I have following array:
array(6) {
[0]=>
string(4) "XXX1"
[1]=>
int(16)
[2]=>
string(4) "YYY1"
[3]=>
string(4) "XXX2"
[4]=>
int(632)
[5]=>
string(4) "YYY2"
}
I would like to have an output like this:
First XXX - First int() - First YYY\n
Second XXX - Second int() - Second YYY\n
How to achieve this using while, for or foreach ?
Thanks.
I don't know exactly what kind of output you're looking for, but this puts it in paragraph tags:
$cnt = 0;
$out = '<p>';
foreach ($arr as $key => $value){
$out .= $value.' - ';
$cnt++;
if ($cnt == 3){
$cnt = 0;
$out = substr($out, 0, -3).'</p><p>';
}
}
$out = substr($out, 0, -3);
Like Pe de Leao, I'm not 100% sure I understand the output you desire, but here are two candidates:
Does not check for a full "set" of 3:
<?php
$flat = array(
"XXX1",
16,
"YYY1",
"XXX2",
632,
"YYY2"
);
for ($i = 0; $i < count($flat); $i += 3)
echo "{$flat[$i]} - {$flat[$i + 1]} - {$flat[$i + 2]}\n";
?>
Does check for a full "set" of 3:
<?php
$flat = array(
"XXX1",
16,
"YYY1",
"XXX2",
632,
"YYY2",
"XXX3",
932
);
for ($i = 0; $i < count($flat) && ($i + 3) < count($flat); $i += 3)
echo "{$flat[$i]} - {$flat[$i + 1]} - {$flat[$i + 2]}\n";
?>
The examples are not fool-proof, for instance they make assumptions such as the array being numerically indexed with no holes, but I hope this is close enough to what you want.
