How to remove the first character of a string in php?

You can use the substr() function in PHP to remove the first character of a string. The syntax is "substr(string,start,length)", just set the start parameter to "1". For example, "substr("Hello world",1)" removes the leading character "h".

Example: php removes the first character of the string

<?php
echo substr("Hello world",1);
?>

Running result:

ello world

Description:

The substr() function returns a part of the string.

Note: If the start parameter is negative and length is less than or equal to start, length is 0.

Syntax

substr(string,start,length)

Parameters

string Required. Specifies a part of the string to be returned.

start Required. Specifies where in the string to begin.

• Positive number - starts at the specified position in the string

• Negative number - starts at the specified position from the end of the string

• 0 - Start at the first character in the string

length optional. Specifies the length of the string to be returned. The default is until the end of the string.

• Positive number - Return from the position of the start parameter

• Negative number - Return from the end of the string

Return value: Returns the extracted part of the string, returns FALSE if it fails, or returns an empty string.

In PHP 5.2.2 to 5.2.6 versions, if the start parameter indicates a negative truncation or an out-of-bounds position, FALSE is returned. Other versions get the string starting at the start position.
