我有两个数组:
$字段名:
array(
[0] => array(
['fieldName'] =>'id'
['fieldType'] => 'int(11)'
)
[1] =>
['fieldName'] =>'adminID'
['fieldType'] =>'int(11)'
)
[2] =>array(
['fieldName'] =>'schoolID'
['fieldType'] =>'int(11)'
)
[3] => array(
['fieldName'] =>'lessonPlanName'
['fieldType'] =>'varchar(255)'
)
[4] =>array(
['fieldName'] =>'lessonPlanAssignmentDate'
['fieldType'] =>'varchar(255)'
)
[5] =>array(
['fieldName'] =>'lessonPlanDueDate'
['fieldType'] =>'varchar(255)'
)
[6] =>array(
['fieldName'] =>'lessonPlanTopics'
['fieldType'] =>'varchar(255)'
)
[7] =>array(
['fieldName'] =>'lessonPlanDescription'
['fieldType'] =>'text'
)
[8] =>array(
['fieldName'] =>'lessonPlanNotes'
['fieldType'] =>'text'
)
)
$formElementPairs:
array(
['lessonPlanName'] =>'Test'
['lessonPlanAssignedDate'] =>'05/11/2011'
['lessonPlanDueDate'] =>'05/11/2011'
['lessonPlanTopics'] => 1
['lessonPlanDescription'] =>'test'
)
我正在尝试检查数组2是否缺少数组1中的任何’fieldName’键,然后将它们添加到带有空条目的数组2中.以下代码的工作原理是我从第一个数组(id,adminId,schoolId等)获取“fieldName”值,但是当我使用array_keys检查第二个数组时,我得到的数组总是有一个0.还应该提到我在这个项目中使用PHP4.
//merge arrays
for($fn=0; $fn<count($fieldNames); $fn++) {
$thisFieldName = $fieldNames[$fn]['fieldName'];
$fieldCheckArray = array_keys($formElementPairs, $thisFieldName);
//$firephp->fb(count($fieldCheckArray));
}
我是否误解了array_keys和/或是否有更优雅的方法在PHP4中执行此操作?
谢谢
最佳答案 您可以使用array_key_exists检查数组2是否缺少任何内容:
array_key_exists
$missing = array();
for($fn=0; $fn<count($fieldNames); $fn++) {
$thisFieldName = $fieldNames[$fn]['fieldName'];
if(!array_key_exists($thisFieldName, $formElementPairs)) {
$missing[] = $thisFieldName;
}
}
//do something with $missing
