为啥要去掉php 有对应函数
/str_getcsv
昂，已经弄了个php版本的处理了
<?php
function fucking_aliyun_rds($line){
if(!$line) return; $line=(string)$line; $pattern=/^\"\d{1,5}\"/; $int=$replacement=false; if(preg_match($pattern, $line, $matches)){ $int=(int)str_replace(\", \, $matches[0]); }else{ return $line; } if($int){ $replacement = $int; $line=preg_replace(\"", \,$line); $b=preg_replace($pattern, $replacement, $line); } $b.="\t"; return $b;
}
$f = fopen (“wp_users.txt”, “r”);
$ln= 0;
while (! feof ($f)) {
$line= fgets ($f);
/* ++$ln;/
/printf ( $ln);*/
if ($line===FALSE) {
}
else{
$a=fucking_aliyun_rds($line); echo $a;}
}
fclose ($f);
