How to view value of long strings using NetBeans and x-debug?

Question

Is there a setting for x-debug or NetBeans to extend the maximum string size it will display?

Using NetBeans to debug PHP application in Windows, I can add a watch or hover over any variable to see its value. But for long strings, all I get is (string), no value.

Environment: Windows 7, NetBeans 7.0.1, x-debug 2.0.3-5.1.7, Apache 2.0.63, PHP 5.1.6

php.ini contains:

zend_extension_ts = c:\wamp\bin\php\php5.1.6\ext\php_xdebug-2.0.3-5.1.7.dll
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.var_display_max_data=2048

Setting xdebug.var_display_max_data to -1 seems to have fixed the problem. Hope this helps someone else.

Even if your string limits are OK in xdebug, you can still have problems in netbeans.

For this goto to Options -> PHP -> Debugging tab in netbeans and set Maximum Data Length to a large number like 100000 (I think -1 should also work here).

(Tip from https://netbeans.org/bugzilla/show_bug.cgi?id=215728#c6 )

Setting Maximum Data Length to a large number worked. Setting it to -1 caused an error in Xdebug.

Modify xdebug.var_display_max_data. The default value is 512, so bump that up to your desired length.

Thanks alex, but I tried that. Testing with a string of about 1850 bytes - I originally had xdebug.var_display_max_data=2048 and have since bumped it up to 8192, but still can't see the variable value.

@AlienTechnology Weird, not sure if I know the answer then.
