Hello All,
Here I Want give example of how to use implode and explode in php.
Use of Implode
=> The implode() function returns a string from the elements of an array. separator parameter of implode() is optional.
I give example for it.
$array = array("hello","all","be","happy","always");
$result = implode($array);
echo $result;
it result will be => helloallbehappyalways.
if you can separate array using space then you can write this way
$result = implode(" ",$array);
this result will me => hello all be happy always
you can any of parameter to separate array;
like i give emaple for it
echo $result = implode("$",$array)."<br/>";
echo $result = implode("+",$array)."<br/>";
echo $result = implode("-",$array)."<br/>";
echo $result = implode("*",$array)."<br/>";
this result will me =>
hello$all$be$happy$always
hello+all+be+happy+always
hello-all-be-happy-always
hello*all*be*happy*always
I think yon can understand what implode work it can make string of array using separate
by it parameter.you can use different parameter that can separate it.
Use of Explode
=> this function use of breaks a string into an array.separator parameter cannot be empty string.
i will give example for it.
$string = "Lorem Ipsum is simply dummy text of the printing and typesetting industry";
$result = explode(" ",$string);
print_r($result);
this result will be=>
Array
(
[0] => Lorem
[1] => Ipsum
[2] => is
[3] => simply
[4] => dummy
[5] => text
[6] => of
[7] => the
[8] => printing
[9] => and
[10] => typesetting
[11] => industry
)
if you want to separate to this different word.
if you to get separate word then check below code
echo "<br/>";
$count = count($result);
for($i=1;$i<=$count;$i++){
$line = each($result);
print_r($line);
echo "<br/>";
echo $line['value']."<br/>";
}
this out put will be
=>
Lorem
Array
(
[1] => Ipsum
[value] => Ipsum
[0] => 1
[key] => 1
)
Ipsum
Array
(
[1] => is
[value] => is
[0] => 2
[key] => 2
)
is
Array
(
[1] => simply
[value] => simply
[0] => 3
[key] => 3
)
simply
Array
(
[1] => dummy
[value] => dummy
[0] => 4
[key] => 4
)
dummy
Array
(
[1] => text
[value] => text
[0] => 5
[key] => 5
)
text
Array
(
[1] => of
[value] => of
[0] => 6
[key] => 6
)
of
Array
(
[1] => the
[value] => the
[0] => 7
[key] => 7
)
the
Array
(
[1] => printing
[value] => printing
[0] => 8
[key] => 8
)
printing
Array
(
[1] => and
[value] => and
[0] => 9
[key] => 9
)
and
Array
(
[1] => typesetting
[value] => typesetting
[0] => 10
[key] => 10
)
typesetting
Array
(
[1] => industry
[value] => industry
[0] => 11
[key] => 11
)
industry
if you want to get only word echo $line['value]; use it and print_r($line); comment it.
you can also limit parameter to return a number of array elements
check this example
$string = "Lorem,Ipsum,is,simply,dummy,text,of,the,printing,and,typesetting,industry";
if you want to only 1 key then code this
print_r(explode(',',$string,0));
this result will =>
Array
(
[0] => Lorem,Ipsum,is,simply,dummy,text,of,the,printing,and,typesetting,industry
)
if you want 2 key then
print_r(explode(',',$string,2));
this result will=>
Array
(
[0] => Lorem
[1] => Ipsum,is,simply,dummy,text,of,the,printing,and,typesetting,industry
)
if you want all key then you can use this code
print_r(explode(',',$string,-1));
this result will be =>
Array
(
[0] => Lorem
[1] => Ipsum
[2] => is
[3] => simply
[4] => dummy
[5] => text
[6] => of
[7] => the
[8] => printing
[9] => and
[10] => typesetting
)
this use of explode and implode. explode use for string to array and implode use for array to string.
