数组$results具有以下值。如果数组$results的索引为负值，我想删除[total_ex_tax]索引。需要您的支持。

尝试以下代码：
$x = [
['total_ex_tax' => -214.529296875, 'id'=>1],
['total_ex_tax' => 14.529, 'id'=>2],
];
function custom_filter($a){
if($a['total_ex_tax'] < 0){
return false;
}
return $a;
}
$x = array_filter(array_map('custom_filter',$x));
print_r($x);
您需要结合使用array_filter和array_map
试试这个：
$resultsNew = array();
foreach($results as $result)
{
if(isset($result['total_ex_tax']) && $result['total_ex_tax'] >= 0)
$resultsNew[] = $result;
}
// $resultsNew is our result with non-negative total_ex_tax values
你可以试试这个：
<?php
//supposing that this is your array
$results = array(
[
"service_number" => 0297162222,
"total_ex_tax" => -214.529296875
],
[
"service_number" => 1800152152,
"total_ex_tax" => 16897.69921875
]
);
for ( $num = 0; $num < count($results); $num ++ ) {
foreach ( $results[$num] as $key => $value ) {
//checks value if less than 0
if ( $value < 0 ) {
//removes the array index from the original array
unset($results[$num]);
break; //exits the loop
}
}
}
//resets the index values from the array
$results = array_values($results);
//displays the new result
print_r($results);
结果：
Array
(
[0] => Array
(
[service_number] => 1800152152
[total_ex_tax] => 16897.69921875
)
)
还没有检查过。试试看：
$results = //your array;
foreach($results as $key->$value)
{
if($value['total_ex_tax']!=="" && $value['total_ex_tax']<0){
unset($results[$key]);
}
}
具有array_filter函数的简短解决方案：
$results = array_filter($results, function($v){
return $v['total_ex_tax'] > 0;
});
