php - Fatal error: Cannot access parent:: when current class scope has no parent in -

- 

  सार्वजनिक फ़ंक्शन __construct () {मूल :: __ निर्माण (); $ इस- & gt; load- & gt; config ( "मास्टर"); $ इस- & gt; उफ़ (); $ इस- & gt; डेटाबेस (); $ इस- & gt; load- & gt; config ( "लैंग"); $ इस- & gt; load- & gt; मॉडल ( "कार्यों"); }

कोड में क्या गलत है? मुझे पता नहीं क्या गलत है! क्या कोई मेरी सहायता कर सकता है?

मेरे अंग्रेजी के लिए क्षमा करें, मैं जर्मनी से आया हूँ!

< P> मूल :: एक विधि के मूल वर्ग कार्यान्वयन तक पहुंचने के लिए है आपकी कक्षा के पास कोई अभिभावक नहीं है, क्योंकि यह विस्तार नहीं करता है कोई भी वर्ग इसलिए त्रुटि। 

  वर्ग फ़ू {सार्वजनिक फ़ंक्शन बार () {गूंज 'बार'; }} वर्ग बाज़ फू {सार्वजनिक फ़ंक्शन बार ()) को बढ़ाता है (माता पिता :: बार (); गूंज 'बज़'; }}

यहां मूल समझ में आता है, क्योंकि एक अभिभावक वर्ग है। 

  वर्ग फ़ू {सार्वजनिक फ़ंक्शन बार () {मूल :: बार (); }}

यहां मूल कोई मतलब नहीं है, क्योंकि कोई माता पिता नहीं है, इसलिए त्रुटि चूंकि यह कोई मतलब नहीं है और कोई उद्देश्य नहीं है, इसलिए इसे हटा दें।

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
