如何在PHP中合并CSV行

标签: php csv merge

我的CSV文件类似于:

  

Andrew Smith,andy @ hotmail.co.uk,英国曼彻斯特(Martin Jones),Martin Jones,   martin@gmail.com,英国雷丁    Shirley Andrews,洛杉矶,
   Bob James,bobjames @ yahoo.com,

Jacob Costelloe,jc @ email.com,澳大利亚悉尼
   Shirley Andrews,shirley @mail.com,美国
Callum Jones,callumjjones @ btinternet.com,法国巴黎
   Bob James,英国伦敦

基于第一列(名称),我需要合并数据,所以从这里返回我会得到:

  

Andrew Smith,andy @ hotmail.co.uk,英国曼彻斯特(Martin Jones),Martin Jones,   martin@gmail.com,英国雷丁    Bob James,bobjames @ yahoo.com,英国伦敦
Jacob Costelloe,jc @ email.com,澳大利亚悉尼
   Shirley Andrews,shirley @mail.com,洛杉矶,美国
Callum Jones,callumjjones @ btinternet.com,法国巴黎

在PHP中有一种简单的方法吗?

正如您所看到的,输出将两个Bob James联系在一起。     

$text = "Andrew Smith, andy@hotmail.co.uk, Manchester, UK
Martin Jones, martin@gmail.com, Reading, UK
Shirley Andrews, , Los Angeles,
Bob James, bobjames@yahoo.com, ,
Jacob Costelloe, jc@email.com, Sydney, Australia
Shirley Andrews, shirley@mail.com, , US
Callum Jones, callumjjones@btinternet.com, Paris, France
Bob James, , London, UK";

$people = array();
foreach( explode( "\n", $text) as $line)
{
    $entries = explode( ',', $line);
    $entries = array_map( 'trim', $entries);
    list( $first_name, $last_name) = explode( ' ', $entries[0]);

    if( isset( $people[ $last_name ][ $first_name ])) {
        $people[ $last_name ][ $first_name ] = array_merge( $people[ $last_name ][ $first_name ], array( 
            'first_name' => $first_name,
            'last_name' => $last_name,
            'email' => $entries[1],
            'city' => $entries[2],
            'country' => $entries[3]

        ));

    } else {

        $people[ $last_name ][ $first_name ] = array( 
            'first_name' => $first_name,
            'last_name' => $last_name,
            'email' => $entries[1],
            'city' => $entries[2],
            'country' => $entries[3]
        );
    }
}

var_dump( $people);

这将格式化您描述的文字:

$text = str_replace("\r", '', $text);

$container = explode("\n", $text);
$rows = array();

foreach ($container as $data) {
    $values = array_map('trim', explode(',', $data));

    $id = strtolower(trim($values[0]));

    if ($id) {                                
        if (true == isset($rows[$id])) {
            //remove blank
            $values = array_filter($values);

            foreach ($values as $i => $value) {
                if ($rows[ $id ][ $i ] == '') {
                   $rows[ $id ][ $i ] = $value;
                }
            }
       } else {
            $rows[ $id ] = $values;
       }
    }
}
