Description:
------------
Here is the problem, I was able to narrow the problem down to PHP ODBC, but I am still not sure why. Specifically ODBC_exec not returning data properly, but only in the case  where there is text field or combination of text and number, etc as bellow. It works with number, date, time, timestamp alone, not text alone. The data will eventaully be returned but only last 32 records from any # of records, and it takes for ever. I mean sometimes with doing simple select on few thousand records is taking 5-10 mins. 


run: 
/opt/php5.1.2/bin/php test.php

You will need:
Mac OS X
PHP 5.1.2
Apache 2.2.0 (well command line is a problem as well, so no need for apache)
iODBC 3.52.4

Oh yea on db side of things Mac OS X filemaker server w/odbc drivers. I am willing to provide dev server access and/or test it.  

Reproduce code:
---------------
<?php

putenv("DYLD_LIBRARY_PATH=/opt/libiodbc-3.52.4/lib");
putenv("ODBCINSTINI=/Library/ODBC/odbcinst.ini");
putenv("ODBCINI=/Library/ODBC/odbc.ini");

//$qry = "SELECT test FROM Person";  // test filed has text

// I limited this so it is readable
$qry = "SELECT PersonID, test FROM Person where PersonID>1 AND PersonID<100";
print $qry;

$conn = odbc_connect("Person", "username", "password");

$queryresult=odbc_exec($conn,$qry);
odbc_result_all($queryresult,1);
odbc_close($conn);

?>

Expected result:
----------------
SELECT PersonID, test FROM Person where PersonID>1 AND PersonID<100SQLNumResultCols
SQLNumResultCols
<table 1 ><tr><th>PersonID</th><th>test</th></tr>
<tr><td>1</td><td>hello</td></tr>
//... I did not want to copy all the data in here, but basically it just gets id's and text. 
<tr><td>67</td><td>hello</td></tr>
<tr><td>68</td><td>hello</td></tr>
<tr><td>69</td><td>hello</td></tr>
<tr><td>70</td><td>hello</td></tr>
<tr><td>71</td><td>hello</td></tr>
<tr><td>72</td><td>hello</td></tr>
<tr><td>73</td><td>hello</td></tr>
<tr><td>74</td><td>hello</td></tr>
<tr><td>75</td><td>hello</td></tr>
<tr><td>76</td><td>hello</td></tr>
<tr><td>77</td><td>hello</td></tr>
<tr><td>78</td><td>hello</td></tr>
<tr><td>79</td><td>hello</td></tr>
<tr><td>80</td><td>hello</td></tr>
<tr><td>81</td><td>hello</td></tr>
<tr><td>82</td><td>hello</td></tr>
<tr><td>83</td><td>hello</td></tr>
<tr><td>84</td><td>hello</td></tr>
<tr><td>85</td><td>hello</td></tr>
<tr><td>86</td><td>hello</td></tr>
<tr><td>87</td><td>hello</td></tr>
<tr><td>88</td><td>hello</td></tr>
<tr><td>89</td><td>hello</td></tr>
<tr><td>90</td><td>hello</td></tr>
<tr><td>91</td><td>hello</td></tr>
<tr><td>92</td><td>hello</td></tr>
<tr><td>93</td><td>hello</td></tr>
<tr><td>94</td><td>hello</td></tr>
<tr><td>95</td><td>hello</td></tr>
<tr><td>96</td><td>hello</td></tr>
<tr><td>97</td><td>hello</td></tr>
<tr><td>98</td><td>hello</td></tr>
<tr><td>99</td><td>hello</td></tr>
</table>

Actual result:
--------------
Notice the number and text do not work either, number alone does work.

One quick note:

I have come to belive this is some kind of buffer problem. I see that some data comes through when i do netstat -atn | grep 2399 (odbc port). It is infreequent, and in very small chunks. I think the text fields in fm db are quite large, perhaps blobs.
