thinkphp a two-dimensional array into a label applicable one-dimensional array method summary, thinkphp dimension

This paper summarizes the one-dimensional array method that thinkphp a two-dimensional array into a label. Share to everyone for your reference. The implementation method is as follows:

Method One:

Copy the code as follows: $projectList =arr1tag ($projectList, Array (', ' Please select '), ' project_name ');

Where $list is a two-dimensional array that passes values, $default as the default, $k to the specified table field.
function Arr1tag ($list, $default = ', $k = ') {
$tmp = ";
if (array ($list)) {
if (array ($default)) {
$tmp [$default [0]]= $default [1];
}
foreach ($list as $k 1=> $v 1) {
$tmp [$k 1+1]= $v 1[$k];
}
}
return $tmp;
}
Method Two:

The

copy Code code is as follows: $projectList =arr2tag ($projectList, Array (', ' Please select '), ');

//Get the corresponding value according to the array subscript
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;
}
//Converts an array from the database to an array that can use the template label, where $default is the default value, $k the specified table field
function Arr2tag ($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;
}
Method Three:

Converts the contents of the read database directly into a one-dimensional array, which is mostly used for select labels
Copy the code as follows: $this->where ($where)->getfield (' Id,name ');
The resulting content is
Array
' id ' = ' name ',
)

It is hoped that this article will be helpful to everyone's thinkphp framework design.

How to use the thinkphp program to change such a two-dimensional array to one-dimensional array

Do not understand, your one-dimensional array want to achieve what effect, it is best to simulate, so that everyone can help you better answer.
Your supplement is the same as the previous effect!
