2个数组替换的问题哦
1.
怎么样将数组
array('1234', '123');
变成
array('\'1234\'', '\'123\'');
这样的
2.
$find= array('\'1234\'', '\'123\'');
$shuju= array ('1234','12345','123456','1234567','123');
$tihuan= array('\'南风\'', '\'西风\'');
$q = str_replace($find, $tihuan, var_export($shuju, true));
这个$q输出的是array(0=>..省略..)
但是我想要的结果是
南风
12345
123456
1234567
西风

- PHP code
$shuju= array ('1234','12345','123456','1234567','123');//原始数据 foreach($shuju as &$value) // 给每个单元两边加引号 $value = "'$value'"; // $shuju被修改了已经 $find= array('\'1234\'', '\'123\''); $tihuan= array('\'南风\'', '\'西风\'');//替换成的 $q = str_replace($find, $tihuan, $shuju); foreach($q as $value) { echo substr($value, 1, -1); echo "<br>\n"; } <br><font color="#e78608">------解决方案--------------------</font><br>

$ar=array_combine($find,$tihuan); function foo($p){ global $ar; if($ar[$p]) return $ar[$p]; else return $p; } foreach(array_map('foo',$shuju) as $value) { echo $value; echo "<br>"; } <div class="clear"> </div>

Title: Example of using the Array.Sort function to sort an array in C# Text: In C#, array is a commonly used data structure, and it is often necessary to sort the array. C# provides the Array class, which has the Sort method to conveniently sort arrays. This article will demonstrate how to use the Array.Sort function in C# to sort an array and provide specific code examples. First, we need to understand the basic usage of the Array.Sort function.

When programming in PHP, we often need to merge arrays. PHP provides the array_merge() function to complete array merging, but when the same key exists in the array, this function will overwrite the original value. In order to solve this problem, PHP also provides an array_merge_recursive() function in the language, which can merge arrays and retain the values of the same keys, making the program design more flexible. array_merge

In PHP, there are many powerful array functions that can make array operations more convenient and faster. When we need to combine two arrays into an associative array, we can use PHP's array_combine function to achieve this operation. This function is actually used to combine the keys of one array as the values of another array into a new associative array. Next, we will explain how to use the array_combine function in PHP to combine two arrays into an associative array. Learn about array_comb

In PHP programming, array is a very important data structure that can handle large amounts of data easily. PHP provides many array-related functions, array_fill() is one of them. This article will introduce in detail the usage of the array_fill() function, as well as some tips in practical applications. 1. Overview of the array_fill() function The function of the array_fill() function is to create an array of a specified length and composed of the same values. Specifically, the syntax of this function is

The array module in Python is a predefined array, so it takes up much less space in memory than a standard list, and can also perform fast element-level operations such as adding, deleting, indexing, and slicing. In addition, all elements in the array are of the same type, so you can use the efficient numerical operation functions provided by the array, such as calculating the average, maximum, and minimum values. In addition, the array module also supports writing and reading array objects directly into binary files, which makes it more efficient when processing large amounts of numerical data. Therefore, if you need to process a large amount of homogeneous data, you may consider using Python's array module to optimize the execution efficiency of your code. To use the array module, you first need to

In Java programming, array is an important data structure. Arrays can store multiple values in a single variable, and more importantly each value can be accessed using an index. But while working with arrays, some exceptions may occur, one of them is ArrayStoreException. This article will discuss common causes of ArrayStoreException exceptions. 1. Type mismatch The element type must be specified when the array is created. When we try to store incompatible data types into an array, it throws

Java is a very powerful programming language that is widely used in various development fields. However, during Java programming, developers often encounter ArrayIndexOutOfBoundsException exceptions. So, what are the common causes of this anomaly? ArrayIndexOutOfBoundsException is a common runtime exception in Java. It means that when accessing data, the array subscript exceeds the range of the array. Common reasons include
