xdebug.var_display_max_data doesn't work
<p>I am working on a PHP project and I want to test a string that is quite long. And I set a watch to monitor this string. However when the length of this string hits some limitation, the value of it shows "Evaluation...".</p>

<p>The following is my conf</p>

<pre><code>zend_extension = C:\xampp\php\ext\php_xdebug-2.4.0-5.6-vc11.dll
xdebug.remote_enable = On
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.var_display_max_data=-1
xdebug.var_display_max_depth=10
</code></pre>

<p>It seems that <code>xdebug.var_display_max_data=-1</code> doesn't work.</p>

<p>This problem occurs when I use substr() function. For example, <code>substr($string, 0, 2048)</code> works, but <code>substr($string, 0, 2049)</code> shows 'null'.</p>

<p>Can anyone help me? </p>

<p>Thanks</p>
