How can I use grep to show just filenames on Linux?

How can I use grepto show just file-names (no in-line matches) on Linux?
如何grep在 Linux 上仅显示文件名（无内联匹配）？
I am usually using something like:
我通常使用类似的东西：
find . -iname "*php" -exec grep -H myString {} \;
How can I just get the file-names (with paths), but without the matches? Do I have to use xargs? I didn't see a way to do this on my grepman page.
我怎样才能获得文件名（带路径），但没有匹配项？我必须使用xargs吗？我在grep手册页上没有看到执行此操作的方法。

The standard option grep -l(that is a lowercase L) could do this.
标准选项grep -l（即小写 L）可以做到这一点。
From the Unix standard:
从Unix 标准：
-l
(The letter ell.) Write only the names of files containing selected
lines to standard output. Pathnames are written once per file searched.
If the standard input is searched, a pathname of (standard input) will
be written, in the POSIX locale. In other locales, standard input may be
replaced by something more appropriate in those locales.
You also do not need -Hin this case.
-H在这种情况下你也不需要。

From the grep(1)man page:
从grep(1)手册页：
-l, --files-with-matches Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match. (-l is specified by POSIX.)

For a simple file search you could use grep's -land -roptions:
对于简单的文件搜索，您可以使用 grep-l和-r选项：
grep -rl "mystring"
All the search is done by grep. Of course, if you need to select files on some other parameter, find is the correct solution:
所有的搜索都是由grep完成的。当然，如果您需要在其他参数上选择文件， find 是正确的解决方案：
find . -iname "*.php" -execdir grep -l "mystring" {} +
The execdiroption builds each grep command per each directory, and concatenates filenames into only one command (+).
该execdir选项为每个目录构建每个 grep 命令，并将文件名连接成一个命令 ( +)。

My Command suggestion
我的命令建议
sudo find /home -name *.php
The output from this command on my Linux OS:
此命令在我的 Linux 操作系统上的输出：
compose-sample-3/html/mail/contact_me.php
compose-sample-3/html/mail/contact_me.php
As you require the filename with path, enjoy!
当您需要带路径的文件名时，请尽情享受！
