Thinkphp将二维数组变为标签适用的一维数组方法总结,thinkphp维数
本文实例总结了Thinkphp将二维数组变为标签适用的一维数组方法。分享给大家供大家参考。具体实现方法如下:
方法一:
复制代码 代码如下:
$projectList=arr1tag($projectList,array('','请选择'),'project_name');
//其中$list为传值过来的二维数组,$default为默认值,$k为指定的表字段
function arr1tag($list,$default='',$k=''){
$tmp='';
if(array($list)){
if(array($default)){
$tmp[$default[0]]=$default[1];
}
foreach ($list as $k1=>$v1){
$tmp[$k1+1]=$v1[$k];
}
}
return $tmp;
}
方法二:
复制代码 代码如下:
$projectList=arr2tag($projectList,array('','请选择'),'');
//根据数组下标获取对应值
function array_index2val($array,$index=0){
$value='';
if(is_array($array)){
$i=0;
foreach($array as $val){
if($i===$index){
$value=$val;
break;
}
$i++;
}
}
return $value;
}
//把数据库中调出的数组转换成可以使用模版标签的数组,其中$default为默认值,$k为指定的表字段
function arr2tag($arr,$default=NULL,$K=NULL){
$tmp='';
if(is_array($arr)){
if(is_array($default)){
$tmp[$default[0]]=$default[1];
if($type==1){
$tmp[$default[2]]=$default[3];
}
}
foreach ($arr as $key=>$val){
if(is_array($K)){
$tmp[$val[$K[0]]]=$val[$K[1]];
}else{
$tmp[array_index2val($val,0)]=array_index2val($val,1);
}
}
}
return $tmp;
}
方法三:
将读取数据库的内容直接转换为一维数组,该方法大多用于select标签
复制代码 代码如下:
$this->where($where)->getField('id,name');
得出的内容为
array(
'id' => 'name',
)
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。
不大明白,你一维数组希望达成什么效果,最好能模拟出来,以便让大家更好帮你解答。
你的补充跟之前的效果本来就是一样呀!
$re=array();for($i=0;$i

The method of using a foreach loop to remove duplicate elements from a PHP array is as follows: traverse the array, and if the element already exists and the current position is not the first occurrence, delete it. For example, if there are duplicate records in the database query results, you can use this method to remove them and obtain results without duplicate records.

Methods for deep copying arrays in PHP include: JSON encoding and decoding using json_decode and json_encode. Use array_map and clone to make deep copies of keys and values. Use serialize and unserialize for serialization and deserialization.

The performance comparison of PHP array key value flipping methods shows that the array_flip() function performs better than the for loop in large arrays (more than 1 million elements) and takes less time. The for loop method of manually flipping key values takes a relatively long time.

Multidimensional array sorting can be divided into single column sorting and nested sorting. Single column sorting can use the array_multisort() function to sort by columns; nested sorting requires a recursive function to traverse the array and sort it. Practical cases include sorting by product name and compound sorting by sales volume and price.

PHP's array_group_by function can group elements in an array based on keys or closure functions, returning an associative array where the key is the group name and the value is an array of elements belonging to the group.

The best practice for performing an array deep copy in PHP is to use json_decode(json_encode($arr)) to convert the array to a JSON string and then convert it back to an array. Use unserialize(serialize($arr)) to serialize the array to a string and then deserialize it to a new array. Use the RecursiveIteratorIterator to recursively traverse multidimensional arrays.

PHP's array_group() function can be used to group an array by a specified key to find duplicate elements. This function works through the following steps: Use key_callback to specify the grouping key. Optionally use value_callback to determine grouping values. Count grouped elements and identify duplicates. Therefore, the array_group() function is very useful for finding and processing duplicate elements.

Complexity of PHP array deduplication algorithm: array_unique(): O(n) array_flip()+array_keys(): O(n) foreach loop: O(n^2)
