By nature, PHP provides functions that work to ensure a certain activity or goal is achieved. This makes it simple to work with PHP since you do not need to redefine the function functionality as it is already done in PHP. Functions enable the developer to quickly and easily solve a problem with ease.
In this article, we shall discuss the implode and explode functions in PHP by defining what they do, where they are used, and what is required to use them.
The implode function in PHP is commonly known as an array to string since it collects an array as input data and returns a string as the output data. The implode function is used to join elements in an array with a string.
The syntax of implode function in PHP is as below
separator is an optional parameter and is set to empty by default
array is a required parameter which is the array that will be joined to string
Example of implode function
We first define an array for example
We can convert this array to a string by adding a space inside the words as below
echo implode(" ",$array);
To explain the above,
The " " is the separator that will be included after each array element.
The $array is the array data that will be converted to a string.
The result of the above example will be
this is an implode function
You can add any separator to your array like the ones shown in the examples below
//Example 1 query
//Example 1 result
//Example 2 query
//Example 2 result
//Example 3 query
//Example 3 result
The explode function in PHP does the opposite of implode function where it is used to "Split a string by a specified string into pieces i.e. it breaks a string into an array". Where the implode function forms a string as a result, the explode function takes a string as input and forms an array as the result.
The explode function is used to break a large string into a simpler smaller sizes of text depending on the separator you define.
The syntax for explode function in PHP is
explode (separator, string)
The separator is what separates the string.
For example, for implode example above we added a (-) sign as the separator for the string. In the explode function we have to define it as the separator if we want to obtain back the array we started with.
echo explode ("-",$string);
The result for the above code snippet will be an array
To display the values in this array we can use json_encode function to convert the array into an object so that it can be visible.
echo json_encode(explode ("-",$string));
The result will now be as follows
Please note that you cannot explode a separator that is not present in a string.
In the above article, we have explained what implode function is in PHP, explode function is in PHP. We have also shown the syntax of each function and some examples using each function.
