This is done because the two functions are similar in that they are converting strings into groups.

[PHP source code reading] explode and implode functions, explodeimplodeexplode and implode functions are mainly used for string-Array Operations. for example, after obtaining a parameter, a string is split based on a specific character, [PHP source code reading] explode and implode functions
Problems easily overlooked when using explode to split strings in php 1. explode method description
The explode method splits a string into arrays based on a string as a boundary point.
array explode ( string $delimiter , string $string [, int $limit ] )1
Returns an array composed of strings. each element is a substr
We are learning1. The format of PHP function explode is as follows:
Array explode (string separator, string, [int limit]);
2. The separator in the parameter is the separator, the string is the string to be split, and the limit is the maximum number of elements in the returned array.
Example of PHP function explode:
PHP splits and connects strings using functions such as explode (), implode (), and join (), and explodeimplodePHP uses functions such as explode (), implode (), and join () to separate and connect strings.
Generally, we want to view each part of the string. For example, you can view words in a sentence (for example, spelling check), or split a domain name or email address into component parts. PHP provi
The following is a PHP function written according to the explode () function that splits the split string, and the main PHP intercepts the intermediate data at the beginning and end, which is useful
The code is as follows:

PHP Implode/explode, serialize, JSON, msgpack performance comparison
First use implode, serialize, Json_encode, Msgpack_pack to create four text files for testing.
Create the following code:
Build after creation
Implode.txt 92 bytesSerialize.txt 165 bytesJson.txt 223 bytesMsgpack.txt 121 bytes
The resulting string size is sorted as follows implode
If the array is simple, then json_encode may be smaller than serialize
For example:
$arr = Array (' On
1.explode Method Description
The Explode method allows a string to be split into groups by one string as a boundary point.
Array explode (string $delimiter, string $string [, int $limit])
Returns an array of strings, each of which is a substring of string, separated by the delimiter as the boundary point.

See the two functions.Implode function:Use the implode function to convert an array to a string.Explode function:Use the function explode to convert a string to an array.Example 1.Today, I saw a post in the php forum asking my friend how to convert a string into an array. As a new php programmer, the first response is to think of explode (), implode () these two functions. The new one is also converted to a
[PHP source reading]explode and implode functions, Explodeimplode
The explode and implode functions are primarily used as string-array operations, such as taking a parameter to split a string based on a character, or using one word to match the result of an array and outputting it as a string. These two functions are often used in PHP, so it is necessary to understand their rationale.
This article mainly introduces the usage analysis of substr () and explode () functions in PHP, and describes in detail how substr () and explode () functions process strings in the form of instances, it is a function that is frequently used in string operations and has some practical value. if you need it, you can use the substr () and explode () functions in PH
At one level, the explode and split functions in php are used to split characters into arrays. However, there are still differences between explode and split, next I will introduce it to you.
First, let's take a look at the definitions of the two methods:
Function prototype: array split (string $ pattern, string $ string [, int $ limit])
Function prototype: array explod
Objective
The reason for doing this is because the two functions are very similar in that they are converting strings into groups.
Explode
As can be seen from the following example, the resulting array is in the corresponding order.
$pizza = "Piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = Explode ("", $pizza); Echo $pieces [0]; Piece1echo $pieces [1]; piece2//example 2$data = "foo:*:1023:1000::/hom
The explode () function in PHP is to split another string with one string and return an array of strings. The implode () function returns a string that is composed of array elements. The two functions are between the strings and the array
function of mutual conversion.
First, from the usage point of view, one is to concatenate the array elements into a string, one to divide the string into the array. So it's different from the usage.
