objective c - string has prefix PHP -


संभव डुप्लिकेट:

कैसे एक बयान करता है कि अगर $ mystring का उपसर्ग "http: //" है, तो {कुछ करो}।

मैंने उद्देश्य-सी में ऐसा किया है: 

  यदि ([mynsstring हैप्रफ़िक्स: @ "http: //"]) {// कुछ करें ...}   
 मुझे नहीं पता कि कैसे PHP में ऐसा करें अग्रिम में आपकी सहायता के लिए धन्यवाद।   
 
 
 सरलतम  
 < Code> if (substr ($ mystring, 0, 7) === 'http: //') {// कुछ करना}   
 अक्षरों की सही संख्या लेने के लिए निश्चित रूप से याद रखें ।

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.

Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
