php 怎么把接受到的數(shù)據(jù) 循環(huán)的添加到數(shù)組

遍歷數(shù)據(jù)表，把相應(yīng)的數(shù)據(jù)放到數(shù)組中即可

例如：

?php

//定義一個(gè)數(shù)組，用于保存讀取到的數(shù)據(jù)

$contents = array();

$query = mysql_query("select * from table");

//遍歷數(shù)據(jù)表

while($array = mysql_fetch_array($query)){

$contents[] = $array;

}

print_r($contents);

//然后循環(huán)數(shù)組，或者通過(guò)鍵名使用數(shù)組

foreach($contents as $value){

print_r($value);

}

echo $contents[0]['字段名稱'];

php從數(shù)據(jù)庫(kù)取出的數(shù)據(jù)如何寫(xiě)入一個(gè)新的數(shù)組

數(shù)據(jù)庫(kù)提到的數(shù)據(jù)一般是資源類型的，要逐一讀出，添加到數(shù)組

while($row = mysql_fetch_assoc($res)){

$data[] = $row;

}
