[英]Adding “and” between last two database results in foreach loop
I want to add the word "and" between the last two MySQL results. 我想在最后两个MySQL结果之间添加单词“and”。 I can add commas but I need to add commas between the first ones and then "and" between the last two.
我可以添加逗号,但我需要在第一个之间添加逗号,然后在最后两个之间添加“和”。
Here is the code I'm using: 这是我正在使用的代码:
$not_first = false;
foreach($solos as $solo)
{
if ($not_first)
{
echo ', ';
}
$not_first = true;
echo $solo->id;
}
I could echo 'and' instead of the comma. 我可以回应'和'而不是逗号。 But if I have 3 or more results it would say "result and result and result and result".
但如果我有3个或更多结果,它会说“结果和结果,结果和结果”。 I want it to say "result, result, result, and result".
我希望它说“结果,结果,结果和结果”。
Any ideas? 有任何想法吗?
Try to use next idea 尝试使用下一个想法
if (count($solos) > 2) {
$last = array_pop($solos);
echo implode(', ', $solos) . ' and ' . $last;
}
else
{
echo implode(' and ', $solos);
}
I'd prefer using for
instead of foreach
in this case: 在这种情况下,我更喜欢使用
for
而不是foreach
:
for($i=0; $i<count($solos); $i++){
echo $solos[$i]->id;
if($i == count($solos) - 2){ // --> second last element, implies "and"
echo " and ";
}
else{
if($i != count($solos) - 1){ // --> "," for all other elements, except last
echo ", ";
}
}
}
Or use this: 或者用这个:
$i = 1;
$last = count($solos);
foreach($solos as $solo)
{
if ($i > 1 && $i != $last)
{
echo ', ';
}
elseif ( $i == $last )
{
echo ' and ';
}
echo $solo->id;
$i++;
}
you can count it and at second last id append "and" instead of "," 你可以数数它,在倒数第二个id附加“和”而不是“,”
$x = count($solos);
foreach($solos as $solo){
echo $solo->id;
if ($solos[$x - 2] == $solo){
echo 'and';
}elseif ($solos[$x -1] != $solo && $solos[0] != $solo){
echo ','
}
}
The other answers work perfectly. 其他答案完美无缺。 For the sake of completeness, you could also insert an "and" using preg_replace.
为了完整起见,您还可以使用preg_replace插入“和”。
$solos = array( 'one', 'two', 'three', 'four' );
$result = implode(', ',$solos);
$result = preg_replace('/, ([^,]+)$/',', and \1', $result);
Over 1 million iterations, mnv's array_pop method took 2.13 seconds. 超过100万次迭代, mnv的 array_pop方法耗时2.13秒。 preg_replace completed in 3.65 seconds.
preg_replace在3.65秒内完成。 Using array_pop would be preferable.
使用array_pop会更好。
