1. Use the idea of ​​recursion

<span style="color: #0000ff">function</span> mkdirs_2(<span style="color: #800080">$path</span><span style="color: #000000">){
</span><span style="color: #0000ff">if</span>(!<span style="color: #008080">is_dir</span>(<span style="color: #800080">$path</span><span style="color: #000000">)){
mkdirs_2(</span><span style="color: #008080">dirname</span>(<span style="color: #800080">$path</span><span style="color: #000000">));
</span><span style="color: #0000ff">if</span>(!<span style="color: #008080">mkdir</span>(<span style="color: #800080">$path</span>, 0777<span style="color: #000000">)){
</span><span style="color: #0000ff">return</span> <span style="color: #0000ff">false</span><span style="color: #000000">;
}
}
</span><span style="color: #0000ff">return</span> <span style="color: #0000ff">true</span><span style="color: #000000">;
}
</span><span style="color: #008000">/*</span><span style="color: #008000"> http://www.manongjc.com/article/1331.html </span><span style="color: #008000">*/</span>
<span style="color: #800080">$path2</span> = 'sdfs/sds/sds/s/s/sss'<span style="color: #000000">;
</span><span style="color: #008080">var_dump</span>(mkdirs_2(<span style="color: #800080">$path2</span>)); <span style="color: #008000">//</span><span style="color: #008000">true;</span>

1. The main idea is to use recursion, first create dir, then create dir/css, then create...

2. Recursion is the process of pushing onto the stack, So let dir/css/js/php/ok be pushed onto the stack first, then it will pop out last... I won’t say anything else.
3.dirname(path) returns is the value of the path except the last directory, that is, the first return is: dir/css/js/php,, the second return is dir/css/js,, and the last return is ./


2. Create directly using mkdir(), the third parameter must be true to automatically create multi-level directories

<span style="color: #0000ff">function</span> mkdirs_1(<span style="color: #800080">$path</span>, <span style="color: #800080">$mode</span> = 0777<span style="color: #000000">){
</span><span style="color: #0000ff">if</span>(<span style="color: #008080">is_dir</span>(<span style="color: #800080">$path</span><span style="color: #000000">)){
</span><span style="color: #0000ff">return</span> '无法创建,已经是目录了'<span style="color: #000000">;
}</span><span style="color: #0000ff">else</span><span style="color: #000000">{
</span><span style="color: #0000ff">if</span>(<span style="color: #008080">mkdir</span>(<span style="color: #800080">$path</span>, <span style="color: #800080">$mode</span>, <span style="color: #0000ff">true</span><span style="color: #000000">)) {
</span><span style="color: #0000ff">return</span> '创建成功'<span style="color: #000000">;
}</span><span style="color: #0000ff">else</span><span style="color: #000000">{
</span><span style="color: #0000ff">return</span> '创建失败'<span style="color: #000000">;
}
}
}
</span><span style="color: #008000">/*</span><span style="color: #008000"> http://www.manongjc.com/article/1332.html </span><span style="color: #008000">*/</span>
<span style="color: #800080">$path1</span> = 'a/b/c/d/e'<span style="color: #000000">;
</span><span style="color: #008080">var_dump</span>(mkdirs_1(<span style="color: #800080">$path1</span>)); <span style="color: #008000">//</span><span style="color: #008000">string '创建成功' (length=12)</span>

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
