PHP access global variable in function

Today, We want to share with you PHP access global variable in function.In this post we will show you PHP $GLOBALS (super global) variable, hear for Accessing a Global Variable Inside a Function we will give you demo and example for implement.In this post, we will learn about How to assign global variable value in a function in php? with an example.

PHP access global variable in function

There are the Following The simple About PHP access global variable in function Full Information With Example and source code.

As I will cover this Post with live Working example to develop how to use global variable inside function in php, so the php global variable in function for this example is following below.

Way : 1 php access variable outside function

// global scope
$product_data = "Old Product Data Value";

function product_function($data) {
   global $product_data;
   $product_data = "New Data value";
}

function category_function(){
    global $product_data;
    product_function("test test test");
}

Way : 2 php set global variable in function

function foo(){
  $GLOBALS['product_id'] = 'product_id';
}
function bar(){
  echo $GLOBALS['product_id'];
}
foo();
bar();

Way : 3 php global variable across files

<?php

//this is old value
$product_data = "Old Product Data Value";

//need to change the value of global variable
product_function($product_data);
echo $product_data;

function product_function(&$data) {
    $data = "New value";
}
?>

Way : 4 Declaring a global variable inside a function

// global scope
$product_id = 1;

product_function($rid){
   global $product_id;
   $product_id = $rid;
}

category_function(){
    global $product_id;
    sendValue($product_id);
}

Way : 5 PHP Global Variable Example: Playing with Scope in PHP

$global = "I am a global variable because I wasn't defined inside a function.";

product_function();
category_function($global);
function product_function() { 
     global $global; 
     echo $global;
}

function category_function($global) {
     echo $global;
}

function category_else_global() {
    global $category_global;
    $category_global = "I'm global becuase the word global was used inside a function.";
}
category_else_global();
echo $category_global;

PHP Array Tutorial With Examples

Today, We want to share with you PHP Array Tutorial With Examples.In this post we will show you PHP Arrays Cheatsheet – everything you need to know, hear for Top Most Frequently Used And Useful PHP Array Operations we will give you demo and example for implement.In this post, we will learn about PHP Indexed, Associative, and Multidimensional Arrays with an example.

PHP Array Tutorial With Examples – filter array

There are the Following The simple About PHP Array Tutorial With Examples Full Information With Example and source code.

As I will cover this Post with live Working example to develop php filter multidimensional array by value, so the some remove blank value from array php for this example is following below.

How to Filter Array by Value in PHP

Simple PHP array_filter() methods filters all the data elements of an array using a simple userdefine callback function as well as returns the filtered data array. Here I shall provide a short scripts to filter data elements of an array that all the contain a specific data value. It will help you to filter an array based on specific if else or any condition with PHP Array Tutorial With Examples.

$players = array(
    'first' => 'Ajay',
    'second' => 'Rahul',
    'third' => 'Virat'
);

$filter_product_array = array_filter($players, function ($param) {
    return (strpos($param, 'Aja') === false);
});

// Output the filtered array
print_r($filter_product_array);

php filter multidimensional array by value

This Example show to you Filtering Multi-Dimensional Arrays in PHP

Input Array

Array
(
    [0] => Array
        (
            [name] => Jasurya
            [email] => [email protected]
            [dept] => Manager
        )

    [1] => Array
        (
            [name] => Binny
            [email] => [email protected]
            [dept] => ERP
        )

    [2] => Array
        (
            [name] => Austin
            [email] => [email protected]
            [dept] => HR
        )

    [3] => Array
        (
            [name] => Vishal
            [email] => [email protected]
            [dept] => Manager
        )

    [4] => Array
        (
            [name] => Mayur
            [email] => [email protected]
            [dept] => ERP
        )

)

Example 2

<?php
$students = array(
    array("name"=>"Jasurya", "email"=>"[email protected]", "dept"=>"Manager"),
    array("name"=>"Binny", "email"=>"[email protected]", "dept"=>"ERP"),
    array("name"=>"Austin", "email"=>"[email protected]", "dept"=>"HR"),
    array("name"=>"Vishal", "email"=>"[email protected]", "dept"=>"Manager"),
    array("name"=>"Mayur", "email"=>"[email protected]", "dept"=>"ERP")
);

$filter = "ERP";

$new_array = array_filter($students, function($var) use ($filter){
    return ($var['dept'] == $filter);
});

echo "<pre>";
print_r($new_array);
?>

Output:

Array
(
    [1] => Array
        (
            [name] => Binny
            [email] => [email protected]
            [dept] => ERP
        )

    [4] => Array
        (
            [name] => Mayur
            [email] => [email protected]
            [dept] => ERP
        )

)

PHP array_merge Function

<?php
$product_color=array(3=>"red",4=>"green");
print_r(array_merge($product_color));
echo "<br/>";

$product_color1=array("a"=>"red","b"=>"green");
$product_color2=array("c"=>"blue","b"=>"yellow");
print_r(array_merge($product_color1,$product_color2));
echo "<br/>";

$product_color1=array("red","green");
$product_color2=array("blue","yellow");
print_r(array_merge($product_color1,$product_color2));
?>

Filtering Array by Mutiple Key Values:

Consider the following example

<?php
$students = array(
    array("name"=>"Jasurya", "email"=>"[email protected]", "dept"=>"Manager"),
    array("name"=>"Binny", "email"=>"[email protected]", "dept"=>"ERP"),
    array("name"=>"Austin", "email"=>"[email protected]", "dept"=>"HR"),
    array("name"=>"Vishal", "email"=>"[email protected]", "dept"=>"Manager"),
    array("name"=>"Mayur", "email"=>"[email protected]", "dept"=>"ERP")
);

$filter = array("Binny", "Vishal");

$new_array = array_filter($students, function($var) use ($filter){
    return in_array($var['name'], $filter);
});
echo "<pre>";
print_r($new_array);
?>

Output:

Array
(
    [1] => Array
        (
            [name] => Binny
            [email] => [email protected]
            [dept] => ERP
        )

    [3] => Array
        (
            [name] => Vishal
            [email] => [email protected]
            [dept] => Manager
        )

)

php filter array of objects

$new_array = array_filter($array, function($obj){
    if (isset($obj->products)) {
        foreach ($obj->products as $product) {
            if ($product->id == 11) return false;
        }
    }
    return true;
});

array filter php

<?php
function even($value)
{
  return $value % 2 == 0;
}

$pids = [1, 2, 3, 4, 5];
print_r(array_filter($pids,"even"));

PHP ARRAY_FILTER_USE_KEY

<?php
$pids = ['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4];
$data = array_filter($pids, function($k) {
  return $k == 'b';
}, ARRAY_FILTER_USE_KEY);
print_r($data);

php array map

<?php
function playerFilter($v)
{
if ($v==="Virat")
  {
  	return "Anushnka";
  }
return $v;
}

$players=array("Yuvraj","Virat","Pant");
print_r(array_map("playerFilter",$players));
?>

php array filter by list of keys

array_filter_key.php

function array_filter_key(array $array, $callback)
{
	$same_keys = array_filter(array_keys($array), $callback);
	return array_intersect_key($array, array_flip($same_keys));
