eval函数,一具字符串转义,极为痛苦,请好汉出手相助
下述代码,无误,可正确输出一个href当点击之时便可弹出111
<?php<br /><br />$tb='';<br /> $wcHead='$tb.=\'<tr>';<br /> $wcTable='';<br /> $wcFoot='</tr>\';';<br /><br />$t='1111111fdddd';<br />$wcTable='<td><a href="#" onClick="alert(111);">test</a></td>';//---------注意此处<br />$wc=$wcHead.$wcTable.$wcFoot;<br />eval($wc);<br /><br />echo $tb;<br />?>
Copy after login
但是,我要实现 的是:一点击,便弹出$t='1111111fdddd';这个变量的值,如何实现??以下是错误之法:
$wcTable='
$wcTable='
------解决方案--------------------
$wcTable=<<<html<br /><td><a href="#" onClick="alert(\'$t\');">test</a></td><br />html;
Copy after login
------解决方案--------------------
<?php<br /> <br />$tb='';<br /> $wcHead='$tb.=\'<tr>';<br /> $wcTable='';<br /> $wcFoot='</tr>\';';<br /> <br />$t='1111111fdddd';<br />$wcTable='<td><a href="#" onClick="alert("'.$t.'");">test</a></td>';//--------- 还是 注意此处<br />$wc=$wcHead.$wcTable.$wcFoot;<br />eval($wc);<br /> <br />echo $tb;<br />?>
Copy after login
------解决方案--------------------
哪里不行? 弹出 1111111fdddd 不正是你想要的吗
