That speed! ODBC is slower, the driver is older and, especially,
corrupts the index file (cdx) on deletes

Ups! Please replace $this->recordset by $recordset (copy/paste error;)

Well, not sure I can even debug that as I see no way to have the VFP
data.

But why do you use COM and ADODB instead of ODBC? ODBC will be way more
stable than ADODB through COM.

<?php

$charPage = CP_UTF8;
$stringDeConexion = 'Provider=VFPOLEDB.1;Data
Source="\\server\data";Mode=ReadWrite|Share Deny
None;Password="";Collating Sequence=SPANISH;DELETED=False';
$cantRegAfectados = -1;
$consulta = 'SELECT * FROM hugedbf1 x INNER JOIN hugedbf2 y ON
x.Id=y.xId';
$conexion = null;
$rs = null;
$comando = null;
# intenta crear el objeto y conectarse
try {
  $conexion = new COM("ADODB.Connection", null, $charPage);
  $conexion->ConnectionTimeout = 1200;
  $conexion->CommandTimeout = 2400;
  $conexion->Open($stringDeConexion);
}
catch (Exception $e) {
  echo "Error creando conexion OLEDB.<br/><br/>". $e->getMessage();
  exit(1);
} 
# intenta crear un comando
try {
  $comando = new COM("ADODB.Command");
  $comando->CommandType = 1; //adCmdText
  $comando->ActiveConnection = $conexion;
  $comando->CommandText = $consulta;
}
catch (Exception $e) {
  echo "Error creando el comando OLEDB.<br/><br/>". $e->getMessage();
  exit(1);
} 
# intenta ejecutar el comando SQL
try {
  $rs = $comando->Execute($cantRegAfectados);
}
catch (Exception $e) {
  echo "Error ejecutando comando OLEDB.<br/><br/>". $e->getMessage();
  exit(1);
}
# pasa los datos al recordset y libera los recursos
$this->recordset = array();
$j=0;
if ($rs->State!=0) {
  while (!$rs->EOF) {
    for ($i=0; $i<$rs->Fields()->Count; $i++) {
      $this->recordset[$j][$rs[$i]->Name] = $rs[$i]->Value;
    }
    $rs->MoveNext();
    $j++;
  }
  $rs->Close();
}
$conexion->Close();
$rs = null;
$conexion = null;
echo "It's all right!";
return 0;

?>

PD: You will need hugedbf1.dbf and hugedbf2.dbf shared on \\server\data
and the user running apache service need permission from I/O there.
Also
you have to have installed the VFP OLEDB drivers.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Description:
------------
I thought it might be a matter of server version so initially I started
a report here (http://www.apachelounge.com/viewtopic.php?p=15696) which
will be of help to avoid writing both.


Test script:
---------------
In the previous url I have posted some php code... You can use a
connection string like this for testing:

$cnStr = 'Provider=VFPOLEDB.1;Data
Source="\\server\data";Mode=ReadWrite|Share Deny
None;Password="";Collating Sequence=SPANISH;DELETED=False';

Other variables needed:

$charPage = CP_UTF8;
$consulta = "SELECT * FROM hugedbf1 x INNER JOIN hugedbf2 y ON
x.Id=y.xId"

And it's all... works fine for a few records but crash for many.

As I said in the other post, works fine with PHP 5.2

Expected result:
----------------
array results

Actual result:
--------------
php5ts.dll crash
