First we have to open AppServiceProvider.php in app/Providers.

Add View facade to the service provider

use Illuminate\Support\Facades\View;

After adding View Facade add composer code to boot function

function boot()
{
       View::composer('page.index', function($view){
            $view->with('data', 'Value This could output of eloquent too')
        });
}

NOTE:

• page.index is the location of targeted blade file in view folder
• You can also use wildcard to target all blade file in a directory (page.*)
• To target more than one file you can pass array instead of string.

fopen ("php://stdin","r") // open a read stream

So to get a input from user in cli.

echo "Type Something: "
$r_stream = fopen ("php://stdin","r");
$input = trim(fgets($r_stream));
echo = "\n";
echo "You Entered ".$input;

You can run the php file by opening your CMD in a Windows machine or Terminal in Linux based machine

And Getting to the directory in which file is stored and typing the command below.

php file_name.php

In autoload object add the following file array:-

"autoload": {
    "files": [
        "app/helpers.php"
    ]
},

After adding this we need to run the following command Make sure composer is installed.

composer dump-autoload

This will create a helpers.php file in your app folder. Which will be accessed by all controllers and view files.

Best way to add a function in your Helper file is to check if it already exist or not

<?php
if (! function_exists('your_custom_helper')) {
function your_custom_helper($string) {
   // your code
}
}

• Pass all the Argument in the form of an array

function sum(array $args){
    $sum = 0;
    
    if( is_numeric( implode("", $args) ) ) 
        {
            foreach($args as $arg){
                $sum += $arg;
                }
            return $sum;
        }
  return "Only array with numeric value accepted";
    
}

// if input is an array with values 1, 2, 3, 5
print_r ( sum([1, 2, 3, 5]) );

//output is 11

• Use func_get_args () to get all the passed argument

function makeUrl() {
$args = func_get_args();
  $url = 'https://www.maxester.com/blog/';
  $imp = implode('-', array_filter($args) );
  return $url.lcreplace( $imp ) ;
}

function lcreplace($url) {
return str_replace( "--", "-", preg_replace('/[^A-Za-z0-9-]/', "-", strtolower($url) ) );
}

// input
print_r( makeUrl( "How", "To", "pass", "infinite", "argument", "in", "PHP" ) );
  
//output

• Use PHP Spread Operator( […$array] )

function makeUrl(...$args) {

  $url = 'https://www.maxester.com/blog/';
  $imp = implode('-', array_filter($args) );
  return $url.lcreplace( $imp ) ;
}

function lcreplace($url) {
return str_replace( "--", "-", preg_replace('/[^A-Za-z0-9-]/', "-", strtolower($url) ) );
}


// input
print_r( makeUrl( "How", "To", "pass", "infinite", "argument", "in", "PHP" ) );
  
//output

Each method mentioned above has its own advantages.

These are accessed by the variables on which they are defined or invoked dynamically.

$yourVariable = function(){return 1+1};
//now the variable has 2 as value

$areaOfCircle = function($a){ return 3.14*$a*$a;};
$yourOtherVariable = $areaOfCircle(7);
//now the variable has 153.86 as value

User::where('status' ,'=' ,1)->where('payment', '=' ,1)->get();

Sometimes We need to add orWhere condition to our queries, between two cases. This might interfere with other conditions so we need to pass them in a function.

->where( function($query) {
	$query->where('parent_id', '=', 1)
              ->orWhere('parent_id','=' ,2);
} )

To get external variables pass them with use

->where( function($query) use ($case1, $case2) {
	$query->where('parent_id', '=', $case1)
              ->orWhere('parent_id', '=' ,case2);
} )
