推薦：php寫入數(shù)據(jù)到CSV文件的方法
本文實例講述了php寫入數(shù)據(jù)到CSV文件的方法。分享給大家供大家參考。具體實現(xiàn)方法如下： ?php$row = 0;ini_set('max_execution_time', 300);$cate;$item;$value;$us;$fp = fopen(torah1.csv, w);if (($handle = fopen(t.csv, r)) !== FALSE) { while (($data = fgetcsv

 本文實例講述了php壓縮和解壓縮字符串的方法。分享給大家供大家參考。具體如下：

下面php代碼通過gzcompress和gzuncompress壓縮和解壓縮字符串，可以設(shè)定壓縮級別

$str = 'Hello I am a very very very very long string'; $compressed = gzcompress($str, 9);//壓縮級別為9 $uncompressed = gzuncompress($compressed); echo $str, "\n"; echo $uncompressed, "\n"; echo base64_encode($compressed), "\n"; echo bin2hex($compressed), "\n"; echo urlencode($compressed), "\n";

希望本文所述對大家的php程序設(shè)計有所幫助。
