Many a times it happens that while solving mathematical expressions we require to calculate the square root of a number.

To solve this issue like other programming language PHP provides us with a built-in function sqrt() which can be used to calculate the square root of a number. The sqrt() function in PHP is used to calculate the square root of a number. PHP sqrt function in positive negative decimal number phpmyadmin exploit510

PHP Min() and Max() functions


The PHP min() and max() functions can be used to find lowest or highest value in a list of arguments.


Max(): max() returns the parameter value considered “highest” according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and ‘abc’) the first provided to the function will be returned.

Min(): min() returns the parameter value considered “lowest” according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and ‘abc’) the first provided to the function will be returned. PHP min and max functions



Example 


-200
150


OR


Example 

$array = array(1, 2, 3, 4, 5);
echo(max($array));

echo("\n");          // for breakline

echo(min($array));
