heroku上的php路径在exec中不起作用

标签: php heroku path exec

我在Heroku上有一些PHP应用程序。当我启用PHP时,我也运行此命令,I've found somewhere at Stackoverflow

heroku config:add LD_LIBRARY_PATH=/app/php/ext:/app/apache/lib
Setting config vars and restarting zfq... done, v7
LD_LIBRARY_PATH: /app/php/ext:/app/apache/lib

命令行中的这个命令工作正常:

heroku run ./php/bin/php -v
Running `./php/bin/php -v` attached to terminal... up, run.3208
PHP 5.3.10 (cli) (built: Mar 26 2012 08:15:52)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies

但是这段代码:

$nickname = $_POST['nickname'];
$filename = "1.txt";
$cmd      = './php/bin/php -v > "' . $filename . '" 2>&1 &';

exec($cmd, $output);
$contents = file_get_contents($filename);
unlink($filename);

exit_ajax($contents);

返回sh: ./php/bin/php: not found

如果我将 ./ php / bin / php 更改为〜/ php / bin / php - 它会返回false

./ php - 返回sh: ./php: not found

工作正常

$cmd = "/app/php/bin/php -v " ...

使用 / app / php / bin / php 而非 ./ app / php / bin / php

两者都不一样,因为后者会搜索文件根目录中的/ app文件夹,即/ app / www /,因此在/ app / www /

中找不到app文件夹
