PHP Pervasive SQL connection - php

Question

I am connecting PHP to Pervasive SQL and the connection keep resetting
This connection is on Windows Server 2012 using PHP7 on Apache 2.4. I have already created a DNS connection and the test can connect to the database successfully.
<?php
$conn=odbc_connect("brps","","");
if(!$conn) die("Could not connect");
?>

Answer 1

The following code works for me in an x64 environment using PHP 7.31 with the ODBC extension enabled in the PHP.INI. I'm also using the v11.30 x64 Client connecting to a remote PSQL v11 server.
<?php
$conn=odbc_connect("brpp","","");
if(!$conn) die("Could not connect");
$result = odbc_tables($conn);
echo '<div id="top">..</div><table border="1" cellpadding="5"><tr>';
$tblRow = 1;
while (odbc_fetch_row($result)){
if(odbc_result($result,"TABLE_TYPE")=="TABLE"){
$tableName = odbc_result($result,"TABLE_NAME");
echo '<tr><td>' . $tblRow . '</td><td>' . $tableName . '</td></tr>';
$tblRow++;
}
}
echo '</table><hr>';
$result = odbc_tables($conn);
while (odbc_fetch_row($result)){
if(odbc_result($result,"TABLE_TYPE")=="TABLE"){
$tableName = odbc_result($result,"TABLE_NAME");
echo '<div id="' . $tableName . '"> *** ' . $tableName . ' *** top</div>';
$cols = odbc_exec($conn, "SELECT * FROM $tableName WHERE 1=2");
$ncols = odbc_num_fields($cols);
for ($n=1; $n<=$ncols; $n++) {
$field_name = odbc_field_name($cols, $n);
echo $field_name . "<br>";
}
echo '<hr>';
}
}
?>
If the DSN doesn't exist, I get an error:
Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in C:\Wnmp\html\phpodbc.php on line 2
Could not connect
I was getting a System error 998 after installing the PSQL x64 client. A reboot of the machine fixed that error.
