Hello
I'm new and I want to port the PEAR HTML_Template_Sigma Class to an PHP
extension.
I startet with the old book 'Building custom PHP Extensions' found now
newer one.
At the moment i have some class functions in my extension as they are in
the PHP Class.
So i try doing some bench :(
Testing with php7.
i call the class constructor from the extension 1000 times and also the
same with the PHP class.
$x = new HTML_Template_Sigma("dir","dir_cache");
PHP Class without opcache
MEM: 2 mb, Time: 0.0366 sec
PHP Class with opcache
MEM: 2 mb, Time: 0.0269 sec
Class from the extension
MEM: 2 mb, Time: 0.0363 sec
so the PHP Class with opcache ist faster as my extension.
My goal was to write the class as an extension to get faster.
so in the __construct from the PHP class are callback functions this one
sets PHP or class methods as an class property in an array.
$this->setCallbackFunction('h', array(&$this, '_htmlspecialchars'));
$this->setCallbackFunction('e', array(&$this, '_htmlentities'));
$this->setCallbackFunction('u', 'urlencode');
$this->setCallbackFunction('r', 'rawurlencode');
$this->setCallbackFunction('j', array(&$this, '_jsEscape'));
when i set urlencode and rawurlencode in my extension like this it costs
0.01 sec
zval tplFunction;
ZVAL_STRING(&tplFunction,"u");
zval callback;
ZVAL_STRING(&callback,"urlencode");
zend_call_method_with_2_params ( obj,Template_Sigma, NULL,
"setcallbackfunction", NULL, &tplFunction, &callback);
bench without the urlencode and rawurlencode call in the extension
MEM: 2 mb, Time: 0.0262 end
so I'm on the wrong way ?
And if I'm on the write way how can i pass the object from a private
method of the PHP extension class to the setcallback function as it is
down in PHP with
$this->setCallbackFunction('h', array(&$this, '_htmlspecialchars'));
array(&$this, '_htmlentities')
The next question should I use call_user_function or write this function
in C.
for example
the private methode _jsEscape uses the PHP strtr and the second
parameter is an array so the internal php_strtr_array function is
called. Should I instead call the php_strtr function multiple times ?
Best Regards
Torsten
