求正则匹配 第一行#e#之前的字符
高先生今年才25岁,但已经是一家企业的部门经理。#e#
高先生不放心,又用另外一个股票软件登录,结果显示仍然是1亿。这个时候他是既兴奋,又忐忑。
短短5个小时内,高先生经历了一场财富过山车。现在,高先生存下了这张1亿元的截图,认为这是件特有面子的事,毕竟自己的股票账户里曾经躺着笔巨款。不过,面对这种“大喜大悲”,高先生也想给自己讨个说法。
2007年,因从小独立照顾身患尿毒症的母亲并成功考取大学,背母上学的21岁浙江男孩刘霆被评为“全国道德模范”。2014年,28岁的刘霆宣告变性成为一个女孩并改名刘婷。从道德模范到变性人,从男人到女人,从质疑到祝福,一路走来刘婷在扎挣中度过。然而变性后的她,生活才刚刚开始,面对未来的挑战,她已做好了准备。#p#e#

求一正则 匹配 ,

规则:匹配 第一行#e#之前的字符(包括#e#)

结果匹配:高先生今年才25岁,但已经是一家企业的部门经理。#e#

我用 [\d\D\w\W\s\S]*[#e#] 匹配出了全部

用它的意图是删除第一行#e#之前的字符。
$body = preg_replace("/[\d\D\w\W\s\S]*[#e#]+/","",$body);
------解决思路----------------------

$s =<<< TXT<br />高先生今年才25岁,但已经是一家企业的部门经理。#e#<br />高先生不放心,又用另外一个股票软件登录,结果显示仍然是1亿。这个时候他是既兴奋,又忐忑。<br />短短5个小时内,高先生经历了一场财富过山车。现在,高先生存下了这张1亿元的截图,认为这是件特有面子的事,毕竟自己的股票账户里曾经躺着笔巨款。不过,面对这种“大喜大悲”,高先生也想给自己讨个说法。<br />2007年,因从小独立照顾身患尿毒症的母亲并成功考取大学,背母上学的21岁浙江男孩刘霆被评为“全国道德模范”。2014年,28岁的刘霆宣告变性成为一个女孩并改名刘婷。从道德模范到变性人,从男人到女人,从质疑到祝福,一路走来刘婷在扎挣中度过。然而变性后的她,生活才刚刚开始,面对未来的挑战,她已做好了准备。#p#e#<br />TXT;<br />echo preg_replace('/.+#e#/', '', $s);

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
