A smooth interplay between different types of variables in PHP can pop up when we write code, which we can achieve with arrays and strings.
These two functions are built-in functions in PHP. You can use them to format your array contents into a string. This new string variable still holds the type of an array.
However, these functions are not entirely different functions of their own.
join() is an alias of the
implode() function. Therefore,
implode() can be replaced with
join() in any usage, and vice versa.
implode(string $separator, array $nameOfArray)
join(), just change
join(), and the rest remains the same.
""), comma (
","), underscore (
"_"), the plus sign (
"+"), pipe sign (
|), and so on.
Note: You can omit the first parameter, but the content of the string will be lumped together as one word.
<?php $index = array('human','high','jump'); //printing array print_r($index); //using implode() and join() to join array items $fine = implode("+",$index); $mine = join($index); print "imploded array with + as separator: $fine\n"; print "joined array with no separator parameter: $mine\n"; ?>
In the code above, we print an array in line 5. In lines 8 and 9, we use the
join() methods to combine array elements. Then, in lines 11 and 12, we return the new strings.
