PHP | iconv() Function
The iconv() function is an inbuilt function in PHP which is used to convert a string to requested character encoding. The iconv() is an international standard conversion application command-line programming interface which converts different character encodings to other encoding types with the help of Unicode conversion.
The converted module string represented by a local character set or by another character set, which is Unicode character set or other supported character set depend on the iconv implementation on the system.
Syntax:
string iconv ( string $input_charset, string $output_charset, string $str )
Parameters: This function accepts three parameters as mentioned above and described below:
- $input_charset : It is mandatory parameter used to take input characters string set.
- $output_charset : If you append the string // TRANSLIT to out_charset transliteration is activated. This means that when a character can’t be represented in the target charset, it can be approximated through one or several similarly looking characters. If you append the string // IGNORE, characters that cannot be represented in the target charset are silently discarded. Otherwise, E_NOTICE is generated and the function will return FALSE.
- $str: The required string which to be converted.
Return Value: If a string is successfully converted into requested character encoding then it returns the converted string, otherwise, return FALSE.Examples:
Input : $str = "EURO symbol '€'";
Output : Original :EURO symbol '€'
TRANSLIT :EURO symbol 'EUR'
IGNORE :EURO symbol ''
PLAIN :
Input : $str = "Indian rupees '₹'";
Output : Original :Indian rupees '₹'
TRANSLIT :Indian rupees 'INR'
IGNORE :Indian rupees ''
PLAIN :

Program 1:
php
<?php // Illustrate the iconv() function in php // Input string in Indian Rupees Symbol $str = "Indian Rupees '?' "; Â
// Print original string echo 'Original :', ("$str"), PHP_EOL; Â
// Print translating string echo 'TRANSLIT :', iconv( "UTF-8", "ISO-8859-1//TRANSLIT", $str), PHP_EOL; Â
// Print ignoring symbol echo 'IGNORE :', iconv("UTF-8", Â "ISO-8859-1//IGNORE", $str), PHP_EOL; Â
// Print plain symbol echo 'PLAIN :', iconv("UTF-8", Â Â "ISO-8859-1", $str), PHP_EOL; ?> |
Output:
Original :Indian rupees '₹' TRANSLIT :Indian rupees 'INR' IGNORE :Indian rupees '' PLAIN :
