__( ‘Hello world’, ‘text-domain’ ); _e( ‘Hello world’, ‘text-domain’ );.

/**

esc_html__( ‘Hello world’, ‘text-domain’ ); esc_html_e( ‘Hello world’, ‘text-domain’ );

/**

wp_kses( __( ‘Hello world’, ‘text-domain’ ), $allowed_html_array );

@joyously - Here's an option if you're not wanting any tags from the title to appear:

<?php

edit_post_link(
	sprintf(
		// Translators: %s is the post title shown to screen readers.
		esc_html__( 'Edit%s' ),
		' <span class="screen-reader-text">' . wp_strip_all_tags( get_the_title() ) . '</span>'
	)
);

Thanks, I think @justintadlock has the best version since the HTML is of no use to screen readers.
But I've been thinking lately that the screen reader user might be better off with "Edit current post", rather than "Edit Hello World!".

i am currently working with codeigniter can i use html_escape?
