php array数组生成csv文件
在php中生成csv文件的方法很是简单,这里我来介绍一下自己用到的一个实例,把数组直接转换成csv文件输出,有需要了解的朋友可参考,代码如下:
<?php $data = array( array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ), array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ), array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ), ); $filename = "example"; header("Content-type: text/csv"); header("Content-Disposition: attachment; filename={$filename}.csv"); header("Pragma: no-cache"); header("Expires: 0"); outputCSV($data);
function outputCSV($data) { $outputBuffer = fopen("php://output", 'w'); foreach($data as $val) { foreach ($val as $key => $val2) { $val[$key] = iconv('utf-8', 'gbk', $val2);// CSV的Excel支持GBK编码,一定要转换,否则乱码 } fputcsv($outputBuffer, $val); } fclose($outputBuffer); }
例2,看一个读取csv文件的实例,读取cvs,使用fgetcsv()文件指针中读入一行并解析 CSV 字段,比如说我要读取如下csv文件,代码如下:
<?php /** by www.phprm.com */ $row = 1; $handle = fopen("file.csv","r"); //fgetcsv() 解析读入的行并找出 CSV格式的字段然后返回一个包含这些字段的数组。 while ($data = fgetcsv($handle, 1000, ",")) { $num = count($data); echo "<p> $num fields in line $row: <br>\n"; $row++; for ($c=0; $c < $num; $c++) { //注意中文乱码问题 $data[$c]=iconv("gbk", "utf-8//IGNORE",$data[$c]); echo $data[$c] . "<br>\n"; } } fclose($handle);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
