  1. POArrays values not identical (but they are?)
    text
    copied!<p>I have two arrays. They seem to contain at least one identical set of values, but performing <code>array_diff()</code> does not return anything even though I think it should! This should have been just routine code but for some reason it's not liking what I've done.</p> <p>The weird thing is that <code>var_dump($queue[0]);</code> returns <code>String(167);</code> and <code>var_dump($videos[0])</code> returns <code>String(168)</code>.</p> <p>So clearly, they must be different right?</p> <p><code>echo similar_text($queue[0]), $videos[0]);</code> returns <code>167</code>. What!?</p> <p><strong>Note: These are just file names and do not represent the contents of the file.</strong></p> <p><strong>Videos Array</strong></p> <p><code>Array ( [0] =&gt; /var/www/downloads/j2/Dexter Season 1, 2, 3, 4, 5 &amp; 6 + Extras (Early Cuts, Audiobooks etc) DVDRip HDTV TSV/Season 3/Dexter Season 3 Episode 04 - All in the Family.avi )</code></p> <p><strong>Queue Array</strong></p> <p><code>Array ( [0] =&gt; /var/www/downloads/j2/Dexter Season 1, 2, 3, 4, 5 &amp; 6 + Extras (Early Cuts, Audiobooks etc) DVDRip HDTV TSV/Season 3/Dexter Season 3 Episode 04 - All in the Family.avi [1] =&gt; j2 )</code></p> <p><strong>Outputs</strong></p> <p><code>$diff = array_intersect($queue,$videos); print_r($diff);</code> <em>returns</em> <code>Array ( )</code></p> <p><code>var_dump($queue[0]);</code> returns <code>string(167) "/var/www/downloads/j2/Dexter Season 1, 2, 3, 4, 5 &amp; 6 + Extras (Early Cuts, Audiobooks etc) DVDRip HDTV TSV/Season 3/Dexter Season 3 Episode 04 - All in the Family.avi"</code></p> <p><code>var_dump($videos[0]);</code> <em>returns</em> <code>string(168) "/var/www/downloads/j2/Dexter Season 1, 2, 3, 4, 5 &amp; 6 + Extras (Early Cuts, Audiobooks etc) DVDRip HDTV TSV/Season 3/Dexter Season 3 Episode 04 - All in the Family.avi"</code></p> <p><code>echo similar_text($queue[0], $videos[0]);</code> <em>returns</em> <code>167</code>.</p> <p>I've put the strings into JavaScript character counts, I've used strlen(), trim() to trim whitespace, I've even manually counted each character individually. What's going on?</p>
