Thinkphp Summary of One Dimensional Array Methods Applicable to Changing Two Dimensional Arrays into Labels

This article summarizes Thinkphp's 1-D array method for changing 2-D arrays into labels. Share it for your reference. The specific implementation method is as follows:

Method 1:

$projectList=arr1tag($projectList,array('',' Please select '),'project_name');  

  

// Among them $list For passing values 2 Dimensional array, $default Is the default value, $k For the specified table field   

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;  

}

Method 2:

$projectList=arr2tag($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 template labels, where $default Is the default value, $k For 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 3:

Convert the contents of the read database directly to a 1-dimensional array, which is mostly used for select tags

$this->where($where)->getField('id,name');  

 The content obtained is as follows   

array(  

 'id' => 'name',  

)
