我在PHP中有以下字符串。
"File:content/resources/11933/Calm_Nebula_by_The_Free_Mason.jpgDate:Fri Mar 18 11:30:17 CET 2016Size:23124"
我需要分别获取文件,日期和大小。
提取所需值的最佳方法是什么?
explode() OR substring()
爆炸需要一些共同的价值,子串需要开始和结束。在这两种情况下我都有点混乱。
非常感谢任何帮助。

试试这个:
<?php
$text = "File:content/resources/11933/Calm_Nebula_by_The_Free_Mason.jpgDate:Fri Mar 18 11:30:17 CET 2016Size:23124";
$pattern = '/file:(.*?)date:(.*?)size:(.*)/i';
preg_match($pattern, $text, $out);
print_r($out);
?>
输出:
Array
(
[0] => File:content/resources/11933/Calm_Nebula_by_The_Free_Mason.jpgDate:Fri Mar 18 11:30:17 CET 2016Size:23124
[1] => content/resources/11933/Calm_Nebula_by_The_Free_Mason.jpg
[2] => Fri Mar 18 11:30:17 CET 2016
[3] => 23124
)
