If you want a new object with two keys, Object1 and Object2, you can do: JSONObject Obj1 = (JSONObject) jso1.get(“Object1”); JSONObject Obj2 = (JSONObject) jso2.get(“Object2”); JSONObject combined = new JSONObject(); combined.put(“Object1”, Obj1); combined.put(“Object2”, Obj2); If you want to merge them, so e.g. a top level object has 5 keys (Stringkey1, ArrayKey, StringKey2, StringKey3, StringKey4), I … Read more
The push() adds elements to the end of an array and returns the new length of the array. Thus your return here is invalid. The concat() method is used to merge arrays. Concat does not change the existing arrays, but instead returns a new array. Better to filter, if you want a NEW array like … Read more
You can use tr: { echo “The quick”; echo “brown fox”; } | tr “\n” ” ” OR using sed: { echo “The quick”; echo “brown fox”; } | sed ‘:a;N;s/\n/ /;ba’ OUTPUT: The quick brown fox
Whatever works best for you works… But if you want to go for speed use this: echo ‘Welcome ‘, $name, ‘!’; The single quotes tell PHP that no interpretation is needed, and the comma tells PHP to just echo the string, no concatenation needed.
Your code concatenates three strings, then converts the result to a number. You need to convert each variable to a number by calling parseFloat() around each one. total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);
Use arrays: let lineComponent = <Line key={line.client_id} line={line}/>; if (line.created_at) { return [ <div key=”date” className=”date-line”><strong>{line.created_at}</strong></div>, lineComponent, ]; } else { return chat_line; } Or use fragments: import createFragment from “react-addons-create-fragment”; let lineComponent = <Line key={line.client_id} line={line}/>; if (line.created_at) { return createFragment({ date: <div className=”date-line”><strong>{line.created_at}</strong></div>, lineComponent: lineComponent, }); } else { return chat_line; } In … Read more
No, there is no type of stringbuilder class in PHP, since strings are mutable. That being said, there are different ways of building a string, depending on what you’re doing. echo, for example, will accept comma-separated tokens for output. // This… echo ‘one’, ‘two’; // Is the same as this echo ‘one’; echo ‘two’; What … Read more
From Oracle 11gR2, the LISTAGG clause should do the trick: SELECT question_id, LISTAGG(element_id, ‘,’) WITHIN GROUP (ORDER BY element_id) FROM YOUR_TABLE GROUP BY question_id; Beware if the resulting string is too big (more than 4000 chars for a VARCHAR2, for instance): from version 12cR2, we can use ON OVERFLOW TRUNCATE/ERROR to deal with this issue.
Both will have a key of 0, and that method of combining the arrays will collapse duplicates. Try using array_merge() instead. $arr1 = array(‘foo’); // Same as array(0 => ‘foo’) $arr2 = array(‘bar’); // Same as array(0 => ‘bar’) // Will contain array(‘foo’, ‘bar’); $combined = array_merge($arr1, $arr2); If the elements in your array used … Read more
From the docs: Multiple adjacent string literals (delimited by whitespace), possibly using different quoting conventions, are allowed, and their meaning is the same as their concatenation. Thus, “hello” ‘world’ is equivalent to “helloworld”. Statement 3 doesn’t work because: The ‘+’ operator must be used to concatenate string expressions at run time. Notice that the title … Read more
