PHP将单词转换为数字,如单词zero、three、five、six、eight、one转换为数字035681。我可以通过foreach和switch循环来实现。
下面我们就结合具体的代码示例,给大家介绍PHP将单词转换为数字的实现方法。
代码示例如下:
<?php function word_digit($word) { $warr = explode(';',$word); $result = ''; foreach($warr as $value){ switch(trim($value)){ case 'zero': $result .= '0'; break; case 'one': $result .= '1'; break; case 'two': $result .= '2'; break; case 'three': $result .= '3'; break; case 'four': $result .= '4'; break; case 'five': $result .= '5'; break; case 'six': $result .= '6'; break; case 'seven': $result .= '7'; break; case 'eight': $result .= '8'; break; case 'nine': $result .= '9'; break; } } return $result; } echo word_digit("zero;three;five;six;eight;one")."<br>"; echo word_digit("seven;zero;one")."<br>";
输出结果如下:
相关函数介绍:
explode函数表示使用一个字符串分割另一个字符串。
说明 :
array explode ( string $delimiter , string $string [, int $limit ] )
此函数返回由字符串组成的数组,每个元素都是 string 的一个子串,它们被字符串 delimiter 作为边界点分割出来。
trim函数表示去除字符串首尾处的空白字符(或者其他字符)。
说明 :
string trim ( string $str [, string $character_mask = " \t\n\r\0\x0B" ] )
此函数返回字符串 str 去除首尾空白字符后的结果。如果不指定第二个参数,trim() 将去除这些字符:
.=是PHP 字符串运算符之一,表示串接赋值,即字符串连接。(如:$txt1 = "Hello" $txt1 .= " world!" 现在 $txt1 包含 "Hello world!" )
foreach 语法结构提供了遍历数组的简单方式。foreach 仅能够应用于数组和对象,如果尝试应用于其他数据类型的变量,或者未初始化的变量将发出错误信息。
switch 语句类似于具有同一个表达式的一系列 if 语句。很多场合下需要把同一个变量(或表达式)与很多不同的值比较,并根据它等于哪个值来执行不同的代码。这是 switch 语句的用途。

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
