Hi,
You should understand that the current php_embed code isn't ready to be
runned within any type of context (C context or C++ object context).
It is just a ONE Shot execution.
Have a look at :
http://cvs.php.net/viewcvs.cgi/php-src/sapi/embed/php_embed.c?view=markup&rev=1.1.2.5.2.1
You can see that the request is destroyed at the shutdown time (should be
your class destructor).
void php_embed_shutdown(TSRMLS_D)
{
php_request_shutdown((void *) 0);
[..]
}
That why i have develop a different way to allow you (for example) to keep a
PHP context within an Object.
http://www.badcode.be/~descript/PHP/php_embed/
To install it you just have to replace php_embed.c & php_embed.h from your
sapi/embed/ .
Now i give to you an example :
class MyObject {
public: MyObject() {
this->ctx = php_embed_ctx_init();
php_embed_ctx_set_var(
this->ctx,
PHP_EMBED_VKEY("MyObject"),
this
);
};
public: ~MyObject() {
php_embed_ctx_fini(this->ctx);
};
public: execute(char *code) {
php_embed_ctx_execute(this->ctx, code);
};
private: php_embed_ctx *ctx;
}
php_embed_ret my_stdout(php_embed_ctx *ctx, const char *str, uint str_l) {
MyObject **obj;
PHP_EMBED_LOAD_VKEY_FROM(ctx, obj, "MyObject");
// your object is here
// (*obj)->something
return(PHP_EMBED_HOOK);
}
There is other useful possiblity but actualy you'll need to look my comments
at http://www.badcode.be/~descript/PHP/php_embed/php_embed.h
I don't have many time to make more documentation. And you must to know that
this modification isn't official so i don't have motivation to continue.
/* API */
php_embed_ctx *php_embed_ctx_init();
int php_embed_ctx_fini(php_embed_ctx *);
int php_embed_ctx_execute(php_embed_ctx *, char *);
int php_embed_ctx_add_funcs(php_embed_ctx *, zend_function_entry *);
int php_embed_ctx_set_var(php_embed_ctx *, char *, uint, void *);
int php_embed_ctx_unset_var(php_embed_ctx *, char *, uint);
void *php_embed_ctx_find_var(php_embed_ctx *, char *, uint);
/* standard output */
int php_embed_ctx_set_stdout(
php_embed_ctx *,

int php_embed_ctx_unset_stdout(php_embed_ctx *);
/* flush */
int php_embed_ctx_set_flush(
php_embed_ctx *,

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
