PHP max() Function Last Updated : 10 Sep, 2024 Comments Improve Suggest changes Like Article Like Report The max() function is an inbuilt function in PHP, used to find the numerically maximum value in an array or the numerically maximum value of several specified values. Syntaxmax(array_values) or max(value1, value2, ...)ParametersThis function accepts two different types of arguments which are explained below:array: You can pass a single array to the max() function to find the maximum value within the array.value1, value2, value3, ...: A comma-separated list of values or variables that you want to compare. These values can be of different types (integers, floats, strings, etc.).Return ValueThe max() function returns the numerically maximum value from the given values or from the array.Find Maximum Value using max() Function with Multiple ValuesThe max() function can be used with multiple values (or variables) to find the largest one. PHP compares these values and returns the highest value.Example 1: Comparing Integers PHP <?php echo (max(12, 4, 62, 97, 26)); ?> Output97Example 2: Comparing Floats PHP <?php // Comparing Float Values echo max(3.5, 7.2, 6.8); ?> Output7.2Example 3: Comparing StringsWhen comparing strings, PHP uses the ASCII values of the characters to determine the "largest" string. PHP <?php // Comparing Strings echo max("Apple", "Banana", "Cherry"); ?> OutputCherryUsing the max() Function with an ArrayThe max() function can also be used to find the maximum value in an array. If the array contains mixed data types (e.g., numbers and strings), PHP will compare the values based on their types and return the largest value.Example 1: Finding the Maximum Value in a Numeric Array PHP <?php // Integer Array $numbers = [10, 50, 30, 70, 20]; // Find the Largest Value echo max($numbers); ?> Output70Example 2: Finding the Maximum Value in an Array with Mixed Types PHP <?php // Array with Mixed Data Types $values = [3, "20", 5.5, "Apple", 15]; // Find the Maximum Value echo max($values); ?> Output15 Comment More infoAdvertise with us Next Article PHP Syntax S Shubrodeep Banerjee Follow Improve Article Tags : Misc Web Technologies PHP PHP-function Practice Tags : Misc Similar Reads PHP Tutorial PHP is a popular, open-source scripting language mainly used in web development.
