PHP preg_replace - text will not be recognized


PHP preg_replace - text will not be recognized

like below fixes the issue $ is a special character for regex (it means end of line), you have to escape it: \$ and because you are using a variable that contains the regex and pass it as a parameter of the function, you have to triple escape:
code :
$insert_marker = "/##-- \\\$Id: _.htaccess 10934 2017-08-31 12:11:28Z serpent_driver \\\$/";

may help you . It's indeed the UTF-8 encoding 11000010 10100000 of NBSP \xA0. As said earlier, this works:
code :
= preg_replace('/<p>\p{Z}*<\/p>/u', '<p class="notmobile"> </p>', $f);

I wish this help you By default the PHP regex engine considers your string as a suit of bytes (i.e. as a suit of one byte characters).
When you use the u modifier, the regex engine changes two things:
code :
(*UTF8)(*UCP)yourpattern

I wish this helpful for you You should not use photo capture like this. According to documentation - extras.get("data") contains small preview and should not be used for other purposes then showing preview. You should use camera the other way. There is a Kotlin sample from my library. It creates file in DCIM dir and pass to Camera it's URI to use as output:
code :
private fun takePhoto() {
    val photoIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
    val dirDCIM = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
    val storageDir = File(dirDCIM, "/${config.cameraFolderName}/")
    if (!storageDir.exists()) storageDir.mkdirs()

    currentCameraImageFile = File(storageDir, "photo_${UUID.randomUUID()}.jpg")
    val uri =
        FileProvider.getUriForFile(this, "$packageName.fileprovider", currentCameraImageFile!!)
    photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri)

    val resolvedIntentActivities =
        packageManager.queryIntentActivities(photoIntent, PackageManager.MATCH_DEFAULT_ONLY)
    for (resolvedIntentInfo in resolvedIntentActivities) {
        val packageName = resolvedIntentInfo.activityInfo.packageName
        grantUriPermission(
            packageName,
            uri,
            Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION
        )
    }

    startActivityForResult(photoIntent, PHOTO_REQUEST_CODE)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    when (requestCode) {
        PHOTO_REQUEST_CODE -> {
            val photoFile = currentCameraImageFile ?: return
            if (resultCode == Activity.RESULT_OK && photoFile.exists()) {
                // Do your stuff
            } else {
                // If result is not successful - delete temporary photo file
                photoFile.delete()
            }
            currentCameraImageFile = null
        }
    }
}
