Beginning with PHP object-oriented programming feels a bit awkward.

Initial use of PHP object-oriented programming feel a bit awkward ...
Because always do the front end with JS
This is generally used
function xx () {
This.init.apply (this,arguments);
}

Xx.prototype = {
Options: {
A few default properties
},
Init:function (options) {
$.extend (this,this.options,options);
It's easy to write a extend without jquery.
//.........
}
}

New XX (AA)//AA is an object that passes some parameters
$.extend (this,this.options,options); This is the example of a new argument with the default parameter, which is easy to implement.

When I wrote PHP today (my colleague told me to have one assignment)
The following code (merge js css things)

Class Mergecompress
{
var $merge _arr;
var $commpress _arr;
var $type;
var $file _dir; Compress the merged directory
var $file _name; Compress the merged file name
var $path _jar; Yui Jar Path
var $is _del = true; Whether the compressed fragmented files are deleted
var $errs = array ();
Public function __construct ($commpress _arr=array (), $merge _arr=array (), $type = "js", $file _dir= "", $file _name= "", $ Path_jar= "") {
$this->type = $type;
$this->commpress_arr = $commpress _arr;
$this->merge_arr = $merge _arr;
$this->file_dir = $file _dir;
$this->file_name = $file _name;
$this->path_jar = $path _jar;
}
Public function exec () {
$new _compress_arr = $this->compress ();

$this->merge_arr = Array_merge ($this->merge_arr, $new _compress_arr);

$this->merge ();

if ($this->is_del) {
foreach ($new _compress_arr as $i = + $url) {
Unlink ($url);
}
}
}
Public Function compress () {
$new _compress_arr = Array ();
$temp = "Java-jar {Jar_path}--type {type}--charset utf-8 {source} > {compressor_source}";
$temp = Str_replace ("{Jar_path}", $this->path_jar, $temp);
$temp = Str_replace ("{type}", $this->type, $temp);
$type = $this->type;
$file _dir = $this->file_dir;
foreach ($this->commpress_arr as $i = + $val) {
if (!file_exists ($val)) {
Array_push ($this->errs, $val. " Does not exist!!!! ");
Continue
}
$cmd = Str_replace ("{source}", $val, $temp);
$new _name = basename ($val);
$new _name = substr ($new _name,0,strrpos ($new _name, ".")). ". Min. ". $type;
$file _new_name = $file _dir. " /". $new _name;
$cmd = Str_replace ("{Compressor_source}", $file _new_name, $cmd);
$arr = Array ();
EXEC ($cmd, $arr, $is);
if ($is! = 0) {
Array_push ($errs, $val. " Compress fail!!!! ");
}
Array_push ($new _compress_arr, $file _new_name);
}
return $new _compress_arr;
}
Public Function merge () {
$content = "";
$file _name = $this->file_dir. " /". $this->file_name;

foreach ($this->merge_arr as $i = + $url) {
if (!file_exists ($url)) {
Array_push ($this->errs, $url. " Does not exist!!!! ");
