PHP regex for image name with numbers -

-

मेरे नाम के साथ चित्र हैं जैसे: 

  img-300x300.jpg img1-250x270 .jpg   
 ये नाम एक स्ट्रिंग चर में संग्रहीत किए जाएंगे। मेरी छवि Wordpress में है, इसलिए यह उदाहरण पर स्थित होगी  
 mywebsite.com/wp-content/uploads/2012/11/img-300x300.jpg  
 और मुझे बदलने की स्ट्रिंग की आवश्यकता  
 mywebsite .com / wp-content / uploads / 2012/11 / img.jpg  
 मुझे एक PHP नियमित अभिव्यक्ति की आवश्यकता है जो कि नाम के रूप में आईएमजी.जेपीजी और आईएमजी 1.जीपीजी लौटाएगा।  
 मैं यह कैसे करूँ?  
 धन्यवाद  
 इसके अतिरिक्त  
 क्षमा करें, मैंने इसे करने की कोशिश की थी लेकिन यह काम नहीं कर रहा है  
 < कोड> $ स्ट्रिंग = 'आईएमजी-300x300.jpg' $ पैटर्न = '[^ 0-9।] - [^ 0-9।]'; $ प्रतिस्थापन = ''; गूंज preg_replace ($ पैटर्न, $ प्रतिस्थापन, $ स्ट्रिंग);    
 
 
 आप यह ऐसा करने के लिए PHP देशी फ़ंक्शंस का उपयोग कर सकते हैं।  
  & lt;? Php फ़ंक्शन genLink ($ imagelink) {$ img1 = basename ($ कल्पना); $ img = substr ($ img1,0, strrpos ($ img1, '-'))। substr ($ img1, strpos ($ img1, '।')); $ संशोधित लिंक = उपस्ट्रैक्ट ($ कल्पना, 0, स्ट्रॉपो ($ कल्पना, '/'))। "/"। $ Img; $ संशोधित लिंक वापस करें; } गूंज genLink ('mywebsite.com/wp-content/uploads/2012/11/flower-img-color-300x300.jpg');   
   आउटपुट:    
  mywebsite.com/wp-content/uploads/2012/11 / फ्लॉवर-img-color.jpg

sql - Postgresql record to array -

-
I need to change back into an array to change lines from the array and filter the records. I am using info_schema._pg_expandarray in a SELECT query to get a line copy value in the array. Looking at the following array: "four" [] {i, i, o, t, b} _pg_expandarray leaves 5 rows with 1 row type record: records (I, 1) (i, 2) (o, 3) (t, 4) I have to filter this result set 't' to exclude record records. How can I do this? Should I convert back to the array? What is a way to filter the array directly? Thanks in advance. If your purpose is to create one set of the above rows, but remove the 't' in the line So, this is the trick: test => Information (i), 'o', 't', 'b' i. N --- --- --- i | 1 mother 2 o | 3b 5 (4 lines) As a side, unless you specifically want to return the index as a second column, then I unnest () information_schema._pg_expandarray () , which does not appear in the document and is probably...

c++ - Cmake produces file extensions in static library archives -

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
