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)

Requires

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)
kvlist 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.

Input and output

php-s11n-read

[procedure] (php-s11n-read [PORT])

php-s11n-write

[procedure] (php-s11n-write VALUE [PORT])
