简单粗爆的方式：
这个是从github中的Stichoza\GoogleTranslate中抠出来的，
项目地址：https://github.com/Stichoza/google-translate-php
用composer安装：
composer require stichoza/google-translate-php
将vendor\stichoza\google-translate-php\src\GoogleTranslate.php中的
https://translate.google.com/translate_a/single
改为
https://translate.google.cn/translate_a/single
国为有墙
错误解决方法：cURL error 60: SSL certificate problem: unable to get local issuer certifica
下载cacert.pem(https://curl.haxx.se/ca/cacert.pem);
打开php.ini 搜索curl.cainfo 与 openssl.cafile,将其配置成你自己cacert.pem文件的路径
curl.cainfo=" 路径 "
openssl.cafile="路径"
其实很多参数不一定要，下面是个人整理的必须的参数
google检测语言接口：
https://translate.google.cn/translate_a/single?client=webapp&sl=auto&q=china&tk=126587.515333
q为检测的文字，tk用下写的算法加密生成，其它保持默认
google翻译接口：
其中sl为源语言，tl为目标语言，tk参数是由以下方法生成的：$a为要翻译的文字（中国人），其它参数保持默认即可
private function TL($a)
{
$tkk = $this->TKK();
$b = $tkk[0];
for ($d = [], $e = 0, $f = 0; $f < $this->JS_length($a); $f++) {
$g = $this->JS_charCodeAt($a, $f);
if (128 > $g) {
$d[$e++] = $g;
} else {
if (2048 > $g) {
$d[$e++] = $g >> 6 | 192;
} else {
if (55296 == ($g & 64512) && $f + 1 < $this->JS_length($a) && 56320 == ($this->JS_charCodeAt($a, $f + 1) & 64512)) {
$g = 65536 + (($g & 1023) << 10) + ($this->JS_charCodeAt($a, ++$f) & 1023);
$d[$e++] = $g >> 18 | 240;
$d[$e++] = $g >> 12 & 63 | 128;
} else {
$d[$e++] = $g >> 12 | 224;
}
$d[$e++] = $g >> 6 & 63 | 128;
}
$d[$e++] = $g & 63 | 128;
}
}
$a = $b;
for ($e = 0; $e < count($d); $e++) {
$a += $d[$e];
$a = $this->RL($a, '+-a^+6');
}
$a = $this->RL($a, '+-3^+b+-f');
$a ^= $tkk[1] ? $tkk[1] + 0 : 0;
if (0 > $a) {
$a = ($a & 2147483647) + 2147483648;
}
$a = fmod($a, pow(10, 6));
return $a.'.'.($a ^ $b);
}
其它与上述算法相关的代码
