linux - Why I'm getting "sh" calling "echo $0" inside bash inside php exec? -


मेरे पास ऐसा कोड है: 

  सार्वजनिक फ़ंक्शन शेल ($ कोड) {$ code = Preg_replace ('/ "/', '\\' ', $ कोड); Exec ('bash -c' '$ code।' '', $ परिणाम); वापसी का परिणाम; }

और जब मैं shell ("echo $ 0") कॉल करता हूं; मैं bash के बजाय sh हो रहा हूं, क्यों?

मूल शेल डबलक्वॉट्स के भीतर चर का विस्तार कर रहा है। चर विस्तार को रोकने के लिए, एकल उद्धरणों का उपयोग करें: 

  exec ("bash -c '" $ code। "" ", $ Result);

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file. To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
