All About Basic

By using func_get_args(), you can capture and handle any number of parameters passed to a function, making your PHP functions more flexible and versatile.

array_walk() and array_map() both are used to work with the individual array element. array_walk() allows for operations to be performed on each element, but it does not return a new array. Instead, it operates directly on the original array and is typically used for side effects like printing, modifying elements in-place, or other operations where the result is not needed in a new array.

On the other hand, array_map() Returns a new array with modified values.

This guide demonstrates how to use braces to properly nest ternary operators in PHP, ensuring correct evaluation and avoiding common errors with practical example.

In Line 7 and 11 you can see how the first braces are used between the ternary operators which makes the output different.

Here I will try to show about how to find different elements between arrays using array_diff and array_diff_assoc functions in PHP. This will help you to understand array differentiation based on values and keys.

Today I will try to explore the PHP functions array_intersect and array_intersect_assoc to find common elements in arrays based on values and keys with example.

Discover how to sort associative arrays by their keys using the ksort() and krsort() functions in PHP. This guide provides practical examples to help you understand how these sorting functions work while preserving the array keys.

Here i am trying to create a custom WordPress plugin that generates a shortcode [post_title_with_pagination] to display post titles with pagination. This step-by-step guide will help you set up the plugin and use it in your WordPress site effectively. Please check Learning Plugins Development: Part 1 to find out the steps.

This PHP script provides an example of how to use rsort() for reverse sorting and arsort() for reverse sorting while preserving the array keys.

<?php
echo "<pre>";
$reverseSort= array("a","d","e","b","c");
echo " <br> Main array <br>";
print_r($reverseSort);
rsort($reverseSort);
echo"<br>After rsort():<br>";
print_r($reverseSort);

$reverseSort1= array("a","d","e","b","c");
echo " <br> Main array <br>";
print_r($reverseSort1);

echo"<br>After rasort() which preserve keys :<br>";
arsort($reverseSort1);
print_r($reverseSort1);

echo "</pre>";
?>

OUTPUT

 Main array 
Array
(
    [0] => a
    [1] => d
    [2] => e
    [3] => b
    [4] => c
)

After rsort():
Array
(
    [0] => e
    [1] => d
    [2] => c
    [3] => b
    [4] => a
)
 
 Main array 
Array
(
    [0] => a
    [1] => d
    [2] => e
    [3] => b
    [4] => c
)

After rasort() which preserve keys :
Array
(
    [2] => e
    [1] => d
    [4] => c
    [3] => b
    [0] => a
)

Discover the various methods for sorting arrays in PHP, including the use of sort() and asort(). This guide provides a detailed explanation on how to sort both indexed and associative arrays while ensuring keys are preserved when necessary.
