PHP: variable not working inside of function? -

-

<पूर्व> $ पथ गूंज; // काम करने की फंक्शन बनावट सूची ($ पुनर्प्रवल) {echo $ path; // प्रिंट काम नहीं कर रहा है "& lt; form method = 'POST' क्रिया = '' enctype = 'multipart / form-data' & gt;"; ($ $ मूल्य के रूप में लौटाया गया है) {प्रिंट "& lt; इनपुट प्रकार = 'चेकबॉक्स' नाम = 'हटाए गए फाइल्स []' id = '$ value' value = '$ value' & gt; $ value & lt; br & gt;"; } प्रिंट "& lt; इनपुट वर्ग = 'submit' name = 'deleteBtn' प्रकार = 'जमा करें' मान = 'दिनांकई (एन) लॉस्चन' & gt;"; प्रिंट "& lt; / form & gt;"; }

मैं क्या कर रहा हूँ गलत? क्यों $ पथ सही createlist फ़ंक्शन के बाहर मुद्रित है, लेकिन यह फ़ंक्शन के अंदर पहुंच योग्य नहीं है?

क्योंकि यह फ़ंक्शन में परिभाषित नहीं है।

इसके बारे में कुछ तरीके हैं:

1) एलेक्स को बता कर कहें फ़ंक्शन यह एक वैश्विक चर है: 

  $ पथ गूंज; // काम कर रहे फ़ंक्शन बनावट सूची ($ रेटवाल) {वैश्विक $ पथ; $ पथ गूंज; // कार्य

2) इसे स्थिर के रूप में परिभाषित करें: 

  परिभाषित करें (पैट, "/ मेरा / परीक्षण / पथ "); // आप इसे एक फ़ाइल में भी डाल सकते हैं। गूंज पाथ; // काम करने की फंक्शन बनावट सूची ($ रेटवाल) {echo PATH; // कार्य

3) फ़ंक्शन में इसे पारित करें यदि यह उस फ़ंक्शन के लिए विशिष्ट है: 

  प्रतिध्वनि $ पथ; // काम कर रहे फ़ंक्शन createList ($ retval, $ path) {गूंज $ पथ; // कार्य

फ़ंक्शन वास्तव में आपके लिए कैसे काम करता है इसके आधार पर, उनमें से एक फिर से करेंगे।

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
