dl() is deprecated an deleted on some SAPIs

You shouldn't use dl() in your wiringpi.php script because it is deprecated. On my system, for instance, the script is unable to load the library because dl() is disabled.

I noticed this recently. However wiringpi.php is generated by SWIG and can't be changed directly. However dl() is only a fallback for if the library is not already loaded via php.ini, so it shouldn't really be encountered.

On this note, using PHP 5.6.4, doing include("wiringpi.php"); fails because this needs to be commented out:

/* // Try to load our extension if it's not already loaded. if (!extension_loaded('wiringpi')) { if (strtolower(substr(PHP_OS, 0, 3)) === 'win') { if (!dl('php_wiringpi.dll')) return; } else { // PHP_SHLIB_SUFFIX gives 'dylib' on MacOS X but modules are 'so'. if (PHP_SHLIB_SUFFIX === 'dylib') { if (!dl('wiringpi.so')) return; } else { if (!dl('wiringpi.'.PHP_SHLIB_SUFFIX)) return; } } } */

Hi, which would is the solution to it ? Sorry i am a newie on this. Thanks

I have no idea, I can't get the extension to work on PHP 5.5.33 or 5.6.4 still.

You'd need to place the wiringpi.so into an appropriate PHP extensions dir and load it in php.ini, I got it up and running recently but I'm not a regular PHP user so I had to puzzle out what I was doing. I'll try to replicate and produce a guide.

I did that, of course. Loaded the extension in php.ini as well as instructed. Doesn't work in PHP 5.5.33 or 5.6.4. What version of PHP are you using?

I included the generated wiringpi.so as an extension in php.ini, but apache's error log gives:
H00169: caught SIGTERM, shutting down
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20131226/wiringpi.so' - /usr/lib
/php5/20131226/wiringpi.so: undefined symbol: serialPutchar in Unknown on line 0

If I check the source code, there should be a serialPutchar function. Am I missing something?
