PHP function confusion -

-

मेरे पास निम्न परिदृश्य (सरलीकृत) है: 

  फ़ंक्शन परिवर्तन फर्म ($ फलों) { changeAgain ($ फल); } फ़ंक्शन परिवर्तनआगेन ($ फलों) {$ फल = "ऑरेंज"; } मुख्य: $ फल = "ऐप्पल"; changeFruit ($ फल); $ फोकस गूंज / "एप्पल" के रूप में दिखाई देगा, मैं इसे "ऑरेंज" के रूप में कैसे दिखा सकता हूं ??

संपादित करें: जोड़ने के लिए हटाएं SCENARIO वापस स्टेटमेंट्स का उपयोग नहीं कर सकता - केवल & amp; $ चर

धन्यवाद! मैट म्यूएलर

जब आप कुछ पास करते हैं जो PHP में फ़ंक्शन के लिए ऑब्जेक्ट नहीं है, तो php एक प्रतिलिपि बनाता है फ़ंक्शन के भीतर इसका उपयोग करने के लिए।

इसे किसी प्रति का उपयोग नहीं करने के लिए, आपको एक PHP संदर्भित करने की आवश्यकता है।

यह & amp; ऑपरेटर

<पूर्व> फ़ंक्शन परिवर्तन फर्म (और $ फलों) {changeAgain ($ fruit); } फ़ंक्शन परिवर्तनआगेन (और $ फलों) {$ fruit = "ऑरेंज"; } $ फल = "ऐप्पल"; changeFruit ($ फल); प्रतिफल $ फलों;

फ़ंक्शन के रिटर्न वैल्यू का उपयोग करने के लिए यह अधिक समझदार और बेहतर अभ्यास होगा (क्योंकि इससे चीजों को पढ़ने में आसान होता है) 

  फ़ंक्शन परिवर्तन फर्म ( $ फलों) {वापसी परिवर्तनअगेन ($ फलों); } फ़ंक्शन परिवर्तनअगैन ($ फलों) {/ / $ $ फल = "ऑरेंज" यहां फल के साथ और अधिक रोचक कार्य करें; वापसी $ फलों; } $ फल = "ऐप्पल"; $ फल = परिवर्तनफुट ($ फलों); प्रतिफल $ फल

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
