php - Regular expression to find all A tags which do not contain tag IMG inside it? -


मेरे पास एक HTML कोड है: 

  & lt; a href = "/ in-bai -viet - Choang-n20120711033726647.chn "लक्ष्य =" _ रिक्त "& gt; में & lt; आईएमजी src =" / छवियाँ / प्रिंटर पेज "alt =" बीएआई viết n "y में" / & gt; & Lt; / a & gt; & Lt; एक लक्ष्य = "_ रिक्त" rel = "nofollow" href = "http://ttvn.vn/" & gt; थियेंम लाम - टीटीवीएन & lt; / a & gt; & Lt; a href = "/ tinh-yeu-hon-nhan / 20120709102954599 / चे-लैंग- .chn" title = "'abc'" & gt; एबीसीडी & lt; / a & gt;   
 मुझे उस सभी टैग को हटाने की जरूरत है जिसमें आईगग टैग शामिल नहीं है। मैं इस नियमित अभिव्यक्ति का उपयोग कर रहा हूं:  
  preg_replace ('/ & lt; a (। *) [^ Img] (। *) & Lt; \ / a & gt; / सी', '', $ स्ट्रिंग);   
 मैंने भी  ^ (?!। + & Lt; img। +) & Lt; a href = \ "? \ '?। + \"? \'? & Gt; । & Lt; / a & gt; $  लेकिन असफल।  
 धन्यवाद   
 
 
 इसका प्रयोग करें:  
  (& lt; a [^ & lt;] * & gt;। & Lt; img [^ & gt;] * & gt; [^ & lt;] * & lt ; / A & gt;)   
 और रिक्त स्ट्रिंग के साथ प्रतिस्थापित करें। ।

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
