Implode, Explode are commonly used functions in PHP. Implode is used to convert array values to a string. While passing parameter we can replace coma(,) by anything like space
Syntax
implode(separator,array)Example
<?php
$my_array=array("My","self","Junaid");
echo implode(' ',$my_array);
?>The output of this example will be
My self JunaidIn the above example, we can see that all comas are replaced by space. we can use this function to a multi-selection option like a checkbox
Explode will help us to convert a string to an array using any separator. explode will help us to separate each value from a string to array value
Syntax
explode(separator,string,limit) Example
<?php
$my_string="My self Junaid";
print_r (explode(" ",$my_string));
?>Output
Array ( [0] => My [1] => self [2] => Junaid ) in the case of Explode, we can set a limit as the third parameter.
These two functions will help us when varus type of form action takes place for example
<?php
$age_limit="18-22";
$ages=explode("-",$age_limit);
$age1=$ages[0];
$age2=$ages[1];The output will be $age1 value will be 18 and $age2 value will be 22.
