把每次都要执行的部分抽出来
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){<br />	<br />	$tb='';<br />		$showArr=array();<br />		$q=$this->getAll3($sql);<br />		while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {<br />				$tb.='<tr><td>'.$r["number"].'</td>';<br />				$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;<br />				$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;<br /><br /><br />		}<br />		return $tb;		<br />}<br />function wc2($sql){<br />	<br />	$tb='';<br />		$showArr=array();<br />		$q=$this->getAll3($sql);<br />		while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {<br />				$tb.='<tr><td>'.$r["number"].'</td>';<br />				$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;<br />				$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;<br />				$tb.=isset($this->show["name"])?'<td>'.$r["name"].'</td>':NULL;<br />				$tb.=isset($this->show["wc"])?'<td>'.$r["wc"].'</td>':NULL;//----------------此处有变化<br /><br />		}<br />		return $tb;		<br />}<br />function wc3($sql){<br />	<br />	$tb='';<br />		$showArr=array();<br />		$q=$this->getAll3($sql);<br />		while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {<br />				$tb.='<tr><td>'.$r["number"].'</td>';<br />				$tb.=isset($this->show["customer"])?'<td>'.$r["customer"].'</td>':NULL;<br />				$tb.=isset($this->show["orderNo"])?'<td>'.$r["orderNo"].'</td>':NULL;<br />				$tb.=isset($this->show["name"])?'<td>'.$r["name"].'</td>':NULL;<br />				$tb.=isset($this->show["fsaww"])?'<td>'.$r["sfs3"].'</td>':NULL;//----------------此处有变化<br /><br />		}<br />		return $tb;		<br />}


------解决方案--------------------
function wc($sql){<br />  $tb='';<br />  $showArr=array();<br />  $q=$this->getAll3($sql);<br />  $dict = array('fsaww' => 'sfs3'); //这里是对照表<br />  while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {<br />    $tb.='<tr><td>'.$r["number"].'</td>';<br />    foreach($this->show as $k) {<br />      if(isset($dict[$k])) $k = $dict[$k];<br />      $tb.='<td>'.$r[$k].'</td>';<br />    }<br />  }<br />  return $tb;        <br />}

------解决方案--------------------
<?php <br />function wc1($sql, $assoc = array()){<br><br>	$tb='';<br>	$showArr = array();<br>	$q=$this->getAll3($sql);<br>	while ($r=$q->fetch_array(MYSQLI_USE_RESULT)) {<br>		$tb.='<tr>
<td>'.$r["number"].'</td>';<br>		if(count($assoc)){<br>			foreach($keys as $k => $v){<br>				$tb .= isset($this->show[$k]) ?'<td>'.$r[$v].'</td>':NULL;<br>			}<br>		}<br>	}<br>	return $tb;<br>}<br><br>wc1($sql, array('customer' => 'customer', 'orderNo' => 'orderNo'));<br>wc1($sql, array('customer' => 'customer', 'orderNo' => 'orderNo', 'name' => 'name', 'wc' => 'wc'));<br>wc1($sql, array('customer' => 'customer', 'orderNo' => 'orderNo', 'name' => 'name', 'fsaww' => 'sfs3'));<div class="clear">
                 
              
              
        
            </div>
</tr>
