Interface: JsonSerializable - X-Ref

| array_replace_recursive( $base = array() X-Ref |
| PHP-agnostic version of {@link array_replace_recursive()}. The array_replace_recursive() function is a PHP 5.3 function. WordPress currently supports down to PHP 5.2, so this method is a workaround for PHP 5.2. Note: array_replace_recursive() supports infinite arguments, but for our use- case, we only need to support two arguments. Subject to removal once WordPress makes PHP 5.3.0 the minimum requirement. param: array $base Array with keys needing to be replaced. param: array $replacements Array with the replaced keys. return: array |
| is_countable( $var ) X-Ref |
| Polyfill for is_countable() function added in PHP 7.3. Verify that the content of a variable is an array or an object implementing the Countable interface. param: mixed $var The value to check. return: bool True if `$var` is countable, false otherwise. |
| is_iterable( $var ) X-Ref |
| Polyfill for is_iterable() function added in PHP 7.1. Verify that the content of a variable is an array or an object implementing the Traversable interface. param: mixed $var The value to check. return: bool True if `$var` is iterable, false otherwise. |
| _( $string ) X-Ref |
| No description |
| _wp_can_use_pcre_u( $set = null ) X-Ref |
| Returns whether PCRE/u (PCRE_UTF8 modifier) is available for use. param: bool $set - Used for testing only |
| mb_substr( $str, $start, $length = null, $encoding = null ) X-Ref |
| Compat function to mimic mb_substr(). param: string $str The string to extract the substring from. param: int $start Position to being extraction from in `$str`. param: int|null $length Optional. Maximum number of characters to extract from `$str`. param: string|null $encoding Optional. Character encoding to use. Default null. return: string Extracted substring. |
| _mb_substr( $str, $start, $length = null, $encoding = null ) X-Ref |
| Internal compat function to mimic mb_substr(). Only understands UTF-8 and 8bit. All other character sets will be treated as 8bit. For $encoding === UTF-8, the $str input is expected to be a valid UTF-8 byte sequence. The behavior of this function for invalid inputs is undefined. param: string $str The string to extract the substring from. param: int $start Position to being extraction from in `$str`. param: int|null $length Optional. Maximum number of characters to extract from `$str`. param: string|null $encoding Optional. Character encoding to use. Default null. return: string Extracted substring. |
| mb_strlen( $str, $encoding = null ) X-Ref |
| Compat function to mimic mb_strlen(). param: string $str The string to retrieve the character length from. param: string|null $encoding Optional. Character encoding to use. Default null. return: int String length of `$str`. |
| _mb_strlen( $str, $encoding = null ) X-Ref |
| Internal compat function to mimic mb_strlen(). Only understands UTF-8 and 8bit. All other character sets will be treated as 8bit. For $encoding === UTF-8, the `$str` input is expected to be a valid UTF-8 byte sequence. The behavior of this function for invalid inputs is undefined. param: string $str The string to retrieve the character length from. param: string|null $encoding Optional. Character encoding to use. Default null. return: int String length of `$str`. |
| hash_hmac( $algo, $data, $key, $raw_output = false ) X-Ref |
| Compat function to mimic hash_hmac(). param: string $algo Hash algorithm. Accepts 'md5' or 'sha1'. param: string $data Data to be hashed. param: string $key Secret key to use for generating the hash. param: bool $raw_output Optional. Whether to output raw binary data (true), return: string|false The hash in output determined by `$raw_output`. False if `$algo` |
| _hash_hmac( $algo, $data, $key, $raw_output = false ) X-Ref |
| Internal compat function to mimic hash_hmac(). param: string $algo Hash algorithm. Accepts 'md5' or 'sha1'. param: string $data Data to be hashed. param: string $key Secret key to use for generating the hash. param: bool $raw_output Optional. Whether to output raw binary data (true), return: string|false The hash in output determined by `$raw_output`. False if `$algo` |
| json_encode( $string ) X-Ref |
| No description |
| json_decode( $string, $assoc_array = false ) X-Ref |
param: string $string param: bool $assoc_array return: object|array |
| _json_decode_object_helper( $data ) X-Ref |
param: object $data return: array |
| hash_equals( $a, $b ) X-Ref |
| Timing attack safe string comparison Compares two strings using the same time whether they're equal or not. This function was added in PHP 5.6. Note: It can leak the length of a string when arguments of differing length are supplied. param: string $a Expected string. param: string $b Actual, user supplied, string. return: bool Whether strings are equal. |
| json_last_error_msg() X-Ref |
| Retrieves the error string of the last json_encode() or json_decode() call. return: bool|string Returns the error message on success, "No Error" if no error has occurred, |
