输出(回声/打印)一切从一个PHP数组 [英] Output (echo/print) everything from a PHP Array
问题描述
是否有可能回声或打印一个数组的全部内容,而无需指定数组的哪一部分?
Is it possible to echo or print the entire contents of an array without specifying which part of the array?
场景:我想回应一切从:
The scenario: I am trying to echo everything from:
while($row = mysql_fetch_array($result)){
echo $row['id'];
}
如果不指定身份证,而是输出数组的完整内容。
Without specifying "id" and instead outputting the complete contents of the array.
推荐答案
如果您想格式化输出你自己,只需添加另一个循环(的foreach)通过当前行中的内容进行迭代:
If you want to format the output on your own, simply add another loop (foreach) to iterate through the contents of the current row:
while ($row = mysql_fetch_array($result)) {
foreach ($row as $columnName => $columnData) {
echo 'Column name: ' . $columnName . ' Column data: ' . $columnData . '<br />';
}
}
或者,如果你不关心格式,则使用在previous答案推荐的print_r功能。
Or if you don't care about the formatting, use the print_r function recommended in the previous answers.
while ($row = mysql_fetch_array($result)) {
echo '<pre>';
print_r ($row);
echo '</pre>';
}
的print_r()仅打印键和阵列的值,相对的var_dump()伟驰也打印类型的阵列中的数据,即字符串,整数,双,等等。如果你真的关心数据类型 - 过度的print_r用var_dump()()
print_r() prints only the keys and values of the array, opposed to var_dump() whichs also prints the types of the data in the array, i.e. String, int, double, and so on. If you do care about the data types - use var_dump() over print_r().
