左手拿着MOTOLOLA右手拿着NOKIA,要多潇洒,有多潇洒,哈哈,终于学会了,但是可能这个时候,又会有人不经意的拍拍肩膀对你说:哥们,别高兴的太早,你还是菜鸟,离学会还差着一大截呢! 移除 HTML 标签
- $text = strip_tags($input, "");
复制代码 前往 $start 和 $end 之间的文本- function GetBetween($content,$start,$end){ $r = explode($start, $content); if (isset($r[1])){ $r = explode($end, $r[1]); return $r[0]; } return ''; }
复制代码 将url转换成链接- $url = "Jean-Baptiste Jung (http://www.webdevcat.com)"; $url = preg_replace("#http://([A-z0-9./-]+)#", '<a href="http://www.catswhocode.com/blog/$1" style="font-size: 12px; vertical-align: baseline; background-color: transparent; margin: 0px; padding: 0px; color: #3777af; text-decoration: none; font-weight: bold">$0</a>', $url);
复制代码 切分字符串为140个字符- function split_to_chunks($to,$text){ $total_length = (140 - strlen($to)); $text_arr = explode(" ",$text); $i=0; $message[0]=""; foreach ($text_arr as $word){ if ( strlen($message[$i] . $word . ' ') <= $total_length ){ if ($text_arr[count($text_arr)-1] == $word){ $message[$i] .= $word; } else { $message[$i] .= $word . ' '; } } else { $i++; if ($text_arr[count($text_arr)-1] == $word){ $message[$i] = $word; } else { $message[$i] = $word . ' '; } } } return $message; }
复制代码 删除字符串中的URL
- $string = preg_replace('/\b(https?ftpfile):\/\/[-A-Z0-9+&@#\/%?=~_$!:,.;]*[A-Z0-9+&@#\/%=~_$]/i', '', $string);
复制代码 将字符串转成SEO友爱的字符串
- function slug($str){ $str = strtolower(trim($str)); $str = preg_replace('/[^a-z0-9-]/', '-', $str); $str = preg_replace('/-+/', "-", $str); return $str; }
复制代码
解析 CSV 文件
- $fh = fopen("contacts.csv", "r"); while($line = fgetcsv($fh, 1000, ",")) { echo "Contact: {$line[1]}"; }
复制代码 字符串搜刮- function contains($str, $content, $ignorecase=true){ if ($ignorecase){ $str = strtolower($str); $content = strtolower($content); } return strpos($content,$str) ? true : false; }
复制代码 反省字符串是不是以某个串入手下手- function String_Begins_With($needle, $haystack { return (substr($haystack, 0, strlen($needle))==$needle); }
复制代码 从字符串中提取email地址- function extract_emails($str){ // This regular expression extracts all emails from a string: $regexp = '/([a-z0-9_\.\-])+\@(([a-z0-9\-])+\.)+([a-z0-9]{2,4})+/i'; preg_match_all($regexp, $str, $m); return isset($m[0]) ? $m[0] : array(); } $test_string = 'This is a test string... test1@example.org Test different formats: test2@example.org; <a href="test3@example.org">foobar</a> <test4@example.org> strange formats: test5@example.org test6[at]example.org test7@example.net.org.com test8@ example.org test9@!foo!.org foobar '; print_r(extract_emails($test_string));
复制代码 [PHP]代码- function extract_emails($str){ // This regular expression extracts all emails from a string: $regexp = '/([a-z0-9_\.\-])+\@(([a-z0-9\-])+\.)+([a-z0-9]{2,4})+/i'; preg_match_all($regexp, $str, $m); return isset($m[0]) ? $m[0] : array(); } $test_string = 'This is a test string... test1@example.org Test different formats: test2@example.org; <a href="test3@example.org">foobar</a> <test4@example.org> strange formats: test5@example.org test6[at]example.org test7@example.net.org.com test8@ example.org test9@!foo!.org foobar '; print_r(extract_emails($test_string));
复制代码
根据功能来进行封装等。很多的不懂,在使用搜索引擎查找,或者请教老师和在老师详细的讲解、指导下,都能顺利解决。 |
