PHP utf8_encode() Functie

❮ PHP XML Parser Referentie

Voorbeeld

Codeer een ISO-8859-1 string naar UTF-8:

<?php
$text = "\xE0";
echo utf8_encode($text);
?>

Definitie en gebruik

De functie utf8_encode() codeert een ISO-8859-1-tekenreeks naar UTF-8.

Unicode is een universele standaard en is ontwikkeld om alle mogelijke tekens van alle talen te beschrijven plus een groot aantal symbolen met één uniek nummer voor elk teken/symbool.

Het is echter niet altijd mogelijk om een Unicode-teken betrouwbaar naar een andere computer over te brengen. UTF-8 is ontwikkeld om een Unicode-teken van de ene computer naar de andere over te brengen.

Syntaxis

utf8_encode(string)

Parameterwaarden

Parameter	Description
string	Required. Specifies the ISO-8859-1 string to encode

Technische details

Winstwaarde:	De gecodeerde tekenreeks bij succes. ONWAAR bij fout
PHP-versie:	4.0+
