PHP iconv_strlen function显示问题

Question

In the code below I'm trying to get the bytes for the characterこwhich should be 3 for the first function but I keep getting the value of 1 for each iconv_strlen function below. How can I figure out why this is?

Here is the code:

echo iconv_strlen("こ") . '<br />';
echo iconv_strlen("こ", "UTF-8") . '<br />';

Answer 1

Correct value in first case is 1, not 3.
If you want to get count of bytes, you can use strlen() function, or change iconv.internal_encoding directive in php.ini or by ini_set() (to ISO-8859-1 ) - but it will affect all iconv -functions, so I recommend to use strlen() .
