PHP max() function
The PHP math max function is used to return the highest value from a set of expressions.
Syntax
max( array) OR max(number1, number2....) |
Parameters in
max function
The parameters of the max function are:
Parameter |
Description |
array |
It specifies a array. |
OR number1, number2 |
It specifies numbers( at least two number is required). |
Example of max function
The following sample of the max function obtains the highest number of two or more numbers. The highest number specified in each function is returned.
<?php
$val1=max(34,4,90,6,78);
$val2=max(1,2);
$val3=max('abcd','dsef','fgre');
$val4=max(array(1,-2,5,8));
echo "max value of <b>max(34,4,32,6,78)</b> is <b>$val1</b> <br />";
echo "max value of <b>max(1,2)</b> is <b>$val2</b> <br />";
echo "max value of <b>max('abcd','dsef','fgre')</b> is <b>$val3</b> <br />";
echo "max value of <b>max(array(1,-2,5,8))</b> is <b>$val4</b> <br />";
?>
Output
PHP min() function
The PHP math min function is used to return the minimum value from a set of expressions.
Syntax
min( array) OR min(number1, number2....) |
Parameters in
min function
The parameters of the "min" function are:
Parameter |
Description |
array |
It specifies a array. |
OR number1, number2 |
It specifies numbers( at least two number is required). |
Example of min function
The following sample of the min function obtains the lowest number of two or more numbers. The lowest number specified in each function is returned.
<?php
$val1=min(34,4,90,6,78);
$val2=min(1,2);
$val3=min('abcd','dsef','fgre');
$val4=min(array(1,-2,5,8));
echo "min value of <b>min(34,4,32,6,78)</b> is <b>$val1</b> <br />";
echo "min value of <b>min(1,2)</b> is <b>$val2</b> <br />";
echo "min value of <b>min('abcd','dsef','fgre')</b> is <b>$val3</b> <br />";
echo "min value of <b>min(array(1,-2,5,8))</b> is <b>$val4</b> <br />";
?>
Output
PHP mt_getranmax function
The PHP math mt_getranmax function is used to return the maximum value that can be returned by the mt_rand() function.
Syntax
Example of mt_getranmax function
The following is an example of the mt_getranmax function:
<?php
$val=mt_getrandmax();
echo "Maximum value of mt_getrandmax() function is <b> $val</b>";
?>
