What this article brings to you is a summary of commonly used collection functions in PHP (with code). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
I have been paying attention to the collection program of PHP in the past few days, and found that it is so convenient to use PHP to collect content. I will summarize the frequently used collection functions here for future use!
Get all link content and addresses
function getAllURL($code){ preg_match_all('/<a\s+href=["|\']?([^>"\' ]+)["|\']?\s*[^>]*>([^>]+)<\/a>/i',$code,$arr); return array('name'=>$arr[2],'url'=>$arr[1]); }
Get all image addresses
function getImgSrc($code){ $reg = "/]*src=\"(http:\/\/(.+)\/(.+)\.(jpg|gif|bmp|bnp|png))\"/isU"; preg_match_all($reg, $code, $img_array, PREG_PATTERN_ORDER); return $img_array[1]; }
Current script URL
function getSelfURL(){ if(!empty($_SERVER["REQUEST_URI"])){ $scriptName = $_SERVER["REQUEST_URI"]; $nowurl = $scriptName; }else{ $scriptName = $_SERVER["PHP_SELF"]; if(empty($_SERVER["QUERY_STRING"])) $nowurl = $scriptName; else $nowurl = $scriptName."?".$_SERVER["QUERY_STRING"]; } return $nowurl; }
Convert full-width numbers to half-width numbers
function getAlabNum($fnum){ $nums = array("0","1","2","3","4","5","6","7","8","9"); $fnums = "0123456789"; for($i=0;$i<=9;$i++) $fnum = str_replace($nums[$i],$fnums[$i],$fnum); $fnum = ereg_replace("[^0-9\.]|^0{1,}","",$fnum); if($fnum=="") $fnum=0; return $fnum; }
Remove HTML tags
function text2Html($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 $txt; }
Clear HTML tags
function clearHtml($str){ $str = str_replace('<','<',$str); $str = str_replace('>','>',$str); return $str; }
Convert relative path to absolute path
function relative2Absolute($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 $new_content; }
Get the content in the specified tag
function getTagData($str, $start, $end){ if ( $start == '' || $end == '' ){ return; } $str = explode($start, $str); $str = explode($end, $str[1]); return $str[0]; }
HTML table Convert each row of the HTML table to a CSV format array
function getTrArray($table) { $table = preg_replace("'<td[^>]*?>'si",'"',$table); $table = str_replace("</td>",'",',$table); $table = str_replace("</tr>","{tr}",$table); //去掉 HTML 标记 $table = preg_replace("'<[\/\!]*?[^<>]*?>'si","",$table); //去掉空白字符 $table = preg_replace("'([\r\n])[\s]+'","",$table); $table = str_replace(" ","",$table); $table = str_replace(" ","",$table); $table = explode(",{tr}",$table); array_pop($table); return $table; }
Convert each row and column of the HTML table to an array and collect table data
function getTdArray($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 标记 $table = preg_replace("'<[\/\!]*?[^<>]*?>'si","",$table); //去掉空白字符 $table = preg_replace("'([\r\n])[\s]+'","",$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; }
Return all words in the string $distinct=true to remove duplicates
function splitEnStr($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]; }
