Приклад #1 map example
<?php
$convmap = array(
int start_code1, int end_code1, int offset1, int mask1,
int start_code2, int end_code2, int offset2, int mask2,
// ........
int start_codeN, int end_codeN, int offsetN, int maskN
);
// Specify Unicode value for start_codeN and end_codeN
// Add offsetN to value and take bit-wise 'AND' with maskN,
// then converts value to numeric string reference.
?>
Приклад #2 mb_encode_numericentity() example
<?php
$str = "aAæÆあア𩸽";
/* Convert all UTF8 characters up to 4 bytes to HTML numeric character reference */
$convmap = [0, 0x1FFFFF, 0, 0x10FFFF];
var_dump(mb_encode_numericentity($str, $convmap, "utf8"));
/* Converts only 2-byte and 4-byte UTF8 characters to HTML numeric character reference */
$convmap = [
0x80, 0x7FF, 0, 0x10FFFF,
0x10000, 0x1FFFFF, 0, 0x10FFFF,
];
var_dump(mb_encode_numericentity($str, $convmap, "utf8"));
?>Поданий вище приклад виведе:
string(46) "aAæÆあア鸽" string(28) "aAæÆあア鸽"
