我有這個變量$variable = "own=1,contract_start=1";，我想找到這個變量一個數(shù)組。數(shù)組名稱是 $variables 這是我的數(shù)組：Array([own] => Array ( [type] => bool [value] => 0 )[contr_name] => Array ( [type] => bool [value] => 0 )[all_votes] => Array ( [type] => int [value] => 0 )[contract_start] => Array ( [type] => bool [value] => 0 )[contract_end] => Array ( [type] => bool [value] => 0 )[T] => Array ( [type] => clock [value] => )[a] => Array ( [type] => int [value] => 1 )[candi_ID] => Array ( [type] => int [value] => 1 )[voter_ID] => Array ( [type] => int [value] => 1 )[] => Array ( [type] => [value] => ) )如果該值不等于現(xiàn)有值一個數(shù)組，所以我想用變量值更新該值。這是我的代碼：$variable = "own=1,contract_start=1";function updateTheValue($variables,$variable) { // Split variable looking for into name and value $vars = explode(",", $variable); $match = false; foreach ($vars as $var){ $expbyequal = explode("=", $var); // If this variable is set if ( isset($variables [trim($expbyequal[0])]) ) { // Compare value with stored value if ( $variables [trim($expbyequal[0])]['value'] == trim($expbyequal[1]) ) { $match = true; }else{ $variables[trim($expbyequal[0])] = ["value" => trim($expbyequal[1])]); $match = false; } } } return $match;}$testing = updateTheValue($variables,$variable);任何想法都將是可觀的。

該功能只有幾個小改動。
主要問題是您只是在本地副本中更改變量的值，您需要更改要通過引用傳遞的變量數(shù)組以允許它更新原始數(shù)據(jù)。&在參數(shù)前面添加$variables應該這樣做。
function updateTheValue(&$variables,$variable) {此外，當您設置值時，您將元素設置為僅包含值部分的新數(shù)組，而不是僅更新值，因此將該行更改為...
$variables[trim($expbyequal[0])]["value"]= trim($expbyequal[1]);

您的函數(shù)返回$match，可能是trueor false，它不允許您查看更改。
function updateTheValue(&$variables,$variable) {
// Split variable looking for into name and value
$vars = explode(",", $variable);
$match = false;
foreach ($vars as $var){
$expbyequal = explode("=", $var);
// If this key exists in main keys
if ( in_array(trim($expbyequal[0]), array_keys($variables)) ) {
// Compare value with stored value
if ( $variables [trim($expbyequal[0])]['value'] == trim($expbyequal[1]) ) {
$match = true;
}else{
$variables[trim($expbyequal[0])]["value"] = trim($expbyequal[1]);
$match = false;
}
}
}
return $match;
}
updateTheValue($variables,$variable);
print_r($variables);
使用此功能，您將更改主鍵中存在的鍵的數(shù)據(jù)值。您不需要使用$testing變量，因為引用會&改變您的主數(shù)組。

希望這可以解決您對問題的回答:)
$variable = "own=1,contract_start=1";
function updateTheValue($variables,$variable) {
// Split variable looking for into name and value
$vars = explode(",", $variable);
$match = false;
foreach ($vars as $var){
$expbyequal = explode("=", $var);
// If this variable is set
if (array_key_exists($expbyequal[0],$variables)){
// Compare value with stored value
if ( $variables[trim($expbyequal[0])]['value'] == trim($expbyequal[1])) {
$match = true;
}else{
$variables[trim($expbyequal[0])]['value'] = trim($expbyequal[1]);
$match = false;
}
}
}
return $variables;
}
$variables = updateTheValue($variables,$variable);
echo "<pre>";
print_r($variables);
