PHP Function explode

The PHP explode function is one of the most used PHP functions, at least by me. It is used to turn a string into an array. Let's say you had the following string:

$str = "Pizza, Pork, Ham, Sub, Chicken, Lamb, Rice, Noodles";

You can very easily turn such a string into an array using the PHP explode function like this:

$foods = explode(",", $str);

Now you have the equivalent of this:

$foods = array('Pizza', 'Pork', 'Ham', 'Sub', 'Chicken', 'Lamb', 'Rice', 'Noodles');

Here is a complete PHP example that demonstrates the use of explode:

$str = "Pizza, Pork, Ham, Sub, Chicken, Lamb, Rice, Noodles";

$foods = explode(",", $str);

foreach($foods as $food){

echo $food."<br />";

}

The above example simply uses explode to break the $str string into the $foods array by splitting the string up by the commas.

Arguments

The PHP explode function takes two arguments:

explode('split-by', $string);

  • split-by - can be any value in $string that you want to separate the string into an array by.
  • $string - is the string you want to turn into an array.
