实现string '越野,城市SUB' (length=16)
与数组里的'wjc_title' => string '2厢小轿车' (length=13)比对,看是否有满足条件的,
怎么搞,刚学习PHP不久
回复讨论(解决方案)
不要贴图,贴出你的数组。
说明一下满足条件是指什么?

string '越野,城市SUB' 与数组$list中的wjc_title比较,看数组中是否存在?数组打印出来如上图
遍历你第一个数组中的每个值在第二个中是否存在?
贴出你的文本数组, 否则人家还要花时间构造你的数组。

第一个是ajax传过来的多选值,第二个$list是查询数据得到的。
我不是要问你两个数组是怎么得到的,是想问你想输出什么,想得到什么结果。

好吧版主辛苦。。。比对,如果有一个或两个匹配。true反子false
让你贴出你的数组就那么难呢,说得我口水都干了。
$ar1 = array('a1', 'a2');$ar2 = array( array('wjc_id' =>'12', 'wjc_title' =>'a1'), array('wjc_id' =>'23', 'wjc_title' =>'sfdsds'),);function foo($value){ global $ar2; $num = 0; foreach($ar2 as $v){ if($value == $v['wjc_title']) $num++; } return $num > 0;}foreach($ar1 as $v){ echo $v ."------"; var_dump(foo($v)). PHP_EOL;}a1------bool(true)
a2------bool(false)
foreach($list as $keys=>$values){ if(in_array($values['wjc_title'], $b)) { echo '继续'; }else { echo '结束'; }}
这样写好像有问题,是不是$b(第一个)要转换一下才能跟$list(第二个数组)比较,另外这样写每次循环都会输入结果,我想要比对完成后输出比对结果就行了

既如此,直接到数据库里查就是了

'在' : '不在', PHP_EOL;}a1 在
a2 不在

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
