For instance, if you want to use a string as part of a URL but need to make it safe for that kind of use.
function replace_accents($str) {
$str = htmlentities($str, ENT_COMPAT, "UTF-8");
$str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde);/','$1',$str);
return html_entity_decode($str);
}
Or you just use the functions that are already implemented in PHP ><
the $unsafe value pulled through urlencode gives you this: “Hello%20Dani%C3%ABl”
That are all valid characters inside a URL. It even works on so called multi byte characters, which are used in Korean, Japanese, Mandarin and similar languages. I found that out the hard way when some survey system started chopping up comments.
The JavaScript equivalent is encodeURI / encodeURIComponent and to reverse that you use decodeURI / decodeURIComponent.
function replace_bishnoi($str) {
$str = htmlentities($str, ENT_COMPAT, “UTF-8”);
$str = preg_replace(‘/&([a-zA-Z])(uml|acute|grave|circ|tilde);/’,’$1′,$str);
return html_entity_decode($str);
}
The go the other way around, when facing encoded characters, you might want to get the character that relates the most to an accented variant. E.g.: You want to store a song with DJ Tiësto in the title, but want it to turn out like DJ Tiesto when creating a filename in your script.
Since this get’s encoded like we don’t want it to, here’s a link to the source: http://lievheid.nl/examples/decode_ascii/index.phps
the original snippet doesn’t cut it. Unicodes that aren’t covered by htmlentities() are ignored altogether. If you (safely) want to transform an UTF-8 string to alph-anumeric for the use in URLs, give urlify() a shot.
I have done this :
function replace_accents($str) {
$str = htmlentities($str);
$str = preg_replace(‘/&([a-zA-Z])(uml|acute|grave|circ|tilde|cedil|elig|ring|th|slash|zlig|horn);/’,’$1′,$str);
return html_entity_decode($str);
}
function replace_accents($str) {
$str = htmlentities($str);
$str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|cedil|elig|ring|th|slash|zlig|horn);/','$1',$str);
return html_entity_decode($str);
}
Thx !!
