たとえば、次のようなコードがあります。

すべての Wordpress フックを一致させたい: 「do_action」と「apply_filters」と 3 つのオプション: apply_filters( 'woocommerce_order_tax_totals', $tax_totals, $this ), file, line number
私がやろうとしていることの例をここで見ることができます: http://etivite.com/api-hooks/buddypress/trigger/apply_filters/bp_get_total_mention_count_for_user/
http://adambrown.info/p/wp_hooks/hook/activated_plugin?version=3.6&file=wp-admin/includes/plugin.php
私は何かを引き出そうとしましたが、成功しませんでした:
<?php
$path = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/plugins/iphorm-form-builder';
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename) {
if (substr($filename, -3) == 'php') {
$file = file($filename);
if ($file !== false) {
$matches1 = preg_grep( '/do_action\((.+)\);/', $file);
$matches2 = preg_grep( '/apply_filters\((.+)\);/', $file );
$arr = array_filter(array_merge($matches1, $matches2));
$out = '';
echo "found in $filename:";
echo "<pre>";
foreach ($arr as $key => $value) {
$out .= $file[$key-2];
$out .= $file[$key-1];
$out .= $file[$key];
$out .= $file[$key+1];
$out .= $file[$key+2];
}
echo htmlentities($out);
echo "</pre>";
} else {
echo "failed reading to array";
}
}
}
