Run PHP function inside Bash (and keep the return in a bash variable)
提问by Roger
I am trying to run a PHP function inside Bash... but it is not working.
我正在尝试在 Bash 中运行一个 PHP 函数......但它不起作用。
#! /bin/bash
/usr/bin/php << 'EOF'
<?php echo getcwd(); ?>
EOF
In the reality, I needed to keep the return value in a bash variable... By the way, I am using the php's getcwd() function only to illustrate the bash operation.
在现实中,我需要将返回值保留在bash变量中......顺便说一下,我使用php的getcwd()函数只是为了说明bash操作。
UPDATE:Is there a way to pass a variable?
更新:有没有办法传递变量?
VAR='/$#'
php_cwd=`/usr/bin/php << 'EOF'
<?php echo preg_quote($VAR); ?>
EOF`
echo "$php_cwd"
Any ideas?
有任何想法吗?

php_cwd=`/usr/bin/php << 'EOF'
<?php echo getcwd(); ?>
EOF`
echo "$php_cwd" # Or do something else with it

PHP_OUT=`php -r 'echo phpinfo();'`
echo $PHP_OUT;

Alternatively:
或者:
php_cwd = `php -r 'echo getcwd();'`
replace the getcwd(); call with your php code as necessary.
替换 getcwd(); 根据需要使用您的 php 代码调用。

This is how you can inline PHP commands within the shell i.e. *sh:
这是在 shell 中内联 PHP 命令的方法,即 *sh:
#!/bin/bash
export VAR="variable_value"
php_out=$(php << 'EOF'
<?
echo getenv("VAR"); //input
?>
EOF)
>&2 echo "php_out: $php_out"; #output

Use '-R' of php command line. It has a build-in variable that reads inputs.
使用 '-R' 的 php 命令行。它有一个读取输入的内置变量。
VAR='/$#'
php_cwd=$(echo $VAR | php -R 'echo preg_quote($argn);')
echo $php_cwd

This is what worked for me:
这对我有用:
VAR='/$#'
php_cwd=`/usr/bin/php << EOF
<?php echo preg_quote("$VAR"); ?>
EOF`
echo "$php_cwd"

I have a question - why don't you use functions to print current working directory in bash? Like:
我有一个问题 - 为什么不使用函数在 bash 中打印当前工作目录?喜欢:
#!/bin/bash
pwd # prints current working directory.
Or
或者
#!/bin/bash
variable=`pwd`
echo $variable
Edited: Code above changed to be working without problems.
编辑:上面的代码更改为可以正常工作。
