PHP Explode() Function - Tutorial And Example

PHP Explode

The PHP explode( ) is used to break a string into an array.

The PHP explode( ) allow us to break a string into a smaller text with each break is represented the same symbol. This symbol is known as a delimiter.

Using the PHP explode( ), we can create an array from string.

Syntax:


explode (separator, string, limit)

explode (separator, string, limit)

Separator: It is required. It specifies where to break the string.
String: It is required. The string to split.
Limit: It is optional. It specifies the number of an array element to return.

Possible Values: Greater than 0: It returns an array with a maximum of elements.

Less than 0: It returns an array except for the last.

0: It returns an array with one element.

Note: We must ensure that the delimiter argument before the string argument.

Example1:


<?php
$str = "PHP explode.";
print_r (explode(" ",$str));
?>

<?php

$str = "PHP explode.";

print_r (explode(" ",$str));

Output:


Array ( [0] => PHP [1] => explode )

Array ( [0] => PHP [1] => explode )

In the above example, we have $str=”PHP explode.”

We made each name as an element of an array and accessed it individually, i.e.,

(explode(” ” ,$str));

Resulting Array Variable:


Array ( [0] => PHP [1] => explode )

Array ( [0] => PHP [1] => explode )

Example2(Limit Parameter):


<?php
$str = ‘PHP explode.';
print_r (explode(' ',$str,0));
print"<br>";
print_r (explode(' ',$str,2));
print"<br>";
print_r (explode(' ',$str,-1));
?>

<?php

$str = ‘PHP explode.';

print_r (explode(' ',$str,0));

print"<br>";

print_r (explode(' ',$str,2));

print"<br>";

print_r (explode(' ',$str,-1));

Output:


Array ( [0] => PHP explode. ) 
Array ( [0] => PHP [1] => explode. ) 
Array ( [0] => PHP )

Array ( [0] => PHP explode. )

Array ( [0] => PHP [1] => explode. )

Array ( [0] => PHP )
