pg_fetch_row

pg_fetch_row

(PHP 4, PHP 5)

pg_fetch_row提取一行作为枚举数组

说明

array pg_fetch_row ( resource $result , int $row )

pg_fetch_row() 根据指定的 result 资源提取一行数据(记录)作为数组返回。每个得到的列依次存放在数组中,从偏移量 0 开始。

返回的数组和提取的行相一致。如果没有更多行可提取,则返回 FALSE

Example #1 pg_fetch_row() 例子

<?php
$conn 
pg_pconnect("dbname=publisher");
if (!
$conn) {
    echo 
"An error occured. ";
    exit;
}

$result pg_query($conn"SELECT * FROM authors");
if (!
$result) {
    echo 
"An error occured. ";
    exit;
}

while (
$row pg_fetch_row($result$i)) {
  for (
$j=0$j count($row); $j++) {
    echo 
$row[$j] . "&nbsp;";
  }

  echo 
"<br /> ";

}
?>

Note:

从 4.1.0 开始,row 成为可选参数。每次调用 pg_fetch_row(),内部的行计数器都会加一。
