We have migrated from a unix solaris server to a linux server. When we run the same pieces of code, they are behaving very differently. Some of the problems I am facing are -
cat filename | read var1 var2
echo "var1 var2"
works in unix, but returns null values in linux.
interesting.... what do you on Solaris?
First, echo have
where you probably meant:
besides the above, this will not return anything as you're PIPING to 'read' which creates a subshell which exits after the 'read' is done and your var1/var2 vanish as well.

Your $PATH env var probably does not include the directory where 'compress' resides on linux (if it's installed at all).

Thanks for your time!
Take a look at this OS comparison chart, but your problems are much more shell fundamental....

CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.0.3 | |
| | |
| | get_class_vars(3) will only return the properties |
| | that can be accessed from the current scope. |
| | |
| 5.0.2 | |
| | |
| | Calling get_class_vars(3) will now expose all |
| | the properties as an array, unlike previous be- |
| | haviour where protected and private properties |
| | were prefixed with nul bytes. |
| | |
| 5.0.1 | |
| | |
| | Calling get_class_vars(3) will expose all prop- |
| | erties, as when converting an object to a class. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
get_class_vars(3) example
<?php
class myclass {
var $var1; // this has no default value...
var $var2 = "xyz";
var $var3 = 100;
private $var4;
// constructor
function myclass() {
// change some properties
$this->var1 = "foo";
$this->var2 = "bar";
return true;
}
}
$my_class = new myclass();
$class_vars = get_class_vars(get_class($my_class));
foreach ($class_vars as $name => $value) {
echo "$name : $value
";
}
?>
The above example will output:
var1 :
var2 : xyz
var3 : 100
Example #2
get_class_vars(3) and scoping behaviour
<?php
function format($array)
{
return implode('|', array_keys($array)) . "
";
}
class TestCase
{
public $a = 1;
protected $b = 2;
private $c = 3;
public static function expose()
{
echo format(get_class_vars(__CLASS__));
}
}
TestCase::expose();
echo format(get_class_vars('TestCase'));
?>
The above example will output:
// 5.0.0
a| * b| TestCase c
a| * b| TestCase c
// 5.0.1 - 5.0.2
a|b|c
a|b|c
// 5.0.3 +
a|b|c
a
