The characters inserted fine, the problem was that I’m using INSERT … ON DUPLICATE KEY UPDATE syntax to avoid looking if the field exists, so after debugging where the application was breaking I got this: Query failed: Cannot add or update a child row: a foreign key constraint fails (`trubaseek/mapKeywordName`, CONSTRAINT `fkDomainMapNameId` FOREIGN KEY (`NameId`) REFERENCES `names` (`nameId`) ON DELETE NO ACTION ON UPDATE NO ACTION)<br> SQL: INSERT INTO `mapKeywordName` (`keywordId`, `nameId`) VALUES ('1', '326'); so I’ve spent about an hour changing the encodings without success, but after some testing I discovered that hôteles was the same as hotelës, I did several testing from the linux console, the mysql browser, and from a php script, and all revealed the same.https://ivanvillareal.com/parsing-html-documents-with-simple-html-dom/Wed, 30 Sep 2009 23:02:34 +0000https://ivanvillareal.com/parsing-html-documents-with-simple-html-dom/I had to get some information from an HTML page, the information required was on nested tables, so I’ve started working on it and my first approach was to get the info needed using regular expressions. After 2 hours I’ve created a set of regex that worked pretty well, but when I received a new document, the layout was a bit different, and my regex didn’t worked as expected, the content was on the same table but this time it had nested tables, which were a really big problem.
