Hi All
I am back again :-)

The c++ guys are still having some problems and they have given me some
more info..
The app is init'd using the following
__declspec(dllexport) void InitPHPEngine(const CString& sStartupDir)
{
static bool bInitialised = false;
if (!bInitialised)
{
int argc = 1;
char *argv[2] = {"Actinic", NULL};
php_embed_module.ub_write = ub_write; // output is redirected to our
callback function
php_embed_module.log_message = log_message;
php_embed_module.sapi_error = sapi_error;
php_embed_module.php_ini_path_override = ".\\";
php_embed_init(argc, argv PTSRMLS_CC); // init the engine
CString sInit = PHP_INIT_SCRIPT;
if (!sStartupDir.IsEmpty()) // if startup dir is defined
{
CString sPath;
sPath.Format("chdir(\"%s\");",
CTextUtils::MakeStringSafeForQuotedPerlFragment(sStartupDir));
sInit += sPath;
}
zend_eval_string(sInit.GetBuffer(), NULL, "main" TSRMLS_CC);
bInitialised = true;
}
}
They then have a method
BOOL PHPEvalString(const CString& sCode, zval *pzvalResult, bool
bExpression)
{
CString sPreparedCode;
if (bExpression) // we should apply a trick for expressions
{
sPreparedCode.Format(_T("%s ? true : false"), sCode);
}
else
{
sPreparedCode = sCode;
gsPhpOutput.Empty();
gsPhpOutput.GetBuffer(sCode.GetLength()); // preallocate the string -
hopefully the result has similar length as the original script, so
probably that's a good guess
gsPhpOutput.ReleaseBuffer(); // doesn't release the extra bytes
}
char* pcScript = sPreparedCode.GetBuffer(sPreparedCode.GetLength());
zend_first_try
{
PG(during_request_startup) = 0;
int nResult;
if (bExpression)
{
nResult = zend_eval_string(pcScript, pzvalResult, "main" TSRMLS_CC);
}
else
{
nResult = zend_eval_string(pcScript, NULL, "main" TSRMLS_CC);
}
if (nResult == FAILURE)
{
return FALSE;
}
}
zend_catch
{
return FALSE;
}
zend_end_try();
return TRUE;
}
Therefore they want to shut down the request after the line
nResult = zend_eval_string(pcScript, NULL, "main" TSRMLS_CC);
and restart it for the next call
But doing
nResult = zend_eval_string(pcScript, NULL, "main" TSRMLS_CC);
TSRMLS_FETCH();
php_request_shutdown(NULL);
php_request_startup(TSRMLS_C);
Causes an immediate crash when it reaches php_request_startup(TSRMLS_C); :(
Also because init, eval and shutdown are in separate functions tsrm_ls
is defined as static in the app.
The also sent me the following backtrace if its of any use..
php4ts.dll!00d45b61()
php4ts.dll!00d45622()
user32.dll!77d6ebe2()
php4ts.dll!00d43e16()
> ActPHPRunner.dll!PHPEvalString(const
ATL::CStringT<char,StrTraitMFC_DLL<char,ATL::ChTraitsCRT<char> > > &
sCode={...}, _zval_struct * pzvalResult=0x0012e558, bool
bExpression=false) Line 372 + 0x7c C++
Any advice is greatly appreciated.
Regards
Mark
