I have a string which I have exploded, it starts like this,
|Crime|Drama|Mystery|Suspense|Thriller|
I would like to remove the first | and the last | after exploding so that the exploded text can look like this
Crime,Drama,Mystery,Suspense,Thriller
is this possible to do?
here is my code so far.
<?php $explodegen = explode("|", $val->Genre); ?>
<?php
foreach($explodegen as $exploding){
echo "".$exploding.",";
}
?>
substr($string, 1, -1);
Then explode it.
You have multiple options then:
trim() the input to strip the | before exploding.
Or array_filter on the result array to have the empty results removed.
If it's just for output use strtr to to transform | into , (and apply trim beforehand).
I'd personally rather extract the strings using preg_match_all("/[^|]+/").
preg_match_all for this use case. It's quite cumbersome: First you have to pass it a reference object to put the result in, then you have to dig into that object's internals to actually get the desired data out.
$input = '|Crime|Drama|Mystery|Suspense|Thriller|';
$delim = '|';
$exploded = explode($delim, trim($input, $delim));
echo implode(',', $exploded);
You should get
Crime,Drama,Mystery,Suspense,Thriller
Lots of ways to do this. Here's one option:
$str = "|Crime|Drama|Mystery|Suspense|Thriller|";
echo $str = str_replace("|", ",", trim($str, "|"));
Result:
Crime,Drama,Mystery,Suspense,Thriller
preg_split with the PREG_SPLIT_NO_EMPTY flag: preg_split('/\|/', $in, PREG_SPLIT_NO_EMPTY);array_filter and explode: array_filter(explode('|', $in));explode and trim: explode('|', trim($in, '|'));Option 1 is the only one that you can do in a single function call. Option 3, however, is the only one that keeps empty elements if they are in the middle of the string.
trim($string, "|") would remove comma from the beginning and end of a string.
and
rtrim($string, "|") would remove comma from the end of a string.
