PHP dan Python masing -masing mempunyai kelebihan sendiri, dan pilihannya harus berdasarkan keperluan projek. 1.Php sesuai untuk pembangunan web, dengan sintaks mudah dan kecekapan pelaksanaan yang tinggi. 2. Python sesuai untuk sains data dan pembelajaran mesin, dengan sintaks ringkas dan perpustakaan yang kaya.

PHP tidak mati, tetapi sentiasa menyesuaikan diri dan berkembang. 1) PHP telah menjalani beberapa lelaran versi sejak tahun 1994 untuk menyesuaikan diri dengan trend teknologi baru. 2) Ia kini digunakan secara meluas dalam e-dagang, sistem pengurusan kandungan dan bidang lain. 3) Php8 memperkenalkan pengkompil JIT dan fungsi lain untuk meningkatkan prestasi dan pemodenan. 4) Gunakan OPCACHE dan ikut piawaian PSR-12 untuk mengoptimumkan prestasi dan kualiti kod.

Masa depan PHP akan dicapai dengan menyesuaikan diri dengan trend teknologi baru dan memperkenalkan ciri -ciri inovatif: 1) menyesuaikan diri dengan pengkomputeran awan, kontena dan seni bina microservice, menyokong Docker dan Kubernetes; 2) memperkenalkan pengkompil JIT dan jenis penghitungan untuk meningkatkan prestasi dan kecekapan pemprosesan data; 3) Berterusan mengoptimumkan prestasi dan mempromosikan amalan terbaik.

Dalam PHP, sifat sesuai untuk situasi di mana penggunaan semula kaedah diperlukan tetapi tidak sesuai untuk warisan. 1) Ciri membolehkan kaedah multiplexing dalam kelas untuk mengelakkan pelbagai kerumitan warisan. 2) Apabila menggunakan sifat, anda perlu memberi perhatian kepada konflik kaedah, yang dapat diselesaikan melalui alternatif dan sebagai kata kunci. 3) Tua yang berlebihan harus dielakkan dan tanggungjawab tunggalnya harus dikekalkan untuk mengoptimumkan prestasi dan meningkatkan pemeliharaan kod.

Kontena Suntikan Ketergantungan (DIC) adalah alat yang menguruskan dan menyediakan kebergantungan objek untuk digunakan dalam projek PHP. Manfaat utama DIC termasuk: 1. Decoupling, membuat komponen bebas, dan kod itu mudah dikekalkan dan diuji; 2. Fleksibiliti, mudah untuk menggantikan atau mengubah suai kebergantungan; 3. Keseluruhan, mudah untuk menyuntik objek mengejek untuk ujian unit.

SplfixedArray adalah pelbagai saiz tetap dalam PHP, sesuai untuk senario di mana prestasi tinggi dan penggunaan memori yang rendah diperlukan. 1) Ia perlu menentukan saiz apabila membuat untuk mengelakkan overhead yang disebabkan oleh pelarasan dinamik. 2) Berdasarkan pelbagai bahasa C, secara langsung mengendalikan memori dan kelajuan akses cepat. 3) Sesuai untuk pemprosesan data berskala besar dan persekitaran sensitif memori, tetapi ia perlu digunakan dengan berhati-hati kerana saiznya tetap.

PHP mengendalikan fail muat naik melalui pembolehubah fail $ \ _. Kaedah untuk memastikan keselamatan termasuk: 1. Semak kesilapan muat naik, 2. Sahkan jenis dan saiz fail, 3. Mencegah penindasan fail, 4. Pindahkan fail ke lokasi storan tetap.

Dalam JavaScript, anda boleh menggunakan NullcoalescingOperator (??) dan NullcoalescingAssignmentOperator (?? =). 1.? Menerapkan semula operan pertama yang tidak berselisih atau tidak ditentukan. 2.?? Pengendali ini memudahkan logik kod, meningkatkan kebolehbacaan dan prestasi.
