【PHP】HTML Purifier 可過濾HTML限定只能用那些HTML
碰到只能用某些HTML,自己過濾超麻煩,
後來找到好用的套件 :HTML Purifier
裡面還有很多功能,也可阻擋XSS攻擊

【Jquery UI】拖移(sortable)抓到值
$(".cat1 .type-sort").sortable({update: function (e, ui){
$current_id = ui.item.attr('id');
$change_id = ui.item.prev().attr('id');
console.log(ui.item.attr('id')+'/'+ui.item.prev().attr('id'));
console.log($("#"+$current_id).html());
}});
$current_id = ui.item.attr('id');
$change_id = ui.item.prev().attr('id');
console.log(ui.item.attr('id')+'/'+ui.item.prev().attr('id'));
console.log($("#"+$current_id).html());
}});
【Jquery】動態產生也可綁定事件
利用Jquery產生出來的物件 (append、prepend),
在之前設定的$('.item').click()會失效,
要改成 $('body').on('click','.item',funciton (){});

【PHP】JSON 相關
1.編碼 JSON 時保留 key 值
$post_data = json_encode(array('aaa'), JSON_FORCE_OBJECT);
// 輸出 {"0":"aaa"}
2.解碼時用陣列
$array = json_decode($json, true);
echo $array['foo'] . PHP_EOL; //"bar"
echo $array['number'] . PHP_EOL; //42
3.陣列轉換成物件 {}
$obj = (object) array('1' => 'foo');
$a = new stdclass; $a->id = 11;
4.sublime prettify 的快捷鍵是 Ctrl + Alt + J (要先安裝)
$post_data = json_encode(array('aaa'), JSON_FORCE_OBJECT);
// 輸出 {"0":"aaa"}
2.解碼時用陣列
$array = json_decode($json, true);
echo $array['foo'] . PHP_EOL; //"bar"
echo $array['number'] . PHP_EOL; //42

$obj = (object) array('1' => 'foo');
$a = new stdclass; $a->id = 11;

【PHP】型態轉成object
有時要把型態轉成object可用
方法一: $obj = (object) array('1' => 'foo');
方法二:$a = new stdclass; $a->abc = 'abc';
目前有用到的時機
1.轉json時,為了符合別人定的API的JSON規則,需要轉成object
2.建立一個空的類只是為了傳遞或儲存參數時

【PHP】XML to array
/** * xml2array() will convert the given XML text to an array in the XML structure. * Link: http://www.bin-co.com/php/scripts/xml2array/ * Arguments : $contents - The XML text * $get_attributes - 1 or 0.

This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. * Return: The parsed XML in an array form. Use print_r() to see the resulting array structure. * Examples: $array = xml2array(file_get_contents('feed.xml')); * $array = xml2array(file_get_contents('feed.xml', 1, 'attribute')); */ function xml2array($contents, $get_attributes=1, $priority = 'tag') { if(!$contents) return array(); if(!function_exists('xml_parser_create')) { //print "'xml_parser_create()' function not found!"; return array(); } //Get the XML parser of PHP - PHP must have this module for the parser to work $parser = xml_parser_create(''); xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8"); # http://minutillo.com/steve/weblog/2004/6/17/php-xml-and-character-encodings-a-tale-of-sadness-rage-and-data-loss xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0); xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1); xml_parse_into_struct($parser, trim($contents), $xml_values); xml_parser_free($parser); if(!$xml_values) return;//Hmm... //Initializations $xml_array = array(); $parents = array(); $opened_tags = array(); $arr = array(); $current = &$xml_array; //Refference //Go through the tags. $repeated_tag_index = array();//Multiple tags with same name will be turned into an array foreach($xml_values as $data) { unset($attributes,$value);//Remove existing values, or there will be trouble //This command will extract these variables into the foreach scope // tag(string), type(string), level(int), attributes(array). extract($data);//We could use the array by itself, but this cooler. $result = array(); $attributes_data = array(); if(isset($value)) { if($priority == 'tag') $result = $value; else $result['value'] = $value; //Put the value in a assoc array if we are in the 'Attribute' mode } //Set the attributes too. if(isset($attributes) and $get_attributes) { foreach($attributes as $attr => $val) { if($priority == 'tag') $attributes_data[$attr] = $val; else $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr' } } //See tag status and do the needed. if($type == "open") {//The starting of the tag '' $parent[$level-1] = &$current; if(!is_array($current) or (!in_array($tag, array_keys($current)))) { //Insert New tag $current[$tag] = $result; if($attributes_data) $current[$tag.
