php与xul
PHP & XUL
很早就知道XUL是什么东西,但一直未用过,直到今天在David Sklar的BLOG上看到这篇关于XUL的文章(Creating Rich Applications with Mozilla, XUL, and AMP Technology)。
一、什么是XUL?
XUL即XML-based User Interface Language的缩写,是一种基于XML的界面设计语言,提供了各种各样的元件(elements)和物件(widgets)。它可以在 Mozilla 家族的所有产品中运行。
其实就跟微软大势宣扬的XAML一样,未来没有C/S或者B/S可言。至于XUL和XAML这两者谁效仿谁,就不是我们这些最终用户该研究的了:)
二、牛刀小试
<?php
function genFunctionPanel() {
$exts = get_loaded_extensions();
natsort($exts);
$xul = '<tree flex="1">
<treecols>
<treecol label="函数列表" flex="1" primary="true"/>
</treecols>
<treechildren>';
foreach ($exts as $ext) {
$funcs = get_extension_funcs($ext);
if (count($funcs)) {
$xul .= '<treeitem container="true">
<treerow>
<treecell label="'. $ext .'" />
</treerow>
<treechildren>';
foreach ($funcs as $function) {
$xul .= '<treeitem>
<treerow>
<treecell label="'. $function .'" />
</treerow>
</treeitem>';
}
$xul .= '</treechildren></treeitem>';
}
}
$xul .= '</treechildren></tree>';
return $xul;
}
function genConstantPanel() {
$xul = '<listbox flex="1">
<listcols>
<listcol flex="1"/>
<splitter />
<listcol flex="1"/>
</listcols>
<listhead>
<listheader label="常量" />
<listheader label="值" />
</listhead>';
foreach (get_defined_constants() as $const => $value) {
$xul .= '<listitem>
<listcell label="'. $const .'" />
<listcell label="'. $value .'" />
</listitem>';
}
$xul .= '</listbox>';
return $xul;
}
$functions = genFunctionPanel();
$constants = genConstantPanel();
$xul = <<< EOD
