PHP curl下载图片的方法

PHP curl下载图片的方法


<?php


$images = [
  'http://wx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTKPkia3rxjuBoSQ1sUSmqYXDazibuIp8p2CCialBPjeYvcNJgky9P7hmlnDKgzX91utEQPu7VtsDqAIg/0',

function download($url, $path = 'dowloadceshi/2015-09-22_00-17-06j.png')
{
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
  $file = curl_exec($ch);

  curl_close($ch);
  $filename = pathinfo($url, PATHINFO_BASENAME);

  $resource = fopen($path, 'a');
  fwrite($resource, $file);
  fclose($resource);
}

foreach ( $images as $url ) {
  download($url);
}
?>

ps:如果采用file_get_contents方法发生图片下载过慢

php sublime常用插件

php sublime常用插件

1 Sublime Text的默认设置是不开启显示编码的,如果想开启,可通过菜单Perference → Settings – User,在打开的配置文件里 ,在大括号后面,增加以下内容:// Display file encoding in the status bar”show_encoding”: true,// Display line endings in the status bar”show_line_endings”: true,此时保存该配置文件,就能够看到sublime最底下一行会显示文件编码格式了。以上的配置内容在Perference → Setting─Default都是false的。 注意需要复制到user才能改 默认改不了

2 常用的快捷键
ctrl+p可以快速查找文件

3安装风格spacegray
直接用pci安装 搜索spacegray
安装玩然后选择就行了 另外修改下配置文件

   "theme": "Spacegray.sublime-theme",
"color_scheme": "Packages/Theme - Spacegray/base16-ocean.dark.tmTheme",
    "highlight_line": true,
 
    "spacegray_sidebar_font_xlarge": true,
    "spacegray_sidebar_tree_large": true,
    "spacegray_tabs_auto_width": true,
    "spacegray_tabs_font_large": true,
    "spacegray_tabs_xlarge": true,
 
    "line_padding_bottom": 3,
    "line_padding_top": 3,
 
	"font_size": 14

4 SideBarEnhancements插件安装 用于新建 复制文件

5ctrl+R查找函数 还有个brow 什么package里面 新建个Default (Windows).sublime-mousemap 然后

[
{
"button": "button2",
"count": 1,
"modifiers": ["ctrl"],
"command": "jump_back"
},


{
"button": "button1",
"count": 1,
"modifiers": ["ctrl"],
"press_command": "drag_select",
"command": "goto_definition"
}
]

复制进去 就支持ctrl+左键了 ctrl+右键还可以跳回

5 设置键盘快捷键 格式化代码

{ "keys": ["ctrl+alt+l"], "command": "reindent" }

6 Clipboard History插件
Ctrl+shift+v:可以看到粘贴历史

7 Bracket Highlighter
功能:代码匹配

简介:可匹配[], (), {}, “”, ”, ,高亮标记,便于查看起始和结束标记

使用:点击对应代码即可

8 开启PHP报错提示
sublimeliner

sublimeliner-php 两个

安装好了之后

打开preferences -> package-setting -> sublimeliner-> settings–user

“mark_style”: “outline”,
“no_column_highlights_line”: false,
“passive_warnings”: true,
“paths”: {
“linux”: [],
“osx”: [],
“windows”: [
“D:\\wamp\\bin\\php\\php5.5.12”
]
},
“python_paths”: {
“linux”: [],
“osx”: [],
“windows”: []
},

就是添加一下 paths的参数值,指定一下你本地php目录。

然后关闭sublime,再次打开一个php脚本,试试吧。

有错误的地方在行号上会有红点提示在代码上会有红色方框,鼠标放红色方框上,错误信息在编辑器底部状态栏显示。

9格式化用codeformatter插件 php设置下路径就好
html配置需要调整下 不然格式后会报错
“formatter_version”: “regexp”, //

php [poolwww] seemsbusy (youmayneedto increasepm.start_servers, or pm.min/max_spare_servers)错误解决方法

php [poolwww] seemsbusy (youmayneedto increasepm.start_servers, or pm.min/max_spare_servers)错误解决方法
修改php-fpm.conf配置文件

pm.max_children = 1024

; The number of child processes created on startup.
; Note: Used only when pm is set to ‘dynamic’
; Default Value: min_spare_servers + (max_spare_servers – min_spare_servers) / 2
pm.start_servers = 512

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to ‘dynamic’
; Note: Mandatory when pm is set to ‘dynamic’
pm.min_spare_servers = 4

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to ‘dynamic’
; Note: Mandatory when pm is set to ‘dynamic’
pm.max_spare_servers = 512

PHP failed to ptrace(PEEKDATA) pid 13659: Input/output error错误解决方法

PHP failed to ptrace(PEEKDATA) pid 13659: Input/output error错误解决方法

现在改linux内核文件打开限制

ulimit -SHn 51200

再修改nginx.conf配置文件

worker_rlimit_nofile 51200;

最后修改PHP-fpm.conf配置文件

rlimit_files = 51200

这3个一定要设置一样哦

2个必须保持一致就可以了
