php - How to escape only certain characters -


php फ़ंक्शन preg_quote इन अक्षरों से बचता है । \ + *? [^] $ () {} =! & LT; & Gt; | : -

क्या आप कृपया सुझाव दे सकते हैं कि इन अक्षरों से बचने के लिए मैं क्या उपयोग कर सकता हूं: + - & amp; amp; || ! () "" होल्डिंग "के रूप में अनुरोध किया गया है:

संपादित : < P> मैं एक सोलर खोज को लागू कर रहा हूं और यह कहता है:

सोलर निम्नलिखित प्रश्नों को विशेष अर्थ देता है, जब वे एक क्वेरी में दिखाई देते हैं:
+ - & amp; ; & Amp; ||! () {} [] ^ "~ *? : /

सोलर इन अक्षरों में से किसी को शाब्दिक रूप से व्याख्या करने के लिए, बल्कि एक विशेष वर्ण के रूप में, एक बैकस्लैश वर्ण के साथ चरित्र से पहले।

यह आपकी मदद कर सकता है: 

  & lt;? Php $ subject = "+ - - & amp; ||! {} [] ^ \ "~ *? : / "; $ Result = preg_replace ('% ([+ \ - & amp; |! () {} [\] ^" ~ *?: /] +)%', '\\\\ $ 1', $ विषय ); प्रतिफल $ परिणाम; ? & Gt;

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
