    copied!<p>Can you tell me your opinion of this, and possibly see if you can recreate it:</p> <p>Currently, the $post->post_content variable contains:</p> <pre><code>"before &lt;img src="/path/to/valid_img.gif" /&gt; after" </code></pre> <p>This code placed at the top of the theme header.php...</p> <pre><code>------ Code -------- 1: $str = $post-&gt;post_content; 2: assert( isset( $str ) ); 3: assert( is_string( $str ) ); 4: echo $str; 5: $str = 'before &lt;img src="/path/to/nonexistant.gif" /&gt; after'; 6: assert( isset( $str ) ); 7: echo $str; -------------------- </code></pre> <p>Outputs this...</p> <pre><code>------ Output ------ before &lt;img src="/path/to/valid_img.gif" /&gt; after before &lt;img src="/path/to/nonexistant.gif" /&gt; after -------------------- </code></pre> <p>With these warnings...</p> <pre><code>--- PHP Warnings --- PHP Warning: assert() [&lt;a href='function.assert'&gt;function.assert&lt;/a&gt;]: Assertion failed in /path/to/header.php on line 2 PHP Warning: assert() [&lt;a href='function.assert'&gt;function.assert&lt;/a&gt;]: Assertion failed in /path/to/header.php on line 3 -------------------- </code></pre> <p>Why would line 4 properly echo the $str if assert() fails twice when I KNOW 100% it should succeed?</p> <p>What does a broken image src have to do with setting or unsetting the variable $str? WordPress bug/oddity?</p> <p><strong>Now the crazy part...</strong></p> <p>When lines 5-7 are commented out, thus eliminating the nonexistant.gif, the assert() warning does NOT appear and the output STILL properly produces this...</p> <pre><code>------ Output ------ before &lt;img src="/path/to/valid_img.gif" /&gt; after -------------------- </code></pre> <p>Any chance you can reproduce this and tell me what you think? I'm new to PHP, but I'm pretty sure this is crazyness. :)</p>
