PHP provides several built-in math functions, which are used to perform mathematical tasks in the PHP program. These functions make it easier to perform mathematical operations.
There are some important math functions following
The PHP max() function is used to get the highest value from the values used in an array.
Syntax:
max( $array );
OR
max( value1, value2, value3 );
Let's create a program to get the highest value with the PHP max() function.
<!DOCTYPE html>
<html>
<body>
<?php
$array1 = array( 5, 10, 15, 20 );
$array2 = array( 10, 20, 30, 40 );
echo max( $array1 ) ."<br>"; // get highest value from array
echo max( $array2 ) ."<br>";
echo max( 20,35,40,55 ) ."<br>"; // get directly highest value from array values
?>
</body>
</html>
The PHP Max () function is used to get the lowest/minimum value from the array. And you can also pass direct values or array in PHP min() function.
Syntax:
min( $array );
OR
min( value1, value2, value3 );
Let's create a program to get the lowest value with the PHP max() function.
<!DOCTYPE html>
<html>
<body>
<?php
$array1 = array( 20, 40, 60, 80 );
$array2 = array( 7, 14, 21, 28 );
echo min( $array1 ) ."<br>"; // get lowest value from array
echo min( $array2 ) ."<br>";
echo min( 15,30,45,60 ) ."<br>"; // get directly lowest value from array values
?>
</body>
</html>
With the PHP abs () function, we can get the absolute value of a value/number. The positive form of a number is obtained by this function.
Syntax:
abs( $number );
Let's create a program to get absolute value with PHP abs() function.
<!DOCTYPE html>
<html>
<body>
<?php
$number1 = 9 ; // Positive Integer value.
$number2 = -9 ; // Negative Integer value.
$number3 = 2.5 ; // Positive Float value.
$number4 = -3.7; // Negative Float value.
# Print all absolute numbers
echo abs( $number1 ) ."<br>";
echo abs( $number2 ) ."<br>" ;
echo abs( $number3 ) ."<br>";
echo abs( $number4 ) ."<br>";
?>
</body>
</html>

// Print round values
echo round( $number1 ) . "<br>" ;
echo round( $number2 ) . "<br>" ;
echo round( $number3 ) . "<br>" ;
echo round( $number4 ) . "<br>" ;
?>
</body>
</html>

Syntax:
ceil( $number ) ;

// Print round values
echo ceil( $number1 ) . "<br>" ;
echo ceil( $number2 ) . "<br>" ;
echo ceil( $number3 ) . "<br>" ;
?>
</body>
</html>
The PHP floor () function is used to round values to the lowest integer value.
Syntax:
floor( $number ) ;

echo floor( $number2 ) . "<br>";
echo floor( $number3 ) . "<br>";
?>
</body>
</html>
The PHP rand () function is used to generate a random integer number by a given range. If you do not pass a value in this function it automatically generates a random number between 8 and 10 digits.
Syntax:
rand( );
OR
rand ( min_value , max_value );
Let's create a program to generate random numbers with PHP rand() function.
<!DOCTYPE html>
<html>
<body>
<?php
# Assigned two varriable for Minimum and Maximum values
$min_value = 5;
$max_value = 20;
# Print generated random integers
echo rand() ."<br>"; // Automatically generate random integer values
echo rand( $min_value,$max_value ) ."<br>"; // Generate integer values by a given range
?>
</body>
</html>
The PHP mt_rand () function acts like the rand () function. But the mt_rand function used the Mersenne Twister algorithm to generate random integer values / numbers. that function is faster than rand() function.
Syntax:
mt_rand( );
OR
mt_rand ( min_value , max_value );
Let's create a program to generate random integers with PHP mt_rand() function.
<!DOCTYPE html>
<html>
<body>
<?php
# Assigned two varriable for Minimum and Maximum values
$min_value = 5;
$max_value = 10;
# Print generated random integers
echo mt_rand() ."<br>"; // Automatically generate random integer values
echo mt_rand( $min_value,$max_value ) ."<br>"; // Generate integer values by a given range
?>
</body>
</html>
