Passing variables from bash to php-cli
Hello everyone,

I've been looking how to pass variables between bash and php-cli in 1 file. So far i got this:

Code:
#!/bin/bash
echo "This is bash"

php << EOF
<?php
echo "This is php\n";
?>
EOF

I would now like to be able to pass a variable declared in the bash to the php. I already figured out i can split it in 2 files and get the variable in php with $argv, but i would really like my script to be 1 file.

Thanks in advance

Just managed to answer my own question. For those wondering:

bash: export VAR="value"
php: getenv("VAR");

ok next problem... i can't seem to declare any variables in the php.
Code:
#!/bin/bash
echo "This is bash"
export VAR="blabla"

/usr/bin/php -q << EOF
<?php

echo getenv("VAR");

?>
EOF

works good, while this doesn't work:

Code:
#!/bin/bash
echo "This is bash"
export VAR="blabla"

/usr/bin/php -q << EOF
<?php

$var = getenv("VAR");
echo $var;

?>
EOF

i get this error: PHP Parse error: syntax error, unexpected '=' in - on line 3

chown

CHOWN(3)								 1								  CHOWN(3)

chown - Changes file owner

SYNOPSIS

       bool chown (string  $filename, mixed  $user)

DESCRIPTION

	Attempts to change the owner of the file $filename to user $user. Only the superuser may change the owner of a file.

PARAMETERS

	      o $filename
		- Path to the file.

	      o $user
		- A user name or number.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Simple chown(3) usage

	      <?php

	      // File name and username to use
	      $file_name= "foo.php";
	      $path = "/home/sites/php.net/public_html/sandbox/" . $file_name ;
	      $user_name = "root";

	      // Set the user
	      chown($path, $user_name);

	      // Check the result
	      $stat = stat($path);
	      print_r(posix_getpwuid($stat['uid']));

	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [name] => root
		  [passwd] => x
		  [uid] => 0
		  [gid] => 0
		  [gecos] => root
		  [dir] => /root
		  [shell] => /bin/bash
	      )

NOTES

       Note

	      This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

       Note

	      When  safe  mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script
	      that is being executed.
