I have list in html text arealike this.
12345
23456
12345
78938
85768
my question, how to get the list and create new array with list format..?
sorry about my english
It's unclear what you mean, exactly, but I am assuming you have a list of numbers, separated by line breaks. In that case, you can do this:
explode("\n", $the_string);
If you need to strip out carriage returns (like on Windows), do this:
explode("\n", preg_replace("/\r/", "", $the_string));
jQuery : Get textarea value and replace new line with comma
var txtval = $.trim($("#txtareaid").val()).replace(/\r?\n/g, ',');
// PASS jQuery variable to PHP
PHP: explode() function to convert string into an array based on comma
$a = txtval;
print_r(explode(',', $a));
First You want to Create Array Then,
Use it
$arr1 = array("12345","23456","12345");
echo "I want need".$arr1[0]."";
Say you submit the form to 1.php
code(1.php)
$text=$_REQUEST['t1'];
$arr=explode("\n", trim($text));//$arr is the array of all the entries in the textarea with name 't1'

I have a text box.
I am enter the value in text box like 12 13 14.
and i am want to convert this into 12,13,14 and then convert it into array and show each separate value.
If your form field asks for the values without a comma, then you will need to explode the POST data by space. What you're doing now is imploding it by comma (you can't implode a string to begin with), and then trying to pass that into a foreach loop. However, a foreach loop will only accept an array.
$ar = explode(' ',$da);
That simple change should fix it for you. You will want to get rid of the peculiar die() after your foreach (invalid syntax, and unclear what you're trying to do there!), and validate your data before the loop instead. By default, if you explode a string and no matching delimiters are found, the result will be an array with a single key, which you can pass into a loop without a problem.
Are you sure you want to expect the user enters data in that particular format? I mean, what if the user uses more than one space character, or separate the numbers actually with commas? or with semicolons? or enters letters instead of numbers? Anyway.. at least you could transform all the spaces to a single space character and then do the explode() as suggested:
$da = trim(preg_replace('/\s+/', ' ', $_POST['imp']));
$ar = explode(' ', $da);
before your foreach().
use explode instead of implode as
The explode() function breaks a string into an array.
The implode() function returns a string from the elements of an array.
and you cannot do foreach operation for a string.
$da=$_POST['imp'];
$ar = explode(' ',$da);
foreach($ar as $k)
{
$q="insert into pb_100_fp (draw_3_fp) values ('".mysqli_real_escape_string($conn, $k)."')";
$rs=mysqli_query($conn, $q);
echo $k.",";
}
then you will get this output
o/p : 12,13,14,
I want to do something with PHP .
I have this list of names :
first
second
third
forth
Now i want to have this :
first,second,third,forth
How can this happen with a little PHP code ?
Assuming that you have those in array
$arr=array('first','second');
$str=implode(",",$arr);
EDIT(assuming each names are on the new line, i will replace \n with ,)
$str=file_get_contents("filename.txt");
$newstr=str_replace("\n",',',$str);
$newstr=trim($newstr, ",");//to remove the last comma
echo $newstr;
i think you text tag based on new line, so try this
first
second
third
forth
$arr = explode("\n", $txt);
echo implode(",",$arr);
every new line consider as a array value.
This is really basic PHP, I can't believe it isn't covered in most tutorials.
$array = file("filename", FILE_IGNORE_NEW_LINES);
$string = implode(',', $array);
I think you're looking for explode, like so http://us2.php.net/explode
array explode ( string $delimiter , string $string [, int $limit ] )
You want to set $delimiter to ' ', $string can be a copy -> paste of your text.txt content.
The best thing to do would be: take the text.txt content and use search-replace to remove new lines and add spaces (or commas), so you go from
ron
john
kahn
to ron, john, kahn, at which point you can import an array for use in php.
I have a textarea in my form where user will enter data line by line. I am processing it using $_POST . I have to separate each line by a comma while echoing it in php
the text area content like this
233
123
abf
4c2
I tried with below code
$array = array($_POST['devices']);
$device = implode(",", $array);
echo $device;
But it not showing commas between each value, rather I will get plain values like
233 123 abf 4c2
How can I show it like
233,123,abf,4c2
All above values are part of the text area,
You can not split a string into an array simply by creating an array().
You need to convert it to an array by splitting the lines:
$devices = preg_split('/\s+/', $_POST['devices']);
echo implode(',', $devices');
Note: You may want to split strictly on line endings. But the above will get you started.
No need to summon the power of regular expressions. You can simply implode the results of an explode.
$str = implode(",", explode("\n", $_POST['devices']));
I'm trying to figure out how to convert html textarea into php array,
I've used a form with POST to deliver the query to the php script,
and the php file is getting them with the following line:
$ids = array($_POST['ids']);
Needless to say that it puts everything into one line
Array ( [0] => line1 line2 line3 line4 )
I need the final results to replace this:
$numbers = array(
"line1",
"line2",
"line3",
"line4"
);
What would be the best approach to divide and re-parse it ?
Using an explode on \n is a proper way to get new lines. keep in mind though that on some platforms the end of line is actually send by \r\n, so just exploding on \n could leave you with extra data on the end of each line.
My suggestion would be to remove the \r before exploding, so you dont have to loop through the entire array to trim the result. As a last improvement, you dont know that there actually is a $_POST['ids'], so always check it first.
<?
$input = isset($_POST['ids'])?$_POST['ids']:"";
//I dont check for empty() incase your app allows a 0 as ID.
if (strlen($input)==0) {
echo 'no input';
exit;
}
$ids = explode("\n", str_replace("\r", "", $input));
?>
I would've done the explode by Hugo like this:
$ids = explode(PHP_EOL, $input);
manual Predefined Constants
Just my two cents...
Use this
$new_array = array_values(array_filter(explode(PHP_EOL, $input)));
explode -> convert textarea to php array (that lines split by new line)
array_filter -> remove empty lines from array
array_values -> reset keys of array
If the textarea simply has line breaks per entry then I'd do something like:
$ids = nl2br($_POST['ids');
$ids = explode('<br />',$ids); //or just '<br>' depending on what nl2br uses.
Try with explode function:
$ids = $_POST['ids']; // not array($_POST['ids'])
$ids = explode(" ", $ids);
The first parameter is the delimiter which could be space, new line character \r\n, comma, colon etc. according to your string from the textarea (it's not clear from the question whether values are separated by spaces or by new lines).
For this code i need to take a string like
<b>hey</b> more text<b>hey2</b> other text
and i expect the returned array to look like
<b>hey</b> more text
<b>hey2</b> other text
However it doesnt. How do i make it look like the above? my test code is
$myArr = split("<b>", "<b>hey</b> more text<b>hey2</b> other text");
foreach($myArr as $e)
{
echo "e = $e\n-------------\n";
}
output is
e =
-------------
e = hey</b> more text
-------------
e = hey2</b> other text
I need the b>'s to remain. How should i remove the first empty array?
echo "e = <b>$e\n-------------\n";
You need to prepend the <b> because split removes it from the string.
As for the empty elements of the array try:
$array = array_filter($array);
the "split" function has been deprecated, it is better not to use it.
Instead, use "explode" on <b> and then prepend back onto each element, and pop the first element off the array.
you could use it as you have it and add a $e = "".$e; before the echo
You can add the <b> after splitting, and just pop() the first variable in the array.
