PHP get the max/maximum/largest value in array. This tutorial has the purpose to explain to you several easy ways to find or get the maximum or largest value from an array in PHP.

Here, we will take e.g. PHP gets the maximum value in an array, get the largest number in the array PHP without a function or get the max value from an array in PHP using for loop

PHP find the highest value in an array

You can use the PHP max() function, which is used to find the largest number from an array in PHP.

Before we use the take examples, you must know about the PHP max() function.

PHP max() function

The max() function is inbuilt PHP function, which is used to find the numerically maximum or highest value in an array or find maximum or highest value of given specified values.

Syntax

 max(array)  
 or
 max(value1, value2, value3 … valueN)

Example – 1 Get max value in array PHP using max() function

Let’s take the first example, we will use the PHP max() function to find the maximum value in the array. Let’s see the example below:

<?php
 
$array = [1, 10, 50, 40, 2, 15, 100];
 
$res = max($array);
 
print_r($res);
 
?> 

The output of the above program is: 100

Example – Find largest number in array php without function

Let’s take the second example, in this example, we will find or get the largest or maximum number in array PHP without function. Let’s see the example below:

<?php
 
$array = array(1000,400,10,50,170,500,45);
 
$max = $array[0];
 
foreach($array as $key => $val){
 
    if($max < $val){
 
        $max = $val;
         
    }
}   
 
print $max;
 
?> 

The output of the above program is: 1000

Example – 3 PHP get max or highest value in array using for loop

Let’s take the third example, to find the maximum or largest or highest value in array PHP without using any function. Let’s look at the examples below:

<?php 
 
$array = array(500, 20, 55 ,165, 456, 78, 75);
 
$max = 0;
 
for($i=0;$i<count($arr);$i++)
 {
    if ($arr[$i] > $max)
    {
        $max = $arr[$i];
    }
}
 
print $max;
 
?>
