I am trying to sort an associative array in ascending in order and then transfer it to a HTML table and I am currently stumped at an error. I looked for guidelines here on SO and followed instructions on some posts:
PHP display associative array in HTML table
But still no luck, here is my attempt:
<?php
function format($g){
array_multisort($g, SORT_ASC);
echo "<table>";
foreach($g as $key=>$row) {
echo "<tr>";
foreach($row as $key2=>$row2){
echo "<td>" . $row2 . "</td>";
}
echo "</tr>";
}
echo "</table>";
}
$bib = array("Luke"=>"10",
"John"=>"30",
"Matt"=>"20",
"Mark"=>"40");
format($bib);
?>
My debugger is telling me there is an error at my for each loop but I don't see how it is wrong unless there is some syntax error that I am not seeing? The error is saying Invalid argument supplied for foreach()
Because your $bib
is only single array but you use two foreach
to loop this array
At 2nd loop, your $row
variable is a string, you can't use foreach
for this type
Can you try that for single array ?
<?php
function format($data) {
array_multisort($data, SORT_ASC);
echo "<table>";
foreach($data as $k => $v) {
echo "<tr>";
echo "<td>$k</td>";
echo "<td>$v</td>";
echo "</tr>";
}
echo "</table>";
}
$bib = array("Luke"=>"10",
"John"=>"30",
"Matt"=>"20",
"Mark"=>"40");
format($bib);
?>
$k
is Luke
John
Matt
and Mark
, $v
is 10
30
20
and 40
You can see the foreach example here: http://php.net/manual/en/control-structures.foreach.php
Hope this helpful ^^
You can try this
<?php
function format($data){
array_multisort($data, SORT_ASC);
echo "<table>";
foreach($data as $key => $row) {
echo "<tr>";
echo "<td>" . $key . "</td>";
echo "<td>" . $row . "</td>";
echo "</tr>";
}
echo "</table>";
}
$bib = array(
"Luke"=>"10",
"John"=>"30",
"Matt"=>"20",
"Mark"=>"40"
);
format($bib);
?>
