php-icap-client

PHP ICAP client.

Allows you to send requests to Internet Content Adaptation Protocol (ICAP) servers from PHP.

Usage

Instantiate the class with the ICAP server address and port:

$icap = new IcapClient('127.0.0.1', 13440);

Send an OPTIONS request to the "example" service:

$icap->options('example');

Send a REQMOD and RESPMOD request to the "example" service:

$icap->reqmod(
    'example',
    [
        'req-hdr' => "POST /test HTTP/1.1\r\nHost: 127.0.0.1\r\n\r\n",
        'req-body' => 'This is another test.'
    ]
);

$icap->respmod(
    'example',
    [
        'res-hdr' => "HTTP/1.1 200 OK\r\nServer: Test/0.0.1\r\nContent-Type: text/html\r\n\r\n",
        'res-body' => 'This is a test.'
    ]
);

Successful requests will return an array describing the response:
