Non-breaking spaces can be troublesome with trim (as per an earlier comment):
// turn some HTML with non-breaking spaces into a "normal" string
$myHTML = " abc";
$converted = strtr($myHTML, array_flip(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES)));
// this WILL NOT work as expected
// $converted will still appear as " abc" in view source
// (but not in od -x)
$converted = trim($converted);
// are translated to 0x40, so use:
$converted = trim($converted, "\xA0");
// PS: Thanks to John for saving my sanity!
