Hi there

We are trying to write PDF, Word, JPG and other binary files to a Sybase SQL Anywhere database using PHP.

We are connecting with PHP using PHP_DBLIB through PDO and are using the code below to read and a file and write into a column:

<?php
// Read file
$filename = “/path/to/file/pdf.pdf";
$handle = fopen($filename, "rb");
$contents = fread($handle, filesize($filename));

// Attempt to write file
$query = $db->prepare('INSERT INTO table_name (id, document_blob) VALUES (1, ?)’);
$query->bindParam(1, $contents, \PDO::PARAM_LOB);
$query->execute();
?>

The whole query just fails with a generic error message, however we are able to use the above code to write to a MySQL database.

Any thoughts / inspiration gratefully received.

Cheers
Ed

Hi Ray

Thanks for getting back to me - it's much appreciated.

Unfortunately the situation does not allow us to try the things you suggest. We are building a web front-end to a legacy application and as such the encoding of documents / storing them as BLOBs are pre-determined for us.

we are still scratching our heads at this end about how to resolve this.
