    ▪PHP 长文章分页函数 带使用方法，不会分割段落,翻页在底部       代码如下: <?php function ff_page($content,$page) { global $expert_id; $PageLength = 2000; //每页字数 $CLength = strlen($content); $PageCount = floor(($CLength / $PageLength)) + 1; //计算页数 $PageArray=array(); $Seperator = array("\n".........

    ▪Wordpress php 分页代码       效果: 将下面的函数放到你的主题的 functions.php 文件中: 代码如下: function theme_echo_pagenavi(){ global $request, $posts_per_page, $wpdb, $paged; $maxButtonCount = 9; //显示的最多链接数目 if (!is_single()) { if(!is_cat.........

    ▪PHP字符串 ==比较运算符的副作用       代码如下: $a = '212345678912000005'; $b = '212345678912000001'; var_dump($a == $b); 这段代码的输出是bool(true), 说明这样判断会得出结论是两者相等. 类似的特性在in_array()函数第3个参数为false或者不设置的.........

代码如下:

<?php function ff_page($content,$page)
{
global $expert_id;
$PageLength = 2000; //每页字数
$CLength = strlen($content);
$PageCount = floor(($CLength / $PageLength)) + 1; //计算页数
$PageArray=array();
$Seperator = array("\n","\r","。","！","？","；","，","”","'"); //分隔符号

//echo "页数：".$PageCount."<br>";
//echo "长度：".$CLength."<br><br><br>";
//strpos() 函数返回字符串在另一个字符串中第一次出现的位置
if($CLength<$PageLength)
{
echo $content;

}else{

$PageArray[0]=0;
$Pos = 0;
$i=0;
//第一页
for($j=0;$j<sizeof($Seperator);$j++)
{
//echo $Seperator[$j];
$Pos=strpos($content,$Seperator[$j],$PageArray[$i]+1900);
while($Pos > 0 && $Pos < ($i+1)*$PageLength && $Pos > $i*$PageLength )
{
$PageArray[$i] = $Pos ;
$Pos = strpos($Pos+$PageLength,$content,$Seperator[$j]) ;
}
if($PageArray[$i]>0)
{
$j = $j + sizeof($Seperator) + 1;
}
}

//---
for($i=1;$i<$PageCount-1;$i++){

for($j=0;$j<sizeof($Seperator);$j++)
{
//echo $Seperator[$j];
$Pos=strpos($content,$Seperator[$j],$PageArray[$i-1]+1900);
while($Pos > 0 && $Pos < ($i+1)*$PageLength && $Pos > $i*$PageLength )
{
$PageArray[$i] = $Pos ;
$Pos = strpos($Pos+$PageLength,$content,$Seperator[$j]) ;
}
if($PageArray[$i]>0)
{
$j = $j + sizeof($Seperator) + 1;
}
}
}


//--最后一页
$PageArray[$PageCount-1]=$CLength;

//$page=2;
if($page==1)
{
$output=substr($content,0,$PageArray[$page-1]+2);

}
if($page>1 && $page<=$PageCount)
{
$output=substr($content,$PageArray[$page-2]+2,$PageArray[$page-1]-$PageArray[$page-2]);
$output=" （上接第".($page-1)."页）\n".$output;
}

echo str_replace("\n","<br>   ",$output);
//if($page==$PageCount)
//return $output=substr($content,$PageArray[$page-2]+2,$PageArray[$page-1]-$PageArray[$page-2]);

if($PageCount>1)
{
echo "<br><br><br><center>";
echo "<font color='ff0000'>".$page."</font>/".$PageCount." 页  ";
if($page>1)
echo "<a href=/blog_article/$PHP_SELF/expert_id/$expert_id/amp;page_t/.html".($page-1).">上一页</a> ";
else
echo "上一页 ";

for($i=1;$i<=$PageCount;$i++)
{

echo "<a href=/blog_article/$PHP_SELF/expert_id/$expert_id/amp;page_t/.html".$i.">[".$i."]</a> ";
}

if($page<$PageCount)
echo " <a href=/blog_article/$PHP_SELF/expert_id/$expert_id/amp;page_t/.html".($page+1).">下一页</a> ";
else
echo " 下一页 ";

echo "</center>";
}
}

}?>

代码如下:

<?php
$content1=''测试文字，尽量长一些，www.";
$current=$_REQUEST['page_t'];
$result=ff_page($content1,$current);
echo $result;
?>

代码如下:

function theme_echo_pagenavi(){
global $request, $posts_per_page, $wpdb, $paged;
$maxButtonCount = 9; //显示的最多链接数目
if (!is_single()) {
if(!is_category()) {
preg_match('#FROM\s(.*)\sORDER BY#siU', $request, $matches);
} else {
preg_match('#FROM\s(.*)\sGROUP BY#siU', $request, $matches);
}
$fromwhere = $matches[1];
$numposts = $wpdb->get_var("SELECT COUNT(DISTINCT ID) FROM $fromwhere");
$max_page = ceil($numposts /$posts_per_page);
if(empty($paged)) {
$paged = 1;
}
$start = max(1, $paged - intval($maxButtonCount/2));
$end = min($start + $maxButtonCount - 1, $max_page);
$start = max(1, $end - $maxButtonCount + 1);
if($paged == 1){
echo "<span>首页</span>";
echo "<span>上一页</span>";
}else{
echo '<a href="'.get_pagenum_link().'"><span>首页</span></a>';
echo '<a href="'.get_pagenum_link($paged-1).'"><span>上一页</span></a>';
}
for($i=$start; $i<=$end; $i++){
if($i == $paged) {
echo "<span page_num on\">[$i]</span>";
} else {
echo '<a href="'.get_pagenum_link($i).'"><span >['.$i.']</span></a>';
}
}
if($paged == $max_page){
echo "<span>下一页</span>";
echo "<span>末页</span> ";
}else{
echo '<a href="'.get_pagenum_link($paged+1).'"><span>下一页</span></a>';
echo '<a href="'.get_pagenum_link($max_page).'"><span>末页</span></a>';
}
echo " 共{$numposts}条记录, {$max_page}页.";
}
}

代码如下:

<?php theme_echo_pagenavi(); ?>

代码如下:

$a = '212345678912000005';
$b = '212345678912000001';
var_dump($a == $b);

代码如下:

} else if (dval1 == dval2 && !zend_finite(dval1)) {
    /* Both values overflowed and have the same sign,
     * so a numeric comparison would be inaccurate */
    goto string_cmp;
