关于ereg的说明,有句话不理解解决方法
关于ereg的说明,有句话不理解
php帮助文档这么说的:
说明
int ereg ( string $pattern , string $string [, array &$regs ] )
...
...
“如果在 string 中找到 pattern 模式的匹配则返回 所匹配字符串的长度,如果没有找到匹配或出错则返回 FALSE。如果没有传递入可选参数 regs 或者所匹配的字符串长度为 0,则本函数返回 1。 ”
------解决方案--------------------
怎么不可能
- PHP code
$date='2012-10-16';$r=ereg ("([0-9]{4})-([0-9]{1,2})-([0-9]{1,2})", $date);var_dump($r); // int(1)<br><font color="#e78608">------解决方案--------------------</font><br>别ereg了,这函数要被抛弃了的<br><font color="#e78608">------解决方案--------------------</font><br>这个函数在5.3里面就已经不能使用了,会报出错误,被遗弃的函数,已经使用preg_match来代替了.<br>两者使用的方法是一样,第一个参数是模式,也就是正则的模式,第二个参数是要匹配的字符串.<div class="clear"> </div>

Convert basic data types to strings using Java's String.valueOf() function In Java development, when we need to convert basic data types to strings, a common method is to use the valueOf() function of the String class. This function can accept parameters of basic data types and return the corresponding string representation. In this article, we will explore how to use the String.valueOf() function for basic data type conversions and provide some code examples to

Method of converting char array to string: It can be achieved by assignment. Use {char a[]=" abc d\0efg ";string s=a;} syntax to let the char array directly assign a value to string, and execute the code to complete the conversion.

Replace characters (strings) in a string using Java's String.replace() function In Java, strings are immutable objects, which means that once a string object is created, its value cannot be modified. However, you may encounter situations where you need to replace certain characters or strings in a string. At this time, we can use the replace() method in Java's String class to implement string replacement. The replace() method of String class has two types:

Hello everyone, today I will share with you the basic knowledge of Java: String. Needless to say the importance of the String class, it can be said to be the most used class in our back-end development, so it is necessary to talk about it.

Use Java's String.length() function to get the length of a string. In Java programming, string is a very common data type. We often need to get the length of a string, that is, the number of characters in the string. In Java, we can use the length() function of the String class to get the length of a string. Here is a simple example code: publicclassStringLengthExample{publ

In Golang programming, byte, rune and string types are very basic and common data types. They play an important role in processing data operations such as strings and file streams. When performing these data operations, we usually need to convert them to each other, which requires mastering some conversion skills. This article will introduce the byte, rune and string type conversion techniques of Golang functions, aiming to help readers better understand these data types and be able to apply them skillfully in programming practice.

1. Understanding String1. String in JDK First, let’s take a look at the source code of the String class in the JDK. It implements many interfaces. You can see that the String class is modified by final. This means that the String class cannot be inherited and there is no subclass of String. class, so that all people using JDK use the same String class. If String is allowed to be inherited, everyone can extend String. Everyone uses different versions of String, and two different people Using the same method shows different results, which makes it impossible to develop the code. Inheritance and method overriding not only bring flexibility, but also cause many subclasses to behave differently.

The split method in String uses the split() method of String to split the String according to the incoming characters or strings and return the split array. 1. General usage When using general characters, such as @ or, as separators: Stringaddress="Shanghai@Shanghai City@Minhang District@Wuzhong Road";String[]splitAddr=address.split("@");System .out.println(splitAddr[0]+splitAddr[1]+splitAddr[2]+splitAddr[3
