PHP extension summary // to be improved

1. PHP’s iconv extension: an interface for handling character set conversion.
The system checks that the iconv extension installed contains the character encoding set: iconv -l
Functions included in the extension module:
iconv_get_encoding()//Get iconv internal configuration information
iconv_mime_decode_headers()//Decode multiple MIME headers
iconv_mime_decode()//Decode a MIME header
iconv_mime_encode()//Compress a MIME header
iconv_set_encoding()//Set the current settings for character encoding conversion
iconv_strlen()//Count the number of characters in a string
iconv_strpos()// Finds position of first occurrence of a needle within a haystack
iconv_strrpos()//Finds the last occurrence of a needle within a haystack
iconv_substr()//Intercept part of the string
iconv()//Convert string encoding
ob_iconv_handler()//Use the buffer handler to convert the string encoding

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
