wp_image_src_get_dimensions: 这个函数用来获取一个图像文件的宽度和高度尺寸。它接受一个参数,即图像文件的路径,并返回一个包含宽度和高度键及其各自数值的数组。

根据源文件确定图片的宽度和高度尺寸。

function wp_image_src_get_dimensions( $image_src, $image_meta, $attachment_id = 0 ) {
	$dimensions = false;

	// Is it a full size image?
	if (
		isset( $image_meta['file'] ) &&
		strpos( $image_src, wp_basename( $image_meta['file'] ) ) !== false
	) {
		$dimensions = array(
			(int) $image_meta['width'],
			(int) $image_meta['height'],
		);
	}

	if ( ! $dimensions && ! empty( $image_meta['sizes'] ) ) {
		$src_filename = wp_basename( $image_src );

		foreach ( $image_meta['sizes'] as $image_size_data ) {
			if ( $src_filename === $image_size_data['file'] ) {
				$dimensions = array(
					(int) $image_size_data['width'],
					(int) $image_size_data['height'],
				);

				break;
			}
		}
	}
