In this example, the explode() function returns an array of the string split by the comma ( ,). The following example uses the explode() function with the a negative $limit argument: $str = 'first_name,last_name,email,phone' 3) Using the PHP explode() function with a negative $limit Also, the last element has the remaining string.

Var_dump($headers) Code language: PHP ( php )Īs shown clearly in the output, the returned array contains three elements specified by the $limit argument.

The following example uses the explode() function with the a positive $limit argument: $str = 'first_name,last_name,email,phone' } Code language: PHP ( php ) 2) Using the PHP explode() function with a positive $limit

The following example uses the explode() function to split a string by a comma ( ,): string( 10) 'first_name' 1) Simple the PHP explode() function example Let’s take some examples of using the explode() function. Starting from PHP 8.0.0, the explode() function throws a ValueError instead. Prior to PHP 8.0.0, the explode() function returns false if the $separator is an empty string. Also, it removes the last $limit elements from the result array. If the $limit is negative, the explode() function splits the $string using the $separator. So the function returns an array with the original string. If the $limit is zero, explode() function interprets it as one. If the $limit is positive, the explode() function returns an array with $limit elements where the last element containing the rest of the string. $limit specifies how the function will return the result array.$separator is the delimiter that the explode() function uses to split the $string.The explode() function has the following parameters:

The following shows the syntax of the explode() function: explode ( string $separator, string $string, int $limit = PHP_INT_MAX ) : array Code language: PHP ( php ) The PHP explode() function returns an array of strings by splitting a string by a separator. Introduction to the PHP explode() function

Here we discuss the introduction to implode function along with the syntax, parameters, and respective examples.Summary: in this tutorial, you’ll learn how to use the PHP explode() function to split a string by a separator into an array of strings. It is a simple function having only 2 parameters where we specify the delimiter to be used to separate the array elements. PHP implode() function as shown in the above examples can be used in various cases where there is a need to join different elements of an input array. It results in a different kind of output where we get the output in the form of 1’s wherever true is present and in place of false, it outputs null i.e empty value. In this example, we are displaying what happens when a boolean set of values are used as array elements.

In the above example, we can see that even objects can be used alongside the implode function but the only condition for this is that the objects should apply the toString() function as shown. It returns an empty string in this case as shown. We are also displaying what happens when an empty array is used. Next, we are using implode function and mentioning the comma separator to use it for separating these 3 strings. In this example, we are first declaring 3 strings as part of an array “arr”. In the second line of output, we have the array output as a combination of the input strings but along with it and the separator parameter is also printed in between two words. So in the first line of output, it prints the array by joining all 3 strings mentioned in the input as it is. In this basic example, we are showing how to use implode function both with and without using the non-mandatory separator parameter. Examples of PHP implodeīelow are some of the examples based on implode function which covers a few possible scenarios where they are or can be implemented: Example #1 From the array elements, it will return the string which is newly joined. Return type: This implode() function returns a string as its output. Note: For backward compatibility, it is always advised to use both the parameters even though the separator is not mandatory.
