Previous Comments: ------------------------------------------------------------------------ [2008-11-15 11:40:57] j at ww dot com Description: ------------ There is a nasty little gotcha in 'strip_tags', if you have a single quote inside an html comment strip_tags will ignore the end-of-comment tag! So, <!-- test --> this works, but <!-- test I've --> this does not, the end-of-comment tag will be ignored. Reproduce code: --------------- $i = "<!-- testing I've been to mars --> quite so"; echo(strip_tags($i)); Expected result: ---------------- It should read "quite so", instead it returns a blank string, presumably because no end quote was encountered (the parser has probably switched into 'attribute' mode, but in a comment there are no attributes). Adding another quote to the above example will verify this hypothesis. Actual result: -------------- an empty string. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46578&edit=1
