I found the solution myself :-))!! Basically using the active_symbol_table
instead of
the symbol_table and adding +1 to the sizeof(), I solved the problem :-))!!!
zval **data = NULL;
HashTable *arrayHash = NULL;
void *prev_interp = NULL;
prev_interp = tsrm_set_interpreter_context( self->interp );
{
TSRMLS_FETCH();
if ( zend_hash_find( EG(active_symbol_table), "myVar", sizeof( "myVar" )+1,
(void **)&data) == FAILURE )
{
fprintf( stderr, "The infoString array myVar not found in $GLOBALS" );
goto out;
}
if ( data == NULL )
{
fprintf( stderr, "myVar doesn't contains any data" );
goto out;
}
}
out:
tsrm_set_interpreter_context( prev_interp );
Now my problem is how to find declared functions in a context. Which hash table
I have to use?
