PHP 5.3.2

Version of implementation PHP of programming language PHP

PHP 5.3.2 is a maintenance release in the 5.3 series, which includes a large number of bug fixes.

Examples:

Factorial - PHP (56):

This example uses recursive factorial definition.

<?php
function factorial($n)
{
 if ($n == 0) {
 return 1;
 }
 
 return $n * factorial($n - 1);
}
for ($n = 0; $n <= 16; $n++) {
 echo $n . "! = " . factorial($n) . "\n";
}
?>

Hello, World! - PHP (73):

<?php
echo "Hello, World!\n";
?>

Fibonacci numbers - PHP (74):

This example uses recursive definition of Fibonacci numbers.

<?php
function fibonacci($n)
{
 if ($n < 3) {
 return 1; 
 }
 
 return fibonacci($n-1) + fibonacci($n-2); 
}
for ($n = 1; $n <= 16; $n++) {
 echo fibonacci($n) . ", ";
}
echo "...\n";
?>

Quadratic equation - PHP (258):

<?php
echo "A = ";
$A = (float) fgets(STDIN);
if ($A == 0) {
 die("Not a quadratic equation\n");
}
echo "B = ";
$B = (float) fgets(STDIN);
echo "C = ";
$C = (float) fgets(STDIN);
$D = $B * $B - 4 * $A * $C;
if ($D == 0) {
 echo "x = ", -$B / 2.0 / $A, "\n";
 die();
}
if ($D > 0) {
 echo "x1 = ", (-$B + sqrt($D)) / 2.0 / $A, "\n";
 echo "x2 = ", (-$B - sqrt($D)) / 2.0 / $A, "\n";
} else {
 echo "x1 = (", -$B / 2.0 / $A, ", ", sqrt(-$D) / 2.0 / $A, ")\n";
 echo "x2 = (", -$B / 2.0 / $A, ", ", -sqrt(-$D) / 2.0 / $A, ")\n";
}
?>

CamelCase - PHP (307):

This example uses string functions and regular expressions. Function ucwords converts first letter of each word to uppercase.

<?
$text = fgets(STDIN);
$text = str_replace(' ', '', ucwords(preg_replace('/[^a-z]/', ' ', strtolower($text))));
echo $text;
?>
