    ▪使用dump函数,给php加断点测试       代码如下:function dump($var, $echo=true,$label=null, $strict=true){    $label = ($label===null) ? '' : rtrim($label) . ' ';    if(!$strict) {        if (ini_get('html_errors')) {            $output = print_r($var, true);.........

    ▪解析php多线程下载远程多个文件       代码如下:function remote($urls, $name = '', $path = '', $dir = './images/') { if (!is_array($urls) or count($urls) == 0) {  return false; } dmkdir($dir); $curl = $text = array(); foreach($urls as $k => $v) {  if (!empty($v) &&.........

    ▪基于php导出到Excel或CSV的详解(附utf8、gbk 编码转换)       php导入到excel乱码是因为utf8编码在xp系统不支持所有utf8编码转码一下就完美解决了utf-8编码案例Php代码 代码如下:<?php header("Content-Type: application/vnd.ms-excel; charset=UTF-8"); header("Pragma: public"); h.........
