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
The above has introduced a summary of PHP extensions // to be improved, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
