復制代碼 代碼如下:

echo urlencode('不要迷戀哥');//輸出:%B2%BB%D2%AA%C3%D4%C1%B5%B8%E7

復制代碼 代碼如下:

$string = "不要迷戀哥";
$length = strlen($string);
echo $string;
$result = array();
//十進制
for($i=0;$i<$length;$i++){
if(ord($string[$i])>127){
$result[] = ord($string[$i]).' '.ord($string[++$i]);
}
}
var_dump($result);
//十六進制
$strings = array();
foreach($result as $v){
$dec = explode(" ",$v);
$strings[] = "%".dechex($dec[0])." "."%".dechex($dec[1]);
}
var_dump($strings);

復制代碼 代碼如下:

$string = '%B2%BB%D2%AA%C3%D4%C1%B5%B8%E7';
$length = strlen($string);
$hexs = array();
for($i=0;$i<$length;$i++){
if($string[$i] == '%'){
$hexs[] = $string[++$i].$string[++$i];
}
}
$num = count($hexs);
for($i=0;$i<$num;$i++){
echo chr(hexdec($hexs[$i])).chr(hexdec($hexs[++$i]));
}
