I have a string that looks like this:
$str = "Col1, Col2, Col3";
My question is how can I make it look like this
FORMAT(SUM('Col1'),2),FORMAT(SUM('Col2'),2),FORMAT(SUM('Col3'),2)
I am trying to use implode and explode but it's not working for me.
Here is my attempt:
$sample = "Col1, Col2, Col3";
$test = explode(",", $sample);
$test = "'" . implode("', FORMAT(SUM('", $test) . "), 2";
$sample = "Col1,Col2,Col3";
$test= explode(',',$sample);
$_test = '';
foreach($test as $t){
$_test .= "FORMAT(SUM('$t'),2),";
}
$_test = rtrim($_test,',');
I dont know if you can achiev this using explode, but you for sure can using a foreach loop.
$sample = 'Col1,Col2,Col3';
$result = '';
$parts = explode(',', $sample);
foreach ($parts as $part) {
$result .= 'FORMAT(SUM(' . $part . '), 2)';
$result .= (end($parts) !== $part) ? ', ' : '';
}
This runs over each part of the exploded array and adds the desired string plus a comma if its not the last element.
You can also use array_walk to achieve the requested result:
$sample = 'Col1,Col2,Col3';
$parts = explode(',', $sample);
$str = '';
array_walk($parts, function ($element) use (&$str) {
$str .= 'FORMAT(SUM(' . $element . '), 2), ';
});
$result = rtrim($str, ', ');

I am trying to write some PHP code that will separate words when the are two with "&" and a comma when they are three and the last two with "&"
Something like this
$string = "stack over flow";
Print on screen like this "stack, over & flow";
Hope you noticed the comma and the ampersand.
Then when they are two words
$string = "stack overflow";
print like this echo "stack & overflow";
Here is my code I have been trying, but I am not getting it right:
$string = '1,2';
$list = explode(',',$string);
foreach($list as $row) {
if($list = 2) {
echo ''.$row.' &';
}
}
This should take into account the possibilities of one or more words. If there is more than one word, just remove the last word (using array_pop()) and implode() with , the remaining words.
If there is only 1 word, the result is the same as the original string...
$string = "stack over";
$list = explode(" ", $string);
if ( count($list) > 1 ) {
$last = array_pop($list);
$result = implode(", ", $list) . " & {$last}";
}
else {
$result = $string;
}
To add anchor tags to each word...
$list = explode(" ", $string);
$aTag = '<a href="#">';
if ( count($list) > 1 ) {
$last = array_pop($list);
$result = $aTag.
implode("</a>, {$aTag}", $list) . "</a> & {$aTag}{$last}</a>";
}
else {
$result = $aTag.$string."</a>";
}
echo $result;
thanks Nigel Ren.. you code was really helpfully
but their a correction i made.Here
$string = "stack over flow";
$list = explode(" ", $string);
$aTag = '<a href="#">';
if ( count($list) > 1 ) {
$last = array_pop($list);
$result = $aTag.
implode('</a>, '.$aTag.'', $list) . "</a> & {$aTag}{$last}</a>";
}
else {
$result = $aTag.$string."</a>";
}
echo $result;
thanks
I need to create a new array called ar1 with the items: [Dublin, Budapest, Copenhagen] and ar2 with [Ireland, Hungary, Denmark] after than answer with a string containing each country from the countries-array followed by the corresponding capital. Use the format "country = capital,
* country = capital..."
Check code below but i know that is another way to doing that ex. For loop but can someone explain me how?
$ar1 = ["Dublin", "Budapest", "Copenhagen"];
$ar2 = ["Ireland", "Hungary", "Denmark"];
$ANSWER = $ar2[0] . " = " . $ar1[0] . ", " . $ar2[1] . " = " . $ar1[1]. ", " . $ar2[2] . " = " . $ar1[2];
You should use a foreach and the key.
$ar1 = ["Dublin", "Budapest", "Copenhagen"];
$ar2 = ["Ireland", "Hungary", "Denmark"];
$ANSWER = '';
foreach($ar1 as $key => $capital) {
$ANSWER .= $ar2[$key] . ' = ' . $capital . ', ';
}
echo rtrim($ANSWER, ', ');
... and then rtrim to remove the last ,.

