Disable Garbage Collection?

I have a WP site which creates 500's errors for about 2% of Apache requests (mostly bots and crawlers). I'm not able to stack trace most of those requests with 500's neither to PHP or MySQL errors.

Is it good idea to disable a garbage collection (gc_disable()) for the whole WP site to prevent any memory leak caused by a theme or plugins?

Wordpress SMS API integration without plugin

I am struggling with SMS sending in WordPress without plugin, I have a, API, but that API is not working. Example:

function mysite_woocommerce_order_status_processing( $order_id ) {

$mobile="123456";

$url="****/api.php?username=******&password=1234&source=UPDATE&dmobile=".$mobile."&message='.$msg.' ";

$response = wp_remote_get( $url ); //print_r($response);

} add_action( 'woocommerce_order_status_processing','mysite_woocommerce_order_status_processing' );

I am struggling with above hook, I can send Email through that hook, but not SMS. It would be great if any WordPress developer help me out !

Is there a way to optimize function that is used for returning data in an ajax-call?

I've started creating some plugins (not offically deployed yet) (feel free to use it you want to), and now my goal is to include a custom post type and taxonomy and being able to use Advanced Custom Fields if wanted. The purpose of the plugin is to create a list based on custom taxonomy / custom post types and being able to put that anywhere on any page (with a shortcode) and when selecting anything from that list fetch content from the selected custom post type) and put it into another div without page reload.

This is my code (forgive the swedish part, but it's not neccessary I think for the actual question):

<?php
/*
Plugin Name: ListAjax

    }

}        
$listajax = new listajax();
$listajax->init(); //Execute AFTER user defined settings are set
}

The result_div() - function is returning data to the javascript:

jQuery(function ($) {
    //Ajax-retrieve value from selected custom post type (that is shown in list)          
    $('.ajaxlistform').on('change', '.ajaxlist', function(e) {   
       var t = $(this);
       var post_id = $(this).val();  //Value from selectlist

        var listajaxvalues = $.ajax({            
            type: 'POST',
            data:{
                action: 'set_contactinfo',    
                post_id: post_id
            },
            url: '/wp-admin/admin-ajax.php',
            dataType: 'html'
        });

        //Put data into resultdata div that is set inte data-resultdiv attribute
        listajaxvalues.done(function(data) {
                var result_data = t.data('resultdiv');
                $(result_data).html(data);
                return;
        });                        

        listajaxvalues.fail(function(ts) {           
            alert(ts.responseText);
       });


    });

});

Is there a way to optimize (in terms of speed) the result_div() - function? It takes about a second to retrieve information. It does not sound like a lot of time, but when selecting from the selectlist, it seems like forever ;-)

How to get popular post tags

I need to get post popular tags. Here what I found from http://ift.tt/1MVBmsj

$tag = wp_tag_cloud( 'smallest=8&largest=22&number=2&orderby=count&format=array' );

Here is an example from Wordpress site:

Cloud displayed under Popular Tags title

<?php if ( function_exists( 'wp_tag_cloud' ) ) : ?>    
<h2>Popular Tags</h2>
<ul>
<li><?php wp_tag_cloud( 'smallest=8&largest=22' ); ?></li>
</ul>    
<?php endif; ?>

I did not understand this parameters meaning smallest=8&largest=22 and does this example what I need?
