PHP生成短网址的3种方法代码实例,php生成3种实例
短网址服务,可能很多朋友都已经不再陌生,现在大部分微博、手机邮件提醒等地方已经有很多应用模式了,并占据了一定的市场。估计很多朋友现在也正在使用。 看过新浪的短连接服务,发现后面主要有6个字符串组成。
太多算法的东西,也没必要去探讨太多,最主要的还是实现,下面是三种方法的代码:
<?php //纯随机生成方法 function random($length, $pool = '') { $random = ''; if (empty($pool)) { $pool = 'abcdefghkmnpqrstuvwxyz'; $pool .= '23456789'; } srand ((double)microtime()*1000000); for($i = 0; $i < $length; $i++) { $random .= substr($pool,(rand()%(strlen ($pool))), 1); } return $random; } $a=random(6); print_r($a); // 枚举生成方法 function shorturl($input) { $base32 = array ( "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" ); $hex = md5($input); $hexLen = strlen($hex); $subHexLen = $hexLen / 8; $output = array(); for ($i = 0; $i < $subHexLen; $i++) { $subHex = substr ($hex, $i * 8, 8); $int = 0x3FFFFFFF & (1 * ('0x'.$subHex)); $out = ''; for ($j = 0; $j < 6; $j++) { $val = 0x0000001F & $int; $out .= $base32[$val]; $int = $int >> 5; } $output[] = $out; } return $output; } $a=shorturl("http://www.bkjia.com"); print_r($a); //62 位生成方法 function base62($x) { $show= ''; while($x> 0) { $s= $x% 62; if($s> 35) { $s= chr($s+61); } elseif($s> 9 && $s<=35) { $s= chr($s+ 55); } $show.= $s; $x= floor($x/62); } return $show; } function urlShort($url) { $url= crc32($url); $result= sprintf("%u", $url); return base62($result); } echo urlShort("http://www.bkjia.com/"); ?>

你foreach后的{}应该把后面的内容都括进来
正确的是
$con=array(array('新闻标题','新闻内容'),array('新闻标题2','新闻内容2'));
foreach($con as $id=>$val){
$title=$val[0];
$content=$val[1];
$path=$id.'.htm';
$fp=fopen("tmp.htm","r"); //只读打开模板
$str=fread($fp,filesize("tmp.htm"));//读取模板中内容
$str=str_replace("{title}",$title,$str);
$str=str_replace("{content}",$content,$str);//替换内容
fclose($fp);
$handle=fopen($path,"w"); //写入方式打开新闻路径
fwrite($handle,$str); //把刚才替换的内容写进生成的HTML文件
fclose($handle);
echo "生成成功";
}
