How to combine strings inside foreach into single string PHP

Question

I have code like this

$word = \'foo\';
$char_buff = str_split($word);

foreach ($char_buff as $chars){
    echo var_dump($chars);
}

The out

Answer 1

I would just use implode, much like this: $string = implode('', $char_buff);

Answer 2

Sounds like you are looking for implode() http://php.net/manual/en/function.implode.php

As for the code you posted $chars .= $char; is probably what you were trying to do

Answer 3

So, why do you split it just to make it a string again?

$word='foo'
$char_buff = str_split($word);

$final = array();
foreach ($char_buff as $chars){
    $final[] = $chars;
}

var_dump( implode('', $final) );

Answer 4

str_split() converts a string to an array. There's no need to use this function if you want to keep the whole word.

Answer 5

<?php
$word = 'foo';
$char_buff = str_split($word);

// here is the trick
$length = count($char_buff);
$char_buff[$length] = $word;

foreach ($char_buff as $chars)
{
    echo var_dump($chars);
}
?>

Answer 6

Maybe some of you are looking for this answer. I think var_dump() is no longer necessary for this problem.

<?php 
    if(isset($_POST['test'])){
        $result = '';
        for($x=1;$x<=4;$x++){
            $ans = $_POST['ans'.$x];
            $result .= $ans;
        } 
    echo $result; 
    }
?>

Here is the HTML

<form role="form" method="post" action="<?php echo $url;?>">
	<input type="checkbox" name="ans1" value="A">A 
	<input type="checkbox" name="ans2" value="B">B 
	<input type="checkbox" name="ans3" value="C">C 
	<input type="checkbox" name="ans4" value="D">D 
	<input type="submit" name="test" value="Submit Answer">
</form>