Another way to do it using array_combine()
<?php
$ar1 = ["Dublin", "Budapest", "Copenhagen"];
$ar2 = ["Ireland", "Hungary", "Denmark"];
$result = array_combine($ar2,$ar1);
$ANSWER = '';
$i = 0;
$comma = ', ';
$len = count($result);
foreach($result as $country => $capital) {
if ($i == $len - 1){
$comma='';
}
$ANSWER .= $country . ' = ' . $capital.$comma;
$i++;
}
echo $ANSWER;
DEMO: https://3v4l.org/WGtJ3
Using array_map()
$ar1 = ["Dublin", "Budapest", "Copenhagen"];
$ar2 = ["Ireland", "Hungary", "Denmark"];
$input = array_combine($ar2,$ar1);
$output = implode(', ', array_map(
function ($v, $k) { return sprintf("%s=%s", $k, $v); },
$input,
array_keys($input)
));
echo $output;
DEMO: https://3v4l.org/qps1G
More fast and simple way:
$countries=["Ireland", "Hungary", "Denmark"];
$capitals=["Dublin", "Budapest", "Copenhagen"];
$string=implode(',',array_map(function($country,$capital){ return "$country=$capital";},$countries,$capitals));
var_dump($string);
output:
string(50) "Ireland=Dublin,Hungary=Budapest,Denmark=Copenhagen"
If you've got two related lists in separate variables, it's often easier to transpose them into a single structure first. In PHP, you can do this like so:
$transposed = array_map(null, $ar1, $ar2);
Once they're combined, it's a lot more simple to generate the required output:
echo implode(', ', array_map(function($row) {
return "{$row[1]} = {$row[0]}";
}, $transposed));
Ireland = Dublin, Hungary = Budapest, Denmark = Copenhagen

$updateRoles=array();
$updateRoles["role_name"]="Manager";
$updateRoles["role_description"]="Manages system";
$whereRoles["roleid"]=15;
$sdb->dbUpdate("user_roles",$updateRoles,$whereRoles);
Look at the sample. I got this code snippet from a library. I'm curious, How can I code
dbUpdate function ? Because this function has dynamic parameters. Can you show me a sample regarding functions with dynamic array parameters?
Look at func_num_args(), func_get_arg() and func_get_args().

I solved the problem.
Solution:
function BilgiEkle ($tablo,$data)
{
$tablo = trim($tablo);
$str = "(";
$str2 = "(";
foreach ($data as $key => $value) {
$str = $str . '`' . $key . '`' . ',';
$str2 = $str2 ."'". $value ."'". ',';
}
$str = substr($str, 0, -1);
$str2 = substr($str2, 0, -1);
$str = $str . ")";
$str2 = $str2 . ")";
$sqlifade = "INSERT INTO `$tablo` $str VALUES $str2 ";
$islem=$this->baglan->prepare($sqlifade);
$islem->execute();
return $islem->rowCount();
}
Ex:
$arr=array();
$arr['name']='burhan';
$arr['familyname']='tanis';
bilgiEkle('table1',$arr);
$holder = '';
foreach($fields as $key){
$holder .= $key.', ';
}
echo $holder;
I have the code above, it outputs "a, b, c, "
I want to remove the comma after c.
I tried substr and it is not working.
any help?
That's not how it's done.
$holder = join(', ', $fields)
You can use implode() to join all array elements together :
<?php
$holder = implode(', ', $fields);
echo $holder;
?>
You can use substr like this
$holder = '';
foreach($fields as $key){
$holder .= $key.', ';
}
$newholder=substr($holder, 0, -1);
echo $newholder;
I have a while loop use to write a list. i'd like every element separated with a comma, but write a dot after the last one, not a coma.
Here is my code
$exec = mysql_query($req);
while ($row = mysql_fetch_assoc($exec)){
echo '<strong>'.$row['name'].'</strong>, ';
}
But I don't know how to do that. I tried using count() or end(), but none of these works. A little help would be great !
$html = array();
$exec = mysql_query($req);
while ($row = mysql_fetch_assoc($exec)){
$html[] = '<strong>' . htmlspecialchars($row['name']) . '</strong>';
// --------------------^^^^^^^^^^^^^^^^! (1)
}
$html = implode(', ', $html) . '.';
(1) - Never output data to HTML without escaping it properly.
I like the use the implode function for this :)
$list = array();
$exec = mysql_query($req);
while ($row = mysql_fetch_assoc($exec)){
$list[] = '<strong>'.$row['name'].'</strong>';
}
$string = implode(", " , $list);
echo $string . ".";
HTH
Try this:
$exec = mysql_query($req);
$output = array();
while ($row = mysql_fetch_assoc($exec)){
$output[] = '<strong>'.$row['name'].'</strong>';
}
echo implode(',', $output), '.';
Build the string but don't output. Then, trim off the command and add a fullstop:
$exec = mysql_query($req);
$output = "";
while ($row = mysql_fetch_assoc($exec))
{
$output .= '<strong>'.htmlentities($row['name']).'</strong>, ';
}
if($output) echo rtrim($output, ', ').".";
