用PHP写的一个冒泡排序法的函数简单实例，php冒泡排序函数
前几天遇到的一道关于算法的考题，要求用PHP语言实现对一个数组进行排序，我写了一个采用冒泡排序法的函数，和大家分享一下。
<?
//冒泡排序法
function bubble_sort($array)
{
$count = count($array);
if($count <= 0)
{
return false;
}
for($i=0; $i<$count; $i++)
{
for($k=$count-1; $k>$i; $k--)
{
if($array[$k] < $array[$k-1])
{
$tmp = $array[$k];
$array[$k] = $array[$k-1];
$array[$k-1] = $tmp;
}
}
}
return $array;
}
$arr = array(3, 5, 1, 4, 2);
$s = bubble_sort($arr);
print_r($s);
?>
以上这篇用PHP写的一个冒泡排序法的函数简单实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持帮客之家。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
