In this article we will show you the solution of PHP get first element of array, an array is a homogenous collection of elements. We can get the first element of an array by using different methods using php.

In this tutorial, we are going to use two different methods :-

Reset() : this function in php is used to move the pointer to the first element
Array_key_first() : this function is used to get the key of the first element of the array

Step By Step Guide On PHP Get First Element Of Array :-

Let us see examples of two different methods to get the first element of the array

Method 1

In the example below, we are going to use reset() function.

<!DOCTYPE html&g;
<html lang = " en " &g;
<head&g;
    <meta charset = " UTF - 8" &g;
    <meta http-equiv = " X-UA-Compatible " content = " IE=edge " &g;
    <meta name = " viewport " content = " width = device-width , initial-scale = 1.0 " &g;
    <title&g; php get first element of array </title&g;
</head&g;
<body&g;
    <h1 style=" color : rgb(113, 221, 113) ;"&g; TALKERSCODE </h1&g;
    <h2&g; php get first element of array </h2&g;
    <?php
    $color = array('red', 'black', 'white', 'green', 'blue', 'pink') ;
    echo reset($color) ;
    ?&g;
</body&g;
</html&g;

First, we write <! DOCTYPE html&g; which we used as the instruction to the web browser about what version of HTML file is written in.
Secondly, the <html&g; tag is used to indicate the beginning of an HTML document.
As above now the <head&g; tag is used to contain information about the web page. In this tag, a <title&g; tag is used which helps us to specify a webpage title.
Both <head&g; and <title&g; tags are Paired tags. So, both have </head&g; and </title&g; ending tags respectively.
Thirdly, the <body&g; tag is used to define the webpage body. All the contents to show on the website are written here.
<h1&g; tag used to add heading here.
Now we close the HTML file with </html&g; tag
we write <?php tag to write PHP within it.
First create an array with some values.
Using echo reset() to get the first element.
?&g; to close the php code.

Method 2

In this method, we are going to use array_key_first() function.

<!DOCTYPE html&g;
<html lang = " en " &g;
<head&g;
    <meta charset = " UTF - 8" &g;
    <meta http-equiv = " X-UA-Compatible " content = " IE=edge " &g;
    <meta name = " viewport " content = " width = device-width , initial-scale = 1.0 " &g;
    <title&g; php get first element of array </title&g;
</head&g;
<body&g;
    <h1 style=" color : rgb(113, 221, 113) ;"&g; TALKERSCODE </h1&g;
    <h2&g; php get first element of array </h2&g;
    <?php
$flowers = array('rose', 'tulip', 'peony', 'jasmine', 'lavender', 'lavender', 'lotus', 'daisy');
foreach ($flowers as $index =&g; $array) {
    if($index === array_key_first($flowers)) {
        echo $array ;
    }
}
?&g;
</body&g;
</html&g;

First, we write <! DOCTYPE html&g; which we used as an instruction to the web browser about what version of HTML file is written in.
Secondly, the <html&g; tag is used to indicate the beginning of an HTML document.
As above now the <head&g; tag is used to contain information about the web page. In this tag, a <title&g; tag is used which helps us to specify a webpage title.
Both <head&g; and <title&g; tags are Paired tags. So, both have </head&g; and </title&g; ending tags respectively.
Thirdly, the <body&g; tag is used to define the webpage body. All the contents to show on the website are written here.
<h1&g; tag used to add heading here.
Now we close the HTML file with </html&g; tag
we write <?php tag to write PHP within it.
First create an array with some values.
Create the foreach loop then create an if condition within it. Using the array_key_first() method to get the value of the first key to an array then use echo to print the value of the first element.
Close the php code with ?&g; tag.
