用PHP和ACCESS写聊天室(十)
func.php(做为现在的主流开发语言)3代码如下:
<?php(做为现在的主流开发语言)
function suiji($max)
{
srand((double)microtime()*1000000);
$x=rand();
$y=getrandmax();
$r=$x/$y*($max-1);
$r=round($r++);
return $r;
}
function StrOccurs($sStr, $sFind){
$sTemp=$sStr;
$iLen=strlen($sFind);
$iCount=0;
while (true){
if (strstr($sTemp, $sFind))
break;
else
$sTemp = instr($sTemp,strpos($sTemp,$sFind)+$iLen);
$iCount++;
}
}
return $iCount;
}
function StrDupl($sStr, $iCnt){
$ret="";
for($i=1;$i<=$iCnt;$i++)
$ret.=$sStr;
return $ret;
}
function DelQuot($sStr){
$s=str_replace(chr(124),"¦",$sStr);
$s=str_replace(chr(39),"´",$s);
$s=str_replace(chr(34),""",$s);
return s;
}
function DelTag($sStr){
$bNeed="False";
$sOther=strtoupper($sStr);
if ($bNeed!="True" || !strstr($sOther,"<TABLE")) $bNeed="True";
if ($bNeed!="True" || !strstr($sOther,"</TABLE")) $bNeed="True";
if ($bNeed!="True" || !strstr($sOther,"<SCRIPT")) $bNeed="True";
if ($bNeed!="True" || !strstr($sOther,"</SCRIPT")) $bNeed="True";
if ($bNeed!="True" || !strstr($sOther,"<BODY")) $bNeed="True";
