewController: UIViewController{
@IBOutlet weak var mtnGSMtxt: UITextField!
override func viewDidLoad() {
mtnGSMtxt.delegate = self
super.viewDidLoad()
}
}
Now extend defined class with UITextFieldDelegate:
extension UITextViewController : UITextFieldDelegate{
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
//For GSM numer validation
let maxLength = 12
if textField == mtnGSMtxt {
let gsmLength = Int(mtnGSMtxt.text?.count ?? 0)
if gsmLength >= 0 && gsmLength < maxLength{
let allowedCharacters = CharacterSet(charactersIn:"0123456789 ")//Here change this characters based on your requirement
let characterSet = CharacterSet(charactersIn: string)
return allowedCharacters.isSuperset(of: characterSet)
}else{
return false
}
}
return true
}
}Exporting from MySQL :
mysqldump -u mysql_username -p database_name > output_file.sql
You can put absolute or relative path of output_file.sql
Enter the database password.Eg. : mysqldump -u root -p blueheri > blueheri.sql
Importing to MySQL :
mysql -u username -p database_name < input_file.sql
You can put absolute or relative path of input_file.sql
Enter the database password.Eg. mysql -u root -p blueheri < blueheri.sql
Add following lines in PHP file:
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
A. ) Temporary Solution
If you installed new version of ruby, but ruby -v still showing old version.
$ brew install rbenv
$ export PATH=”$HOME/.rbenv/bin:$PATH”
$ eval “$(rbenv init -)”
Check ruby version by ruby -v command
B. ) Permanent Solution
sudo nano /etc/paths
Certificate received from server is NOT trusted by this system, an exception has been added by the user to trust this specific certificate.
Failed to initialize NLA, do you have correct Kerberos TGT initialized ?
Failed to connect, CredSSP required by server (check if server has disabled old TLS versions, if yes use -V option)
Solution: Connect system with other computer, which have new versions of TLS. Follow the following steps after connect to windows server.
