The following code:
<?php
$conn = odbc_connect("DSN=*LOCAL", null, null);
var_dump($conn);Resulted in this output:
bool(true)
But I expected this output instead:
PHP Warning: odbc_connect(): SQL error: [unixODBC][Driver Manager]Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in /home/calvin/src/test-heuristic.php on line 3
bool(false)
The ODBC drivers use strchr(db/dsn, ";") (well, procedural uses strstr, but same deal) to detect if the string the user passed into the constructor is a connection string or not. However, this isn't accurate for connection strings with a single entity (i.e. a DSN=dsn - seems useless versus just using the DSN name, but valid and still useful if you're i.e. building a connection string programatically).
One solution might be to use the ODBC quoting rules like in my PR #8307, but there's valid DSNs that use the characters that Microsoft claims have to require quoting. For example, IBM's Db2 for i driver installs a *LOCAL DSN in odbc.ini (on IBM i versions of the driver for loopback, but the point remains, can i.e. easily just add a DSN of that name to your own system), which would make the simple DSN name case invalid for that DSN.
Another solution is to just scan for a subset of those characters - = might be enough to add, or instead of ;.
