fbsql_create_blob — Create a BLOB
$blob_data
[, resource $link_identifier
] )Creates a BLOB from the given data.
blob_data
The BLOB data.
link_identifier
由 fbsql_connect() 或 fbsql_pconnect() 返回的 FrontBase 链接标识符.
如可选并未指定,函数会尝试查找一个到 FrontBase 服务器的开放链接,且如没有找到这样的链接,会尝试通过不带参数调用 fbsql_connect() 来创建一个。
Returns a resource handle to the newly created BLOB, which can be used with insert and update commands to store the BLOB in the database.
Example #1 fbsql_create_blob() example
<?php
$link = fbsql_pconnect ( "localhost" , "_SYSTEM" , "secret" )
or die( "Could not connect" );
$filename = "blobfile.bin" ;
$fp = fopen ( $filename , "rb" );
$blobdata = fread ( $fp , filesize ( $filename ));
fclose ( $fp );
$blobHandle = fbsql_create_blob ( $blobdata , $link );
$sql = "INSERT INTO BLOB_TABLE (BLOB_COLUMN) VALUES ( $blobHandle );" ;
$rs = fbsql_query ( $sql , $link );
?>
