Note that there is a limitation to the maximum size of a string for a 
node.  I am submitting here in as documentation.

I have a string that is 455K in Size.  I tried creating an XML Node 
with this string as it's value, but the string always gets cut off at 
about 83K - 

I attempted using both the nodeValue property, and by creating a new 

Reproduce code:

To replicate, create a string that is greater than 83K (or so) - 

$string="text that is really big"

$node=new DOMText($string);

echo $node->wholeText;


The echo'd value will be cut off at about 83K

Expected result:
Is there a reason for the limitation? - Or, is this a bug?

Rob, can you clarify whether that's an PHP or libxml2 limitation? Thanks.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

I cannot reproduce this.
Using a script similar to what you posted, I hit no 
limitation on string length. Was easily able to write/read using a 
string 300K long. Are you able to duplicate this on other platforms as
