php中,共有3个函数,其中绝大分数是相同的。如何能更科学的变成一个函数,从而搞效率。
方法一:将此3个函数变成一个,怎么实现呢?
方法二:奖此3个函数的执行体,就是输出的部分公共部分,单独做个函数。如何实现呢?????function wc1($sql){
$tb='';
$showArr=array();
$q=$this->getAll3($sql);
while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {
$tb.='<tr><td>'.$r["number"].'</td>';
$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;
$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;
}
return $tb;
}
function wc2($sql){
$tb='';
$showArr=array();
$q=$this->getAll3($sql);
while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {
$tb.='<tr><td>'.$r["number"].'</td>';
$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;
$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;
$tb.=isset($this->show["name"])?'<td>'.$r["name"].'</td>':NULL;
$tb.=isset($this->show["wc"])?'<td>'.$r["wc"].'</td>':NULL;//----------------此处有变化 }
return $tb;
}
function wc3($sql){
$tb='';
$showArr=array();
$q=$this->getAll3($sql);
while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {
$tb.='<tr><td>'.$r["number"].'</td>';
$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;
$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;
$tb.=isset($this->show["name"])?'<td>'.$r["name"].'</td>':NULL;
$tb.=isset($this->show["fsaww"])?'<td>'.$r["sfs3"].'</td>':NULL;//----------------此处有变化 }
return $tb;
}

//或者switch 看自己习惯

$tb.=isset($this->show["fsaww"])?'<td>'.$r["sfs3"].'</td>':NULL;//----------------此处有变化

}简单改了下 楼主参考吧
可以把
$tb.='<tr><td>'.$r["number"].'</td>';
foreach($this->show as $k) {
if(isset($dict[$k])) $k = $dict[$k];
$tb.='<td>'.$r[$k].'</td>';
}
放在外面吗?因为,要多次执行的。
就是动态生成一个
$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;
$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;
$tb.=isset($this->show["name"])?'<td>'.$r["name"].'</td>':NULL;
$tb.=isset($this->show["wc"])?'<td>'.$r["wc"].'</td>':NULL;//-
