You can set environment variables by modifying this file.</p><p>We divide the environment variables supported by static-php-cli into three types:</p><ul><li>Global internal environment variables: declared after static-php-cli starts, you can use <code>getenv()</code> to get them internally in static-php-cli, and you can override them before starting static-php-cli.</li><li>Fixed environment variables: declared after static-php-cli starts, you can only use <code>getenv()</code> to get them, but you cannot override them through shell scripts.</li><li>Config file environment variables: declared before static-php-cli build, you can set these environment variables by modifying the <code>config/env.ini</code> file or through shell scripts.</li></ul><p>You can read the comments for each parameter in <a href="https://github.com/crazywhalecc/static-php-cli/blob/main/config/env.ini" target="_blank" rel="noreferrer">config/env.ini</a> to understand its purpose.</p><h2 id="custom-environment-variables" tabindex="-1">Custom environment variables <a class="header-anchor" href="#custom-environment-variables" aria-label="Permalink to "Custom environment variables""></a></h2><p>Generally, you don't need to modify any of the following environment variables as they are already set to optimal values. However, if you have special needs, you can set these environment variables to meet your needs (for example, you need to debug PHP performance under different compilation parameters).</p><p>If you want to use custom environment variables, you can use the <code>export</code> command in the terminal or set the environment variables directly before the command, for example:</p><div class="language-shell vp-adaptive-theme"><button title="Copy Code" class="copy"></button><span class="lang">shell</span><pre class="shiki shiki-themes github-light github-dark vp-code" tabindex="0"><code><span class="line"><span style="--shiki-light:#6A737D;--shiki-dark:#6A737D;"># export first</span></span>
