Description:
------------
In ibm_driver.c, around line 985:


+#if PHP_MAJOR_VERSION >= 7
+                        if (Z_TYPE(data) == IS_STRING) {
+#else  
                        if (Z_TYPE_PP(data) == IS_STRING) {
+#endif
                                option_str = Z_STRVAL_PP(data);
                        } else {


The opt_str = Z_STR_PP(data) after the endif fails on php 7.  The module compiles, but when I include the module in php.ini, there is an error when running php 7:  "undefined symbol: Z_STRVAL_PP" and the pdo_ibm module will not load.



Test script:
---------------
I tried replacing with:  

#if PHP_MAJOR_VERSION >= 7
                        if (Z_TYPE(data) == IS_STRING) {
                              option_str = Z_STRVAL_P(*data);

#else
                        if (Z_TYPE_PP(data) == IS_STRING) {
                               option_str = Z_STRVAL_PP(data);

#endif
                        } else {


And in this case the module loads without that error, but not sure if it is correct.  It seems definitely must not have the Z_STRVAL_PP after the endif or it will still load in php version >= 7.

Experiencing same problem.
I can get the code to compile using:

#if PHP_MAJOR_VERSION >= 7
                        if (Z_TYPE(data) == IS_STRING) {
                              option_str = Z_STRVAL_P(*data);

#else
                        if (Z_TYPE_PP(data) == IS_STRING) {
                               option_str = Z_STRVAL_PP(data);

#endif
                        } else {

but then this causes segmentation fault... executing on the cli or in Apache

Script:
<?php
try
{
    $db= new PDO("ibm:DATABASE=GEN1;HOSTNAME=10.78.10.16;PORT=50000;", "admin", "bluebird456", array(PDO::ATTR_CASE=> PDO::CASE_NATURAL));
}
catch(PDOException $e)
{
	die("Connection error: ".$e->getMessage());
}

$attributes = array(
    "AUTOCOMMIT", "ERRMODE", "CASE", "CLIENT_VERSION", "CONNECTION_STATUS",
    "ORACLE_NULLS", "PERSISTENT", "PREFETCH", "SERVER_INFO", "SERVER_VERSION",
    "TIMEOUT"
);

foreach ($attributes as $val) {
    echo "PDO::ATTR_$val: ";
    echo $db->getAttribute(constant("PDO::ATTR_$val")) . "\n";
}

?>

Possibly the segfault is related to Bug #72424...

I was able to successfully connect using "fred's" test script if I removed the options parameter from the connection string

$db= new PDO("ibm:DATABASE=$database;HOSTNAME=$hostname;PORT=$port;", $user, $password);

But also get the segfault when I add options to end of the PDO array.

Indeed without the options parameter from the connection string I can connect as well! Good catch :-)

Unfortunately, this is far from the only bug in PDO_IBM's PHP7 implementation.  While I could apply your patch, there's no way the extension will actually function in PHP 7 or later as is.

As such I'd recommend contacting the package maintainer which is opendev@us.ibm.com according to https://pecl.php.net/package/PDO_IBM

See a workaround: ( pdo_ibm 1.3.5 ) ibm_driver.c:



980 #if PHP_MAJOR_VERSION >= 7
981                         if (Z_TYPE_P(data) == IS_STRING) {
982 #else	
983 			if (Z_TYPE_PP(data) == IS_STRING) {
984 #endif
985 				option_str = Z_STRVAL_PP(data); // <--- this line
986 			} else {
987 #if PHP_MAJOR_VERSION >= 7
988 				option_num = Z_LVAL_P(data);
989 #else
990 				option_num = Z_LVAL_PP(data);
991 #endif
992 			}

FIX:

981 #if PHP_MAJOR_VERSION >= 7
982                         if (Z_TYPE_P(data) == IS_STRING) {
983 #else	
984 			if (Z_TYPE_PP(data) == IS_STRING) {
985 #endif
986 //------------- fix ---------------
987 #if PHP_MAJOR_VERSION >= 7
988 				option_str = Z_STRVAL_P(data);
989 #else
990 				option_str = Z_STRVAL_PP(data);
991 #endif
    //------------- end fix ---------------
992 			} else {
993 #if PHP_MAJOR_VERSION >= 7
994 				option_num = Z_LVAL_P(data);
995 #else
996 				option_num = Z_LVAL_PP(data);
997 #endif
998 			}
