phpバージョン4のmysqlクエリをcsvにエクスポート

Question

オリジナル投稿の編集。私は答えを見つけた!!!!ヘルプ:)

と私は今、コメント欄でこの上の助言に感謝して以下のコードを使用してこの作業を持っている：

<?php 

$f = fopen('incident_csv\test.csv', 'w'); 

$query = " 
select column1, column2, column3 
from table 
where columns = values 
"; 

$var1 = mysql_query($query, $database connection variable); 

/* From Monkey Zeus */ 

$csv_lines = array(); 

// Loop your records from the DB 
while ($row = mysql_fetch_assoc($var1)){ 

$columns = array(); 

// Loop each column for the row 
foreach($row as $k=>$v){ 
// Surround column item in double-quotes and escape double-quotes with double-double-quotes 
$columns[] = '"'.str_replace('"', '""', $v).'"'; 
} 

// Join on a comma 
$csv_lines[] = implode(',', $columns); 
} 

// Create full CSV file by joining on a newline 
$csv_file_string = implode("\n", $csv_lines); 

/* From Monkey Zeus */ 

fwrite($f, $csv_file_string); 

?> 

Answer 1

あなたはこれを行うことができます。

$csv_lines = array(); 

// Loop your records from the DB 
while ($row = mysql_fetch_assoc($var1)){ 

    $columns = array(); 

    // Loop each column for the row 
    foreach($row as $k=>$v){ 
     // Surround column item in double-quotes and escape double-quotes with double-double-quotes 
     $columns[] = '"'.str_replace('"', '""', $v).'"'; 
    } 

    // Join on a comma 
    $csv_lines[] = implode(',', $columns); 

    // Write to the file right away. You are using PHP4 so I imagine system memory is not plentiful 
    // If you use this then there is no need for the "$csv_lines[] =" from above 
    // nor the $csv_file_string after the while loop 
    // fwrite($f, implode(',', $columns)."\n"); 
} 

// fclose($f); // If you choose to write to the file during the while loop then close the file handle when you are finished 

// Create full CSV file by joining on a newline 
$csv_file_string = implode("\n", $csv_lines);

することはでき単にWITE arrayToCsv機能：

function arrayToCsv($array) { 
    $string = array(); 

    foreach ($array as $field) { 
     $string[] = implode(';', $field); 
    } 

    return implode("\n", $string); 
} 

$a = array(
    array('First Field of First Line', 'Second Field of First Line'), 
    array('First Field of Second Line', 'Second Field of Second Line') 
); 
fwrite($f, arrayToCsv($a)); 

しかし、あなたの$fを$f = fopen('file location', 'w');

から設定してください。
