ibase_blob_echo — Pass a BLOB directly to output stream


boolean ibase_blob_echo(blob);
string blob: BLOB's internal ID in database

Passes a BLOB's contents directly to the output stream after sending all waiting headers. Return value is TRUE if the BLOB could be opened and all of its contents sent, otherwise FALSE.


Available in PHP 3 since 3.0.7, PHP 4 since 4.0RC1


Example 531. Output an image from database to client

// Assume that this example is saved in a file "image.php"
// and called with URL
// Suppress all errors with @ so that headers don't get sent before we want
$conn = @ibase_connect("/path/to/employees.gdb", "username", "password");
$res = @ibase_query("SELECT image, image_type FROM employees WHERE emp_id = $id");
if ($row = @ibase_fetch_row($res)) {
    header("Content-Type: $row[1]");
} else {
    // image not found in database
    header("Content-Type: image/gif");
