In Laravel 6, after the array is operated based on the array-related function, the same input, the analysis of the differences under different execution orders (include, reference)
1. The code implementation of the PHP file is as follows
<?php
use Illuminate\Support\Arr;
use Illuminate\Support\Facades\Log;
Log::info(
'v2.1.3_migrate_index.php_schema_0',
[
'schema' => $schema
]
);
$settings = ['text_color', 'mask_opacity', 'button_text_color', 'button_background_color'];
if (Arr::has($schema, 'sections')) {
foreach ($schema['sections'] as $sectionKey => $section) {
if (Arr::get($section, 'type') == 'multi-column') {
foreach ($settings as $setting) {
if (Arr::has($section, 'settings.' . $setting)) {
if ($setting == 'mask_opacity') {
$value = (bool)Arr::get($section, 'settings.' . $setting);
} else {
$value = Arr::get($section, 'settings.' . $setting);
}
foreach ($section['blocks'] as $blockKey => $block) {
Arr::set($schema, 'sections.' . $sectionKey . '.blocks.' . $blockKey . '.settings.' . $setting, $value);
}
Arr::forget($schema, 'sections.' . $sectionKey . '.settings.' . $setting);
}
}
}
}
}
Log::info(
'v2.1.3_migrate_index.php_schema_1',
[
'schema' => $schema
]
);
return $schema;
2. The initial $schema , that is[2023-05-17 09:45:23]local.info: v2.1.3_migrate_index.php_schema_0 , its values are as follows
{
"schema": {
"sections": {
"4imagetext_t0upqwh3": {
"type": "multi-column",
"disabled": false,
"settings": {
"heading": "",
"heading_align": "center",
"text_color": "#000",
"image_size": "auto",
"mask_opacity": 0,
"button_text_color": "#000",
"button_background_color": "#fff",

},
"blocks": {
"column-0": {
"type": "column",
"settings": {
"heading": "IMAGE WITH TEXT",
"text": "Use these blocks to share your brand's story. You can focus on a particular collection, a product detail, or even embed a video.",
"image": "https://cdn.cloudfastin.com/image/cafe2c8e6451a85f66aedbc62af22747f711c3f2.jpeg",
"mobile_image": "",

}
},
"column-1": {
"type": "column",
"settings": {
"heading": "IMAGE WITH TEXT",
"text": "Use these blocks to share your brand's story. You can focus on a particular collection, a product detail, or even embed a video.",
"image": "https://cdn.cloudfastin.com/image/b55803eeb93eba8bb0b8bc4bb4be7ad16df74ad1.jpeg",

},

"mobile_image": "",
"url": "/",
"label": "MORE INFO"
}
}
},
"block_order": [
"column-0",
"column-1",
"column-2"
]
}
},
"order": [
"4imagetext_t0upqwh3"
]
}
}
3, however, the returned $schema , i.e.[2023-05-17 09:45:23]local.info: v2.1.3_migrate_index.php_schema_1 , not as expected. Its data is lost. The fields in sections.4imagetext_t0upqwh3 have been lost. as shown in Figure 1
![但是，返回的 $schema ，即 [2023-05-17 09:45:23] local.INFO: v2.1.3_migrate_index.php_schema_1 ，不符合预期。其数据有丢失。在 sections.4imagetext_t0upqwh3 中的字段：type、settings、block_order 等皆已经丢失。](https://www.shuijingwanwq.com/wp-content/uploads/2023/06/1-6.png)

{
"schema": {
"sections": {
"4imagetext_t0upqwh3": {
"blocks": {
"column-0": {
"settings": {
"button_background_color": "#fff"
}
},
"column-1": {
"settings": {
"button_background_color": {
"blocks": {
"column-0": {
"settings": {
"button_background_color": "#fff"
}

}
},

}
},
"column-1": {
"settings": {
"button_background_color": {
"blocks": {
"column-0": {
"settings": {
"button_background_color": "Over 15 levels deep, aborting normalization"

}
}
}
}
}
}
}
}
}
}
},
"order": [
"4imagetext_t0upqwh3"
]
}
}
4. However, only executing this php file, the returned $schema is as expected. The execution of the third step is not as expected, and the root cause should be that somewhere before the execution of this PHP file affects the execution of this PHP file.
{
"schema": {
"schema": {
"order": [
"4imagetext_t0upqwh3"
],
"sections": {
"4imagetext_t0upqwh3": {
"type": "multi-column",
"blocks": {
"column-0": {
"type": "column",
"settings": {
"url": "/",
"text": "Use these blocks to share your brand's story. You can focus on a particular collection, a product detail, or even embed a video.",
"image": "https://cdn.cloudfastin.com/image/cafe2c8e6451a85f66aedbc62af22747f711c3f2.jpeg",
"label": "MORE INFO",
"heading": "IMAGE WITH TEXT",
"mobile_image": ""
}
},
"column-1": {
"type": "column",
"settings": {
"url": "/",
"text": "Use these blocks to share your brand's story. You can focus on a particular collection, a product detail, or even embed a video.",
"image": "https://cdn.cloudfastin.com/image/b55803eeb93eba8bb0b8bc4bb4be7ad16df74ad1.jpeg",
"label": "MORE INFO",
"heading": "IMAGE WITH TEXT",
"mobile_image": ""
}
},
"column-2": {
"type": "column",
"settings": {

"mobile_image": ""
}
}
},
"disabled": false,
"settings": {
"heading": "",
"image_size": "auto",
"text_align": "center",
"text_color": "#000",
"mask_opacity": 0,
"heading_align": "center",
"button_text_color": "#000",
"button_background_color": "#fff"
},
"block_order": [
"column-0",
"column-1",
"column-2"
]
}
}
}
}
}
5. The reason was finally confirmed, because before executing this php file, another php file was executed, and the reference was used in another php file: &$value. The sequential execution of the two PHP files is to use include .
<?php
use Illuminate\Support\Arr;
if (Arr::has($schema, 'sections'))
{
foreach ($schema['sections'] as &$value) {
// ...
}
}
return $schema;
6. Replace $Value with $SectionSettingValue, and temporarily avoid the problem of the variable name with the same name.
