我在计算foreach循环内部两天之间的差异。
foreach ($result as $key => $value) {
# code...
//$temp[$value->user_id]=$value->user_id;
$count_dates=daysBetween($value->user_source_history_added,$current_date);
$tmp_array[$count_dates][] = $count_dates;
}
在调试tmp_array时,我得到类似的东西。
Array
(
[0] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
[4] => 0
[5] => 0
[6] => 0
)
[1] => Array
(
[0] => 1
)
[3] => Array
(
[0] => 3
[1] => 3
[2] => 3
[3] => 3
)
)
现在我要计算0,1,2,3,3等的数量。所以现在有7 0&1和1 1&4和4 3&s。 我如何获得所有这些数字的计数,以及如何限制它只得到数组直到数组20?
我试过了:
foreach($tmp_array as $tmp_val)
{
count($tmp_val)
}
但我得到主阵列的数量为3

如果你想把所有东西的数量加在一起:
$count = 0;
foreach($tmp_array as $tmp_subarray)
{
foreach($tmp_subarray as $tmp_val) {
if($count < 20) {
$count++;
}
}
}
如果你想要1s,2s,3s等的数量:
$count = array();
foreach($tmp_array as $tmp_subarray)
{
foreach($tmp_subarray as $tmp_val) {
if($count[$temp_val]) {
$count[$temp_val]++;
} else {
$count[$temp_val] = 1;
}
}
}

这将计算数组的所有值,无论假设值是数组或数字有多少维度。这将一直运行,直到主数组达到$ key == 20。
$total = 0;
function addToTotal($number) {
glob $total;
$total = $total + $number;
}
function countArrayValues($array) {
foreach($array as $key => $value) {
if(is_array ($value) {
countArrayValues($value);
} else {
addToTotal($value);
}
}
}
$mainArray; // <-- your array;
foreach($mainArray as $key => $value) {
if($key <= 20) {
countArrayValues($value);
} else {
break;
}
}
echo $total;

试试这个:
$array_number_of_numbert = array();
foreach($tmp_array as $tmp_val_num => $tmp_val)
{
$array_number_of_numbert[$tmp_val_num]= $tmp_val;
}
for($i = 0; $i <=20; $i++)
{
if(isset($array_number_of_numbert[$i])) echo count($array_number_of_numbert[$i])." ". $i."'s\n";
}

if($count_array<=20){}
这是一个通用的解决方案,它将考虑你的$ temp数组中的任何数字,它会将此数字存储为此数组中的记录
$found_numbers=array();
$results=array();
$count_array=0;
foreach($tmp_array as $first_array)
{ $count_array++;
foreach($first_array as $second_array)
{
if($count_array<=20){
if (in_array($second_array, $found_numbers)) {
$results[$second_array][0]++;
}
else{
array_push($found_numbers,$second_array);
$results[$second_array] = array();
array_push($results[$second_array],1);
}
}
}
}
//获取数组中n号的数量,你只需输入print($ results [n] [0]);
print($results[0][0]); //will give you 7
print($results[n][0]); //will give the record of the number n in your array
