This function returns a connection resource on success, zero on
failure.
yaz_connect() prepares for a connection to a
Z39.50 server. The zurl argument takes the form
host[:port][/database]. If port is omitted, port 210 is used. If
database is omitted Default is used.
This function is non-blocking and does not attempt to establish
a connection - it merely prepares a connect to be performed later when
yaz_wait() is called.
If the second argument, options, is given as
a string it is treated as the Z39.50 V2 authentication string
(OpenAuth).
If options is given as an array the contents
of the array serves as options. Note that array options are only
supported for PHP 4.1.0 and later.
yaz_connect() options
user
Username for authentication.
group
Group for authentication.
password
Password for authentication.
cookie
Cookie for session (YAZ proxy).
proxy
Proxy for connection (YAZ proxy).
persistent
A boolean. If TRUE the connection is persistent; If FALSE
the connection is not persistent. By default connections are persistent.
piggyback
A boolean. If TRUE piggyback is enabled for searches; If
FALSE piggyback is disabled. By default piggyback is enabled. Enabling
piggyback is more efficient and usually saves a network-round-trip for
first time fetches of records. However, a few Z39.50 servers do not
support piggyback or they ignore element set names. For those, piggyback
should be disabled.
charset
A string that specifies character set to be used
in Z39.50 language and character set negotiation.
Use strings such as:
ISO-8859-1, UTF-8,
UTF-16.
Most Z39.50 servers do not support this feature (and thus,
this is ignored). Many servers use the ISO-8859-1
encoding for queries and messages. MARC21/USMARC records are not
affected by this setting.
Note:
The YAZ proxy is a
freely available Z39.50 proxy.
