How to Explode Comma-Delimited Strings into Arrays in PHP?

Exploding Comma-Delimited Strings into Arrays

For many programming tasks, it is necessary to split comma-delimited strings into arrays. This can be accomplished with the explode function.

How to Use explode

The syntax for explode is as follows:

explode(separator, string)

where:

• separator is the character or string used to separate the elements in the string.
• string is the string to be split.

Example

For instance, the following code demonstrates how to split the comma-delimited string "9,[email protected],8" into an array:

$myString = "9,[email protected],8";
$myArray = explode(',', $myString);
print_r($myArray);

Output:

Array
(
    [0] => 9
    [1] => [email protected]
    [2] => 8
)

Beware of CSV Files

It is important to note that if the comma-delimited string comes from a CSV file, it is strongly advised to use the str_getcsv function instead, as it handles CSV-specific issues more effectively.
