function getAlabNum($fnum){ $nums = array("0","1","2","3","4","5","6","7","8","9"); $fnums = "0123456789"; for($i=0;$i
去除HTML标记
function text2Html($txt){ $txt = str_replace(" "," ",$txt); $txt = str_replace("",">",$txt); $txt = preg_replace("/[rn]{1,}/isU"," rn",$txt); return $txt; }清除HTML标记
function clearHtml($str){ $str = str_replace('','>',$str); return $str; }相对路径转化成绝对路径
获取指定标记中的内容
function getTagData($str, $start, $end){ if ( $start == '' || $end == '' ){ return; } $str = explode($start, $str); $str = explode($end, $str[1]); return $str[0]; }HTML表格的每行转为CSV格式数组
function getTrArray($table) { $table = preg_replace("']*?>'si",'"',$table); $table = str_replace("",'",',$table); $table = str_replace("","{tr}",$table); //去掉 HTML 标记 $table = preg_replace("']*?>'si","",$table); //去掉空白字符 $table = preg_replace("'([rn])[s]+'","",$table); $table = str_replace(" ","",$table); $table = str_replace(" ","",$table); $table = explode(",{tr}",$table); array_pop($table); return $table;将HTML表格的每行每列转为数组,采集表格数据
function getTdArray($table) { $table = preg_replace("']*?>'si","",$table); $table = preg_replace("']*?>'si","",$table); $table = preg_replace("']*?>'si","",$table); $table = str_replace("","{tr}",$table); $table = str_replace("","{td}",$table); //去掉 HTML 标记 $table = preg_replace("']*?>'si","",$table); //去掉空白字符 $table = preg_replace("'([rn])[s]+'","",$table); $table = str_replace(" ","",$table); $table = str_replace(" ","",$table); $table = explode('{tr}', $table); array_pop($table); foreach ($table as $key=>$tr) { $td = explode('{td}', $tr); array_pop($td); $td_array[] = $td; } return $td_array; }
返回字符串中的所有单词 $distinct=true 去除重复 function splitEnStr($str,$distinct=true) { preg_match_all('/([a-zA-Z]+)/',$str,$match); if ($distinct == true) { $match[1] = array_unique($match[1]); } sort($match[1]); return $match[1]; }
