in same cases you will need to install deprecated PHP version and this is no possible with these commands

brew tap shivammathur/php

brew install shivammathur/php/[email protected]

adding alias to use it

#echo 'alias php7.1="/opt/homebrew/opt/[email protected]/bin/php"' >> ~/.zshrc
#source ~/.zshrc 

to Force the composer to use a specific PHP version you can add this script to the composer.josn

	"config": {
		"optimize-autoloader": true,
		"prepend-autoloader": false,
		"platform": {
			"php": "8.0.13"
		}
	},

or you can use the command line to add it 

cd /path/to/project/dir
ls -l composer.json
composer config platform.php {PHP_VERSION_HERE}
composer config platform.php 8.x.x

the most challenge question in the past was soring a multidimensional arrays in PHP, now lets make it in an easy way

You have your array like this 

$array = [];
$array[] = array('name' => 'name1', 'age' => 85);
$array[] = array('name' => 'name2', 'age' => 15);
$array[] = array('name' => 'name3', 'age' => 10);
$array[] = array('name' => 'name4', 'age' => 59);

the easy way is to use these command 

Clone repository with the same server user

• create new php file with this name it.php

<?php
exec('git clone   https://@github.com/{username}/{repository}.git');

after that  go to the command line and execute this command 

 php it.php
 

the easiest and best way is to use the below code

<?php

$txt1 = file_get_contents('1.txt');
$txt1 .= "\n" . file_get_contents('2.txt');
$txt1 .= "\n" . file_get_contents('3.txt');

$fp = fopen('newText.txt', 'w');
if(!$fp)
    die('Could not create / open text file for writing.');
if(fwrite($fp, $txt1) === false)
    die('Could not write to text file.');

echo 'Text files have been merged.';

?>

usually in PHP we are using cURL to execute GET/ POST/ DELETE/ methods but now I will mention here how to use it in file_get_contents

you need to increase the memory_limit in php.ini

and as a quick solution you can use these commands directly in the command line

php -dmemory_limit=5G bin/magento setup:di:compile

and 

php -dmemory_limit=5G bin/magento setup:static-content:deploy

another code for the composer update

php -dmemory_limit=5G composer.phar update

php -d memory_limit=-1 /usr/local/bin/composer update
 

- Install Homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

- brew install [email protected]

- echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile

- echo 'export PATH="/usr/local/opt/[email protected]/sbin:$PATH"' >> ~/.bash_profile

- source ~/.bash_profile

-open /private/etc/apache2/httpd.conf

- add this line "LoadModule php7_module /usr/local/opt/[email protected]/lib/httpd/modules/libphp7.so"

How to disable auto-save:

• Go to File > Settings (Ctrl+Alt+S).
• Go to Appearance & Behavior > System Settings.
• unchecked: the both fields
  • Save files on frame deactivation
  • Save files automatically if application is idle for x sec.
• Go to Editor > General > Editor Tabs
• Put a checkmark on
  • "Mark modified files with asterisk"

Click Apply > OK.

That's it.

The quickest way to display all php errors and warnings is to add these lines to your PHP code file:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
