<h3 class="title">Calls from incompatible context</h3>
<p class="para">
Methods called from an incompatible context are now deprecated, and will
generate <strong><code>E_DEPRECATED</code></strong> errors when invoked instead of
<strong><code>E_STRICT</code></strong>. Support for these calls will be removed in
a future version of PHP.
</p>
<p class="para">
An example of such a call is:

<p class="para">The above example will output:</p>

<p class="para">
<a href="ini.core.html#ini.always-populate-raw-post-data" class="link">always_populate_raw_post_data</a>

<var class="varname"><var class="varname"><a href="reserved.variables.httprawpostdata.html" class="classname">$HTTP_RAW_POST_DATA</a></var></var> is populated.
New code should use
<a href="wrappers.php.html#wrappers.php.input" class="link"><em>php://input</em></a>
instead of <var class="varname"><var class="varname"><a href="reserved.variables.httprawpostdata.html" class="classname">$HTTP_RAW_POST_DATA</a></var></var>, which will be removed
in a future release. You can opt in for the new behaviour (in which
<var class="varname"><var class="varname"><a href="reserved.variables.httprawpostdata.html" class="classname">$HTTP_RAW_POST_DATA</a></var></var> is never defined hence no
<strong><code>E_DEPRECATED</code></strong> error will be generated) by setting
<a href="ini.core.html#ini.always-populate-raw-post-data" class="link">always_populate_raw_post_data</a>
to <em>-1</em>.
