How to get the path of the PHP BIN from PHP?

You can use:
您可以使用：
$_SERVER['_']
Also, the predefined constant PHP_BINDIRgives the directory where the php executable is found.
此外，预定义的常量PHP_BINDIR给出了 php 可执行文件所在的目录。
Looks like, for security reasons, $_SERVERvalues are not exposed. (I guess. Please correct me if I'm wrong).
看起来，出于安全原因，$_SERVER值没有公开。（我猜。如果我错了，请纠正我）。

Linux OnlyUse the "which" command to find php.
Linux Only使用“which”命令来查找php。
$phpPath = exec("which php");
Note this does not guarantee the same php executable that your web server may be using, but rather the first instance that was found while looking through the paths.
请注意，这并不能保证您的 Web 服务器可能正在使用相同的 php 可执行文件，而是保证在查看路径时找到的第一个实例。

A method using environment variables, assuming the php executable is in the system path.
一种使用环境变量的方法，假设 php 可执行文件在系统路径中。
function getPHPExecutableFromPath() {
$paths = explode(PATH_SEPARATOR, getenv('PATH'));
foreach ($paths as $path) {
// we need this for XAMPP (Windows)
if (strstr($path, 'php.exe') && isset($_SERVER["WINDIR"]) && file_exists($path) && is_file($path)) {
return $path;
}
else {
$php_executable = $path . DIRECTORY_SEPARATOR . "php" . (isset($_SERVER["WINDIR"]) ? ".exe" : "");
if (file_exists($php_executable) && is_file($php_executable)) {
return $php_executable;
}
}
}
return FALSE; // not found
}

Maybe the best solution is in the Symfony process component: https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Process/PhpExecutableFinder.phpand https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Process/ExecutableFinder.php. In use:
也许最好的解决方案是在 Symfony 进程组件中：https: //github.com/symfony/symfony/blob/master/src/Symfony/Component/Process/PhpExecutableFinder.php和https://github.com/symfony/symfony /blob/master/src/Symfony/Component/Process/ExecutableFinder.php。正在使用：
<?php
use Symfony\Component\Process\PhpExecutableFinder;
$phpFinder = new PhpExecutableFinder;
if (!$phpPath = $phpFinder->find()) {
throw new \Exception('The php executable could not be found, add it to your PATH environment variable and try again');
}
return $phpPath;

In windows, using wamp, you can use the ini variable - extension_dir - as it is placed in the php folder.
在 Windows 中，使用 wamp，您可以使用 ini 变量 - extension_dir - 因为它位于 php 文件夹中。
like this:
像这样：
echo str_replace('ext/', 'php.exe', ini_get('extension_dir'));

Normally, in a simple default PHP installation under Windows, the php.ini file is located and loaded from same directory of PHP binary.
通常，在 Windows 下的简单默认 PHP 安装中，php.ini 文件位于并从 PHP 二进制文件的同一目录加载。
To simplify, Windows users:
为简化起见，Windows 用户：
echo dirname(php_ini_loaded_file()).DIRECTORY_SEPARATOR.'php.exe';
voilà!
瞧！
Of course, if you are using multiple ini files, may not work if the files are not into the same PHP binary directory. BTW, this may solve to most of cases. Windows developers running PHP from local development environment.
当然，如果您使用多个 ini 文件，如果这些文件不在同一个 PHP 二进制目录中，则可能不起作用。顺便说一句，这可能会解决大多数情况。Windows 开发人员从本地开发环境运行 PHP。

It's very easy!
这很容易！
var_dump(getenv('PHPBIN'));
But it works only in windows, so we should use this ansver - https://stackoverflow.com/a/3889630/2574125
但它只适用于 Windows，所以我们应该使用这个 ansver - https://stackoverflow.com/a/3889630/2574125

Windows, XAMPP
视窗，XAMPP
$php = getenv('PHPRC') . '/php.exe';
if(is_file($expected)){
return $php;
}
