Bug description: CVS function var_export() can't handle recursive arrays
The problem is similar to var_dump(). var_dump() is fixed by Yasuo today
but another one raised (see Bug#16065)
var_export() has to handle recursive dependencies better and the fatal
error is not an option.
Here is the script:
<?php
$a=array();
$a[]=&$a;
var_export($a);
?>
and the ouput:
bash-2.04$ ../php export.php
X-Powered-By: PHP/4.3.0-dev
Content-type: text/html
array (
0 =>
array (
0 =>
array (

PHP Fatal error: Nesting level too deep - recursive dependency? in
/usr/samba/users/andy/412dev/php4-200203140300/te/export.php on line 4
<br />
<b>Fatal error</b>: Nesting level too deep - recursive dependency? in
<b>/usr/samba/users/andy/412dev/php4-200203140300/te/export.php</b> on
line <b>4</b><br />
Possible fix is another parameter(string) with var_export()-ed variable
name - this will fix if the array has element which is reference to the
array but will not handle this :
<?php
$a=array(1,2);
$a[]=&$a;
$b=array(&$a,3,4);
var_export($a);
?>
that crashes with output :
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 1,
1 => 2,
2 =>
