PHP中extract()函数的妙用

由 橙三吉。 提交于 2020-04-22 02:51:14
近日在看一个牛人的代码时，看到一个非常好用的函数：extract()，它的主要作用是将数组展开，键名作为变量名，元素值为变量值，可以说为数组的操作提供了另外一个方便的工具，比方说，可以很方便的提取$_POST或者$_GET的元素，对表单提交上来的内容不能不用一一赋值，直接使用下面代码： form.html <form action="action.php" method="post"> <input type="text" name="username"> <input type="password" name="password"> <input type="submit"> 在action.php中只要使用extract()函数将$_POST全局数据解开： action.php <?php extract($_POST); //相当于$username = $_POST['username']; //$password = $_POST['password']; ?> 是不是很方便呢？呵呵，下面是PHP手册里的详细解释： extract (PHP 4, PHP 5) extract — 从数组中将变量导入到当前的符号表 说明 int extract ( array $var_array [, int $extract_type [, string $prefix ]] )

fastest way to extract .zip archive

由 。_饼干妹妹 提交于 2020-04-13 06:26:07
问题 Which is the fastest way for extracting .zip archives? Performance of my application is highly based on how fast .zip files are extracted. I am using dotNetzip atm, but it seems that there could be more faster tools. If there is, are they safe? I've heard that QuickLZ is the fastest, but haven't tested it, also haven't found any code samples or how to use it in c#. Any help would be greatly appriciated. 回答1: If upgrading your project to .NET 4.5 is an option, then you can use the ZipArchive

Extract values from a correlation matrix according to their p-value in a second matrix

由 淺唱寂寞╮ 提交于 2020-03-03 10:14:44
问题 I have created a correlation matrix with an external program (SparCC). I have calculated p-values from the same data in SparCC as well and I end up with two objects which I imported into R, let's call them corr and pval and > ncol(corr)==nrow(corr) [1] TRUE > ncol(pval)==nrow(pval) [1] TRUE and > colnames(corr)==rownames(pval) [1] TRUE ... and the same the other way around. Since the matrices (or should I be using data.frame ?) are fairly large (about 1000 items), I would like to extract the
