1.采集表格中的內容為數組
function get_td_array($table) {
? ?? ???$table = preg_replace("'<table[^>]*?>'si","",$table);
? ?? ???$table = preg_replace("'<tr[^>]*?>'si","",$table);
? ?? ???$table = preg_replace("'<td[^>]*?>'si","",$table);
? ?? ???$table = str_replace("</tr>","{tr}",$table);
? ?? ???$table = str_replace("</td>","{td}",$table);
? ?? ???//去掉 HTML 標記
? ?? ???$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); //OSPHP.com.CN
? ?? ???foreach ($table as $key=>$tr) {
? ?? ?? ?? ?? ? $td = explode('{td}', $tr);
? ?? ?? ?? ?? ? array_pop($td);
? ?? ?? ?? ?$td_array[] = $td;
? ?? ???}
? ?? ???return $td_array;
} 復制代碼 2.取得某行代碼中間的字符串
/**
+----------------------------------------------------------
* 取得某行代碼之間的字符串
+----------------------------------------------------------
* 例: echo get_innerhtml("<tr><td height=20>something</td></tr>", "td");? ?//will print "something".
+----------------------------------------------------------
*/
function get_innerhtml($html,$label) {
? ? $result_arr = preg_split("/<\/".$label.">/i",$html);
? ? $pattern = "/<".$label.".*?>/i";
? ? for ($i = 0; $i < count($result_arr); $i++) {
? ?? ???list($left, $right) = preg_split($pattern,$result_arr[$i],2);
? ?? ???$result_arr[$i] = $right;
? ? }
? ? return $result_arr;
} 復制代碼 3.獲取Input的HTML代碼中的Value值
//獲取Input的HTML代碼中的Value值
function get_input_value($input) {
? ? $pos = stripos($input, "value=") + 6;
? ? if ($pos !== false) {
? ?? ???$input = substr($input, $pos);
? ?? ???if (substr($input, 0, 1) == "\"")
? ?? ?? ?? ?return substr($input, 1, strpos($input, "\"", 1) - 1);
? ?? ???else
? ?? ?? ?? ?return substr($input, 0, strpos($input, " ") - 1);
? ? }
? ? return false;
} 復制代碼 4.獲取字符串$str中,字符串$a與字符串$b之間的字符串 //獲取字符串$str中,字符串$a與字符串$b之間的字符串
function getcontentbetween($a, $b, $str) {
? ? if ($str!=="" && $a!=="" && $b!=="") {
? ?? ???$start = strpos($str, $a) + strlen($a);
? ?? ???return substr($str, $start, strpos($str, $b, $start + 1) - $start);
? ? }
? ? return false;
} 復制代碼 5.<br>變成回車 function br2nl($text)
{
? ?return??trim(preg_replace('/<br\s*/?'.'>/i', '', $text));
} 復制代碼 6.換行奕成<p></p> function nl2p($text)
{
return str_replace(array("\r\n\r\n","\r\n","\r","\n"),"</p><p>",$text);
} 復制代碼 7.獲得當前腳本網址 function get_php_url(){?
? ?? ???if(!empty($_SERVER["REQUEST_URI"])){?
? ?? ?? ?? ?? ? $scriptName = $_SERVER["REQUEST_URI"];?
? ?? ?? ?? ?? ? $nowurl = $scriptName;?
? ?? ???}else{?
? ?? ?? ?? ?? ? $scriptName = $_SERVER["HP_SELF"];?
? ?? ?? ?? ?? ? if(empty($_SERVER["QUERY_STRING"])) $nowurl = $scriptName;?
? ?? ?? ?? ?? ? else $nowurl = $scriptName."?".$_SERVER["QUERY_STRING"];?
? ?? ???}?
? ?? ???return $nowurl;?
} 復制代碼 8.去除html標記
function Text2Html($txt){
? ?? ???$txt = str_replace("??"," ",$txt);
? ?? ???$txt = str_replace("<","<",$txt);
? ?? ???$txt = str_replace(">",">",$txt);
? ?? ???$txt = preg_replace("/[\r\n]{1,}/isU","<br/>\r\n",$txt);
? ?? ???return $txt;
} 復制代碼 9.相對路徑轉絕對路徑 function relative_to_absolute($content, $feed_url) {?
? ? preg_match('/(http|https|ftp):\/\//', $feed_url, $protocol);?
? ? $server_url = preg_replace("/(http|https|ftp|news):\/\//", "", $feed_url);?
? ? $server_url = preg_replace("/\/.*/", "", $server_url);?
? ? if ($server_url == '') {?
? ?? ???return $content;?
? ? }?
? ? if (isset($protocol[0])) {?
? ?? ???$new_content = preg_replace('/href="\//', 'href="'.$protocol[0].$server_url.'/', $content);?
? ?? ???$new_content = preg_replace('/src="\//', 'src="'.$protocol[0].$server_url.'/', $new_content);?
? ? } else {?
? ?? ???$new_content = $content;?
? ? }?
? ? return $new_content;?
} 復制代碼
10.取得所有鏈接
function get_all_url($code){?
? ?? ???preg_match_all('/<a\s+href=["|\']?([^>"\' ]+)["|\']?\s*[^>]*>([^>]+)<\/a>/i',$code,$arr);?
? ?? ???return array('name'=>$arr[2],'url'=>$arr[1]);?
} 復制代碼
11.獲取指定標記中的內容
function get_tag_data($str, $start, $end){?
? ?? ???if ( $start == '' || $end == '' ){?
? ?? ?? ?? ?? ?return;?
? ?? ???}?
? ?? ???$str = explode($start, $str);?
? ?? ???$str = explode($end, $str[1]);?
? ?? ???return $str[0];?
