What is a string? A string is a sequential sequence of characters, consisting of numbers, letters, and symbols. Each character in the string occupies only one byte. In PHP, there are three ways to define strings, namely single quotation marks ('), double quotation marks ("), and delimiters (<<<). Single and double quotes are often used to define a string, defined as follows: Single quote <?php$a= ' topic.alibabacloud.com ';? > Double quotes <?php$a= "topic.alibabacloud.com";? > The difference between single and double quotation marks is that the variables contained in the double quotes are automatically replaced with the actual values, and the variables contained in the single quotation marks are created as normal characters, so what do you mean, let's get down here. Example < for example single and double quotation marks where the string differs from one another; Phpheader ("Content-type:text/html;charset=utf-8"); &

2. Parsing PHP Data type strings (string)
Summary: A string of strings consists of a series of characters, each of which is equal to one byte. This means that PHP can only support a 256 character set and therefore does not support Unicode. See detailed string types. Note:string ...
3. Verify that Java is not a purely object-oriented language in detail
Introduction: Is java--really "object-oriented"? Let's go deep into the Java world and try to prove it. In my first few years of learning Java, I learned from the book that Java follows the object-oriented programming paradigm (oriented programming paradigm). In the Java World everything is objects, even strings (string) These are objects (in C, strings are character arrays), then I think Java is an object-oriented language. But later on, I was connected.

7. PHP String Operators
Summary: There are two strings (string) operators. The first one is the join operator (".") ), which returns the string after its left and right arguments are concatenated. The second is the Join assignment operator (". ="), which attaches the right argument to the left argument. For more information, see assignment operators.
