ibase_blob_echo
(PHP 3>= 3.0.7, PHP 4 )
ibase_blob_echo -- Output blob contents to browser
Description
bool ibase_blob_echo ( string blob_id)
This function opens a BLOB for reading and sends its contents
directly to standard output (the browser, in most cases).
Returns TRUE on success or FALSE on failure.
See also ibase_blob_open(), ibase_blob_close() and ibase_blob_get().
ibase_blob_get
(PHP 3>= 3.0.7, PHP 4 )
ibase_blob_get -- Get len bytes data from open blob
Description
string ibase_blob_get ( resource blob_handle, int len)
This function returns at most len bytes from a BLOB that
has been opened for reading by ibase_blob_open(). Returns
FALSE on failure.
<?php
$sql = "SELECT blob_value FROM table";
$result = ibase_query($sql);
$data = ibase_fetch_object($result);
$blob_data = ibase_blob_info($data->BLOB_VALUE);
$blob_hndl = ibase_blob_open($data->BLOB_VALUE);
echo ibase_blob_get($blob_hndl, $blob_data[0]);
?>
Whilst this example doesn't do much more than a 'ibase_blob_echo($data->BLOB_VALUE)'
would do, it does show you how to get information into a
$variable to manipulate as you please.
Note: It is not possible to read from a BLOB that has been
opened for writing by ibase_blob_create().
