I'm new to PHP and I tried to print array values vertically but it shows values horizontally. This is the code that I tried. Please help me, guys.
$roomCount = count($_POST["room_nos"]);
for($i=0;$i<$roomCount;$i++) {
foreach($roomsCount as $value){
}
$output.= $roomsCount[$i];
}
echo $output;
Current output is 120122.
But I want it as
120
122
Really waiting for your help.
You can use \n to break line. $output.= $roomsCount[$i] . " \n"; Or as @WesleySmith said:
it might be better to use $output.= $roomsCount[$i] . PHP_EOL;, or, if you're looking to output this in a browser, you might want $output.= $roomsCount[$i] . '<br>';
You need to add break line to your code.
there is some ways which i know and you have to use them on where needed for example using <br> is ok for html but might not gonna work if you are not using php in html codes.
For using in html try this edited code :
$roomCount = count($_POST["room_nos"]);
for($i=0;$i<$roomCount;$i++) {
foreach($roomsCount as $value){
}
$output.= $roomsCount[$i]."<br>";
// edited over here // ."<br>" added to your code
}
echo $output;
For using in JavaScript or jQuery string returns or console.log or other things you can use this code too :
$roomCount = count($_POST["room_nos"]);
for($i=0;$i<$roomCount;$i++) {
foreach($roomsCount as $value){
}
$output.= $roomsCount[$i]."\n";
// edited over here // ."\n" added to your code
}
echo $output;
Also if you are trying to save it on database or using on any API you might need to use this code PHP_EOL like this :
$roomCount = count($_POST["room_nos"]);
for($i=0;$i<$roomCount;$i++) {
foreach($roomsCount as $value){
}
$output.= $roomsCount[$i].PHP_EOL;
// edited over here // .PHP_EOL added to your code
}
echo $output;
I not sure its all things which you can use but its all codes which i knew i hope its resolve your problem.
insert a line break :
$output.= sprintf ("%d<br>",$roomsCount[$i]);
textarea tag, this would fail.sprintf here seems a bit like overkill when concatenation would be simpler
you can also append <pre></pre> html tag to print horizontally in php.
$output .= '<pre>' . $output .'</pre>';
$output.= $roomsCount[$i] . " \n";$output.= $roomsCount[$i] . PHP_EOL;, or, if you're looking to output this in a browser, you might want$output.= $roomsCount[$i] . '<br>';What you use might depend on context, but the main point is that you need to tell your program to output each value on a new line.
