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:
|
1 2 3 |
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:
|
1 2 3 4 5 6 |
<?php $str = "PHP explode."; print_r (explode(" ",$str)); ?> |
Output:
|
1 2 3 |
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:
|
1 2 3 |
Array ( [0] => PHP [1] => explode ) |
Example2(Limit Parameter):
|
1 2 3 4 5 6 7 8 9 10 |
<?php $str = ‘PHP explode.'; print_r (explode(' ',$str,0)); print"<br>"; print_r (explode(' ',$str,2)); print"<br>"; print_r (explode(' ',$str,-1)); ?> |
Output:
|
1 2 3 4 5 |
Array ( [0] => PHP explode. ) Array ( [0] => PHP [1] => explode. ) Array ( [0] => PHP ) |
