exif_read_data Function synopsis

exif_read_data(
    $file,
    ?string $required_sections = null,
    bool $as_arrays = false,
    bool $read_thumbnail = false
  ): array|false

Parameters

$file

The location of the image file. This can either be a path to the file (stream wrappers are also supported as usual) or a stream resource.

$required_sections

OptionalType?stringDefault valuenull

Is a comma separated list of sections that need to be present in file to produce a result array. If none of the requested sections could be found the return value is false.

$required_sections accepts one of the following string values:

• FILE
• COMPUTED
• ANY_TAG
• IFD0
• THUMBNAIL
• COMMENT
• EXIF

$as_arrays

OptionalTypeboolDefault valuefalse

Specifies whether or not each section becomes an array. The $required_sections COMPUTED, THUMBNAIL, and COMMENT always become arrays as they may contain values whose names conflict with other sections.

$read_thumbnail

OptionalTypeboolDefault valuefalse

When set to true the thumbnail itself is read. Otherwise, only the tagged data is read.

Return value

Typearray|false

It returns an associative array where the array indexes are the header names and the array values are the values associated with those headers. If no data can be returned, exif_read_data will return false.
