您要查找的是不是：
- Notice that there is no concatenation operator. 请注意没有串联运算符。
- PHP uses the period (.) as the concatenation operator. PHP使用句点号作为它的操作符.
- If either one is Null, the result of the whole concatenation operation is Null. 如果二者之一为空的， 整体运算结果是空的。
- The string concatenation operator is collation insensitive, the two string operands and the result are assigned the collation label of the operand with the highest collation precedence. 字符串串联运算符不区分排序规则,两个字符串操作数和结果被赋以具有最高排序规则优先顺序的操作数的排序规则标签。
- In that case, the individual concatenation operations might even be combined into a single operation by the compiler. 这种情况下,编译器甚至会将各个串联操作组合到一个操作中。
- Both carry out the basic concatenation operation, as the following example shows. 这两种串联运算符都执行基本的串联运算,如下面的示例所示。
- When ON is specified, the result of a concatenation operation is NULL when either operand is NULL. 当指定为ON时,如果串联操作的两个操作数中任意一个为NULL,则结果也为NULL。
- The performance of a concatenation operation for a String or StringBuilder object depends on how often a memory allocation occurs. String或StringBuilder对象的串联操作的性能取决于内存分配的发生频率。
- The arithmetic and concatenation operators have the order of precedence described below, and all have higher precedence than the comparison, logical, and bitwise operators. 算术运算符和串联运算符具有下述优先级顺序,它们的优先级均高于比较运算符、逻辑运算符和位运算符。
- The concatenation operator ignores null operands. For example, the expression 连接字符操作忽略空的操作数
- There are two concatenation operators, 有两种串联运算符
- Differences Between the Two Concatenation Operators 两种串联运算符之间的区别
- Operator to force string concatenation. 运算符来强制字符串连接。
- In this lesson, you learned how to declare and assign strings, and how to join strings with the concatenation operator 在本课中,您学习了如何声明字符串并给字符串赋值,以及如何使用串连运算符
- Loosely, a mathematical or logic operator. 不严格地说，一种数学或逻辑运算符。
- That store operator ripped me off. 那个商店的营业员把我骗了。
- The operator told the caller that the line is busy. 接线生告诉打电话的人对方电话占线。
- Ring the operator and ask for Freefone 8921. 接通接线生，然後要免费通话8921号。
- The intricate machine requires a skilled operator. 这种复杂精细的机器须由技能熟练的人操作。
- Using the defined reasonable task assignment path and its concatenate operation, the solution of And/Or tree of WAR was studied. 利用定义的合理指派路径及其串联操作，分析了工作流授权合理性问题与／或树节点的可解性。
