python改写成php,将Python代码转换为PHP
python改写成php,将Python代码转换为PHP
我创建了一个名为py2php的python-to-php转换器。它可以自动翻译基本逻辑，然后你将需要调整图书馆调用等仍然是实验性的。
下面是从OP提供的python中自动生成的PHP<?php
require_once(‘py2phplib.php’);
require_once( ‘math.php’);
function calcNumEntropyBits($s) {
if ((count($s) <= 0)) {
return 0.0;
}
$symCount = array();
foreach( $s as $c ) {
if (!$symCount.contains($c)) {
$symCount[$c] = 1;
}
else {
$symCount[$c] += 1;
}
}
$entropy = 0.0;
foreach( $symCount->iteritems() as $temp_c ) {
$prob = ($n / float(count($s)));
$entropy += ($prob * (math::log($prob) / math::log(2)));
}
if (($entropy >= 0.0)) {
return 0.0;
}
else {
return -($entropy * count($s));
}
}
function testEntropy($s) {
pyjslib_printFunc(sprintf(‘Bits of entropy in '%s' is %.2f’, new pyjslib_Tuple([$s, calcNumEntropyBits($s)])));
}
testEntropy(‘hello world’);
testEntropy(‘bubba dubba’);
testEntropy(‘aaaaaaaaaaa’);
testEntropy(‘aaaaabaaaaa’);
testEntropy(‘abcdefghijk’);
由于数学导入和包含，它将无法正确运行，但这些将很容易手工修复。
