Using PHP, I set up two for loops one inside the other with a database read statement in between. This works fine for small loops but on larger loops the data just dissappears. The scipt completes without error.

 

<?php

$END=174;

$SUBJECTLIST=array("aa","bb","cc"); //Total OF 40 ELEMENTS

for ($x=0; $x < $END; ++$x)

{

for ($c=0; $c < 40; ++$c)

{

 

// OPEN DATABASE

$conn=odbc_connect('xxx','','');

if (!$conn)

  {exit("Database Connection Failed: " . $conn);}

 

$sql="SELECT * FROM $DATABASE WHERE a2='$Identity[$x]' and a11='$SUBJECTLIST[$c]'";

 

$rs=odbc_exec($conn,$sql);

if (!$rs)

  {exit("Error in $DATABASE SQL");}

 

while (odbc_fetch_row($rs))

{

 

  $NAME[$x]=odbc_result($rs,"a2");

  $Information[$x]=odbc_result($rs,"a11");

 

// Twenty other odbc_result statements

 

}// End of WHILE

 

odbc_free_result($rs);

odbc_close($conn);

 

 

// Printing out the values, the data suddenly stops. Each time varying by a couple of

// rows.

 

}

}

?>

 

Why does this occur ?

Is there a better way of coding ?

Any help please..

 

Regards,

Brian
