ibase_blob_get

ibase_blob_get

(PHP 4, PHP 5)

ibase_blob_getGet len bytes data from open blob

说明

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().

Note:

It is not possible to read from a BLOB that has been opened for writing by ibase_blob_create().

参数

A BLOB handle opened with ibase_blob_open().

len

Size of returned data.

返回值

范例

Example #1 ibase_blob_get() example

<?php
$result    
ibase_query("SELECT blob_value FROM table");
$data      ibase_fetch_object($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.
