NOTE: The PHP API is not complete on 32 bit architectures. PHP
doesn't offer any convenient 64 bit type (on 32 bit). Any 64 bit
parameters or return values will be truncated to 32 bits on these
platforms. You should always use these PHP bindings on a 64 bit
operating system.
To install the extension manually, copy guestfs_php.so into the
modules directory (eg. /usr/local/lib/php/modules/) and copy
guestfs_php.ini into the config directory (eg. /etc/php.d/).
[Note: On packaged Linux distributions you don't need to do this]
The PHP API follows the C API. Refer to guestfs(3) or
http://libguestfs.org/guestfs.3.html for the details of the C API.
To create a handle, use guestfs_create() like this:
<?php
$g = guestfs_create ();
if ($g == false) {
echo ("Failed to create guestfs_php handle.\n");
exit;
}
?>
Handles are closed implicitly by the PHP dtor.
All of the usual functions from the C API are available. By
convention these return 'false' for errors, so:
<?php
//...
if (guestfs_launch ($g) == false) {
echo ("Error: ".guestfs_last_error ($g)."\n");
exit;
}
?>
or:
<?php
//...
$version = guestfs_version ($g);
if ($version == false) {
echo ("Error: ".guestfs_last_error ($g)."\n");
exit;
}
echo ("libguestfs version = ".
$version["major"].".".$version["minor"].".".$version["release"].
$version["extra"]."\n");
?>
C API structs are mapped to associative arrays. C API lists of
structs are mapped to arrays of associative arrays. Other C API
parameters and return values are mapped to natural PHP types.
