This article mainly explains "how to replace the value of an array with an asterisk by php". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how php replaces the value of an array to an asterisk.

You can replace the array value with an asterisk with array_splice (). If you want to replace only one value, you can use "array_splice (array, start position, 1, *"); if you want to replace multiple values, you can use "array_splice (array, position, replace number, replace array)", which contains multiple replacement values.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

In php, you can use the array_splice () function to replace the value of an array with an asterisk.

Array_splice () is a powerful function that removes, inserts, and replaces elements.

Using the array_splice () function, you can replace a specified number of elements from a specified position. If you replace multiple values, the replacement value can be an array.

Array_splice ($array,$start,$length,$replacement)

Parameters:

Arr represents an array.

Start indicates where to start the deletion (subscript):

If start is positive, it is deleted from after going.

If the start is negative, it is deleted from back to front, starting from the end of the arr-start. For example,-2 means starting with the penultimate element of the array.

Length is an optional parameter that indicates the number of elements deleted:

If length is positive, it means deleting length elements

If length is negative, all elements from start to the reciprocal length at the end of the array will be deleted

If omitted, all elements from start to the end of the array are deleted.

Replacement is an optional parameter that represents the value to replace. If replacement has more than one value, it needs to be set to an array, and if there is only one value, it can not be set to an array.

If you are performing a replacement operation, the duration value and the number of replacement need to be the same.

Example 1: one value of the replacement array is an asterisk

Example 2: multiple values of the replacement array are asterisks

If multiple values are replaced, the replacement value is an array; and the number of substitutions should be the same as the length of the replacement array.

At this point, I believe you have a deeper understanding of "how to replace the value of an array with an asterisk by php". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
