[英]Format data output using php
I have the following function which pulls data from the database :我有以下功能从数据库中提取数据:
public function get_dataset() {
$dataset = "";
$data_set = $this->operations_model->get_date();
foreach ($data_set as $value) {
$dataset .= '["' . $value['date'] . '","' . $value['revenue'] . '"],';
}
echo $dataset;
}
And return data in the following format :并以以下格式返回数据:
["2015-10-13 15:53:20","15000.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:54:56","15000.00"],
I would like to format the above data to be in the following format :我想将上述数据格式化为以下格式:
[[2015-10-13 15:53:20,15000.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:54:56,15000.00]]
try this尝试这个
public function get_dataset() {
$dataset = "[";
$data_set = $this->operations_model->get_date();
foreach ($data_set as $value) {
$dataset .= '["' . $value['date'] . '","' . $value['revenue'] . '"],';
}
$dataset = substr($dataset, 0, -1);
$dataset .= "]";
echo $dataset;
}
try:尝试:
public function get_dataset() { $dataset = ""; $comma=''; $data_set = $this->operations_model->get_date(); foreach ($data_set as $value) { $dataset .= $comma.'[' . $value['date'] . ',' . $value['revenue'] . ']'; $comma=','; } echo '['.$dataset.']'; }
