Introduction
This egg provides serialization/unserialization of objects in a format compatible with PHP. This can be useful for communicating with PHP applications over a socket connection, or for reading and writing serialized data from files or SQL columns.
Examples
Serializing to PHP format
TODO
#;1> (use php-s11n) #;2> (php-serialize #t) "b:1;" #;3> (php-serialize 3.1415) "d:3.1415;" #;4> (php-serialize '#("a" "b" "c")) "a:3:{i:0;s:1:\"a\";i:1;s:1:\"b\";i:2;s:1:\"c\";}" #;5> (php-serialize '(first_name: "Random" last_name: "Hacker")) "a:2:{s:10:\"first_name\";s:6:\"Random\";s:9:\"last_name\";s:6:\"Hacker\";}" #;6> (php-serialize (void)) "N;"
Unserializing from PHP format
TODO
#;1> (use php-s11n) #;2> (php-unserialize "a:3:{i:1;s:1:\"a\";i:2;s:1:\"b\";i:3;s:1:\"c\";}") ((1 . "a") (2 . "b") (3 . "c")) #;3> (php-unserialize (php-serialize '(a: orange b: banana c: apple))) (("a" . "orange") ("b" . "banana") ("c" . "apple")) #;4> (php-unserialize (php-serialize '#(1 2 3 5 8 13 21 34))) #(1 2 3 5 8 13 21 34)

Serialization and unserialization
PHP's native data types are rather limited, meaning that only basic Scheme values can be serialized into and from this format. Scheme values are mapped to PHP format as follows:
Scheme | PHP |
---|---|
void | NULL |
boolean | boolean |
integer | integer (32-bit signed) |
flonum | float (64-bit) |
string | string |
character | string |
symbol | string |
vector | array (numerically indexed) |
alist | array (associative) |
hash-table | array (associative) |
N/A | object |
php-serialize
[procedure] (php-serialize VALUE)
Returns a serialized string representation of VALUE.
php-unserialize
[procedure] (php-unserialize STRING)
Converts the serialized STRING into a value.
